FAQ's

The fan on the back of Impulse 6000D/7000DP is controlled by a thermostat IC. The thermostat utilizes an on/off control (i.e., not linear or continuous control). The thermostat IC is located next to the defibrillator load resistor.

There are two temperature thresholds. The lower threshold is set at about 40° C (104° F) and the upper threshold is set at about 50° C (122° F). When the temperature exceeds the low threshold, the fan turns on. When the temperature exceeds the upper threshold, a warning message is displayed and the unit will not make any further measurements until the temperature has dropped below the upper threshold.

A blinking red charge-status LED indicates a pending charge and should normally last a few seconds before turning solid red. If the blinking continues, the battery-charging circuit has determined that conditions are not correct to initiate the battery-charging cycle. The battery will not be charged if the battery temperature is too cold or too hot. The battery should be charged in an ambient temperature of 10° C to 40° C (50° F to 104° F)

Also, the battery will not be charged if the battery voltage is too low, which can happen if the Impulse 6000/7000DP has been stored for an extended period of time with a fully-discharged battery. In the "Charge Pending" mode, the battery-charging circuit charges the battery at a low rate, which will eventually bring the battery voltage high enough for the normal charge cycle to begin.

The answer to this question is somewhat counterintuitive. Battery pack gas-gauge ICs, such as the one used in the Impulse 6000D/7000DP, use a complex algorithm to estimate battery-charge state, taking into account time, temperature, and current flow. The self-discharge estimation (i.e., how much charge the battery loses over time during periods of non-use, sometimes called "shelf-life") is particularly sensitive to battery chemistry, and the shelf-life of today's NiMH cells is significantly longer than the algorithm built into the gas-gauge ICs can accommodate.

When an Impulse 6000D/7000DP is left idle for a few weeks and then powered-on, the battery charge level might be reported as 55 % when the true charge level might be 80 %. If the battery is then completely charged, which requires a 20 % increase in battery charge level, the charge level is only reported as 75 % (55 % plus 20 %).

To correct the reported charge level, use the "Train Battery" feature. To access this feature, press the [SETUP] key, then the [F1] softkey (labeled "Battery"), then press the [F3] softkey (labeled "Train Battery"), then follow the instructions presented on the screen. This procedure can take overnight to complete.

To keep the reported battery charge level as accurate as possible during extended periods of non-use, the Impulse 6000D/7000DP should be left connected to mains power via the battery charger with the unit powered off in an ambient temperature of 15° C to 26° C (60° F to 78° F). This will continuously trickle-charge the battery (the charge-status LED on the rear panel will be green) to keep both the actual and estimated battery charge level at 100 %.

Yes. Actually, to keep the reported battery charge level as accurate as possible during extended periods of non-use, it is recommend that the Impulse 6000D/7000DP be left connected to mains power via the battery charger with the unit powered off, in an ambient temperature of 15° C to 26° C (60° F to 78° F). This will continuously trickle-charge the battery (the charge-status LED on the rear panel will be green) to keep both the actual and estimated battery charge level at 100 %.

If the Impulse 6000D/7000DP cannot be kept connected to the battery charger during periods of non-use, the battery should be charged at least once a month. A unit with a discharged battery that is stored for an extended period of time will result in the battery becoming over-discharged, which is likely to result in permanent damage to the battery.

• Age of battery pack. The battery pack will lose some charge capacity over time.
• Use of the backlight display function. This option discharges the battery pack faster.
• 3. Operating the unit at the upper end of the specified operating temperature range, causing the internal fan to power on more often. This may especially be observed with multiple, rapid, high-energy defibrillator pulse discharges into the unit.

When using a laptop + docking station, after completing a test in an Ansur QED 6 test template, a [Q] command is sent from Ansur and is received by QED 6, but QED 6 doesn't go to its main screen (Main Menu 1), interrupting the serial communications and therefore the QED 6 and Ansur test template hangs. It recovers only if the QED 6 is restarted.

As a work around, we have implemented the following in Ansur QED 6 Plug-in ver. 1.0.3 (available for download from the Fluke Biomedical website):

If and when the serial communication hangs, Ansur prompts the user to click the QED 6 "more" soft key twice, as shown in the message box below (no need to restart QED 6).

The message box also appears if QED 6 is switched off or connected to different COM port (when run through normal desktop PC, or a laptop NOT connected via a docking station).

After clicking OK, the "Instrument not found" message appears and the user needs to select or re-select the COM port to which QED 6 is connected.

When running from laptop + docking station, the message boxes (Fig: 1 and Fig: 2) will repeat for each QED 6 test. For example: if a template has 5 QED 6 test elements, then the message box (Fig: 1) appears 5 times .

Alternative solutions include:

• Trade in the QED 6 for an Impulse 6000D or Impulse 70000DP and the Ansur Impulse6000D/7000DP Plug-in. See your local Fluke Biomedical representative for details and a quotation.
• Use QED 6 with Ansur by connecting QED 6 to an Edgeport Serial-to-USB Adapter/Converter and the Edgeport Serial-to-USB Adapter/Converter to one of the computer's USB ports. Google keyword Edgeport to find a distributor near you or purchase online from DigiKey.

1. Connect a personal computer running terminal emulation software (Example: MS Windows Hyperterminal) set to 2400 N 8 1 to com1 of the 505PRO
2. Turn the 505 PRO on.
3. Send the command "%U" (without quote marks).
   1. The 505 PRO should beep and the computer LED on the 505 PRO should illuminate and ok should be returned by the 505 PRO to the computer.
4. Send the command "#ID" and press enter.
   1. Unit will return: Model, X.XX, options
      1. Example 505 PRO, 2.09, RS (note if RS is not returned, the RS232 option is not installed. Please contact the factory to purchase this option.)

1. Upon power-up, the 505 Pro will display the software revision in an X.XX format, then automatically begin self-diagnostics; a one-second lamp test of all LEDs is performed as well as a one-second tone generation. The internal program memory and data memory also are tested for integrity.
2. During power up, the 505 Pro measures the line polarity and the voltage of the outlet it is plugged into and will indicate an error if the polarity is incorrect. If the polarity of the wall receptacle is reversed or the ground is open, the four-digit display will indicate POL or GND. If both conditions occur, the display will indicate GND.
3. If the wall receptacle polarity is reversed, the REV POL LED will flash when a reverse polarity test is performed on the device under test. If the wall receptacle ground is open, then the GND LED will flash during an open ground test on the device. The unit will not power-up if neutral line is open.
4. After initialization is complete, the 505 Pro will default to the single lead ground wire resistance test. In this test the circuit ground will be internally connected to the ground pin of the front panel outlet. The power to the front panel receptacle will be off and if the red lead is left not connected to anything the display will flash OR.

• Put your RF303RS into "simplex" mode. To do this:
  • With the RF303RSturned off, hold down the "+" and "-" softkeys (used to select load resistance)
  • With the "+" and "-" soft keys depressed, turn on the RF303RS. Wait a moment, then release the soft keys
• Your RF303RS is now in simplex mode. Using a straight-through serial cable, connect your printer to the RF303RS serial port. The RF303RS serial port is configured as follows: Baud rate is fixed at 2400. No parity, 1 stop bit. Configure your printer to the same settings the RF303RS uses, as shown above.
  • Turn on your printer. Put it "on line".
  • Take a power measurement reading. While the reading is being taken, push the "mode" button.
  • Data will be sent to your printer showing power in watts and current, as well as load resistance. Carriage Return and Line-feed signals will be sent to your printer.
  • Every time you push the "mode" button, one line of data will be sent to your printer.

• Interpreting RF303RS Fluctuating Readings
  • The model RF303RS incorporates an accurate digital measuring system that has three modes. The first measurement mode (default mode) utilizes a relatively short sampling time and does not filter or average ESU output. The two selectable measurement modes utilize longer sampling times that tend to average ESU output. When using the default measurement mode, you may observe some electrosurgery units (ESU) output readings that fluctuate plus or minus 10% or more depending on the unit under test. This is normal operation and is not indicative of a problem with the RF303RS.
• Determining if the ESU is the Problem
  • When fluctuating readings are observed with the RF303RS, the technician should take note and determine if this is normal behavior for the ESU under test, or if this behavior is a sign of a problem.
• It May be Normal
  • If a fluctuating output is normal for a particular ESU (as determined by the manufacturer, see accuracy specifications for ESU), the user can calculate the average of the high and low reading observed on the RF303RS (fluctuating readings may be discernable on the RF303 display) or the user can utilize the RF303RS's Signal Averaging Mode (SAM).
  • Older ESUs may have unstable output due to old technology or design. This is typical and is acceptable based on the manufacturer's limits.
  • Many newer-generation ESUs utilize instantaneous feedback loops, which constantly adjust the output and can cause an oscillating effect. This is also satisfactory and is considered normal for these devices.
• It May be Broken
  • In some cases, fluctuating ESU power output is evidence of a problem. Fluctuating output on some ESUs may indicate the weakening of output from power transistors or other ESU ailments and is not acceptable.
• Signal Averaging Measurement (SAM)
  • If an ESU normally has fluctuating output, then operating the RF303RS in one of its Signal Averaging Measurement (SAM) modes makes sense. SAM significantly reduces fluctuating readings on the display of the RF303RS making it easy for the technician to read an average value.
  • Upon power up the RF303RS defaults to the instantaneous algorithm for power output measurement which shows fluctuating ESU output. The user can select SAM by depressing the "mode select" and "- ohm select" keys simultaneously; each time the user initiates this key sequence the RF303RS will increment to the next mode, displaying "F X" momentarily. Starting at the default mode ("F 0"), the first mode entered is the one second sampling mode, ("F 1"); initiating the key sequence again will select the two second sampling mode ("F 2"), initiating the key sequence again brings the unit back to the default instantaneous mode and so on.
• Bottom Line
  • If you observe fluctuating power readings on the RF303RS, it is likely that the ESU being tested has a fluctuating output signal. To obtain an average power reading, select the RF303RS's signal averaging mode.

1. All the data must be divided by 10 except for air-flow data
2. Air flow data must be divided by 100.
3. The character "M" preceding the value indicates an event marker. This character must be suppressed from the all data to obtain a numeric value.

1. Increase the length of tubing connecting your infusion pump and the IDA 4 Plus inlet. This may act to "cushion" the effect of the occlusion of the IDA 4 Plus inlet.
2. Check that your tubing has no kinks or sharp bends, and that the tubing interior diameter is at least 1/8".
3. Check that the drain receptacle is placed lower than the IDA 4 Plus.
4. If the above steps fail, try testing a different (same model) infusion pump. If the problem persists, it may be necessary to test at a lower flow rate.

• To zero the DPM-III, set the pressure Selector Switch to the pressure range to be measured, then make sure that the DPM-III is vented to atmosphere (room air), and turn the front panel Zero Knob so that the display reads zero pressure. (NOTE: the DPM-III may take a few seconds to settle to zero when first turned ON).
• If the DPM 3 display is stable when the unit is vented, but drifts when it is connected to your pressure/vacuum source, then the problem may be caused by fluctuations in the tubing being used to connect your pressure source to the DPM 3. Avoid use of surgical tubing that can expand and contract with pressure fluctuations. Drift can also be caused by temperature fluctuations in a closed pneumatic system. Use of a three-way Luer-Lok stopcock at the DPM 3 inlet provides a convenient way of venting the DPM 3 and releasing any built-up pressure or vacuum.
• Another possible cause is that the drift may originate in the device being measured. If possible, substitute a known-good pressure source. Doing so may help you determine where the problem is.
• Excessive drift is occasionally a symptom of transducer contamination. Saline or mineral deposits, or a small piece of debris, can lodge itself inside the pressure transducer. If your DPM 3 drifts more than one or two counts when it is vented, you may have debris in the transducer. This becomes more likely if you're using hard tap water or saline during your measurements. You can try to dislodge the debris by irrigating the transducer assembly. This possibility becomes more likely with an older unit
  1. Fill a syringe (30 mL or so) with distilled water.
  2. Connect a piece of tubing to the syringe end. Use tubing small enough to be easily inserted into the DPM 3 inlet port.
  3. Insert tubing ½" or so into the DPM 3 pressure inlet; gently irrigate.
  4. Empty the syringe into the DPM 3. Hopefully, when the water exits the transducer assembly, the offending debris will be removed with it.
