16.0 Pacer Test
Tools Needed

: QED 6 Defibrillator Analyzer.
Note: The following tests are to be performed only on E Series units equipped with the optional pacing function.
The pacer output can be measured using an oscilloscope set to DC coupling connected across a load resistor. (See diagram in column for universal cable
connector polarity.) The load resistor is a 100 ohm, 5 watt or greater. The pacer output is a positive going pulse, 40 +/- 2 ms duration with an amplitude of
0.1 volt per milliamp of selected output (e.g., 40 milliamps of selected output has an amplitude of 4 +/- 0.5 volts the specified tolerance displayed on the
oscilloscope).
If an external non-invasive pacer analyzer is being used, then follow the manufacturer’s guidelines for measuring the frequency (ppm), output (mA) and
the pulse width measured in milliseconds. Note that the analyzer pace load resistor must be less than 250 ohms.
Test Setup:
Connect the universal cable from the E Series to the QED 6 Defibrillator Analyzer.
Do this... Verify that... Pass/Fail
16.1 Turn the Main Selector knob of the unit to Pacer
Mode.Set the PACER OUTPUT to 14 mA and
disconnect MFC connector from the QED 6
analyzer. The unit displays the CHECK PADS and POOR PAD CONTACT messages
displays, and the pace alarm is active. o o
16.2 Reconnect the universal cable to the QED 6
analyzer. Press Clear Pace Alarm softkey.
CHECK PADS and POOR PAD CONTACT message disappears. The pace
alarm is cleared. o o
16.3 Set rate to 180 ppm; output to 0mA. No output appears on the QED 6 analyzer. o o
16.4 Increase the output to 120mA. Output on the QED 6 analyzer is 120mA +/- 6mA. o o
16.5 Increase the output to 140mA. Output on the QED 6 analyzer is 140mA +/- 7 mA. o o
