Service Manual
Heart Rate
1. Set the ECG simulator to ECG QRS Waveform. Set the rate to 251 bpm.
2. Verify the Rate display is 251 ± 5 bpm.
3. Decrease the rate to 30 bpm and allow signal to stabilize. Verify that the rate display is
30 bpm ± 3 bpm.
Alarms
1. Set the simulator to 1mv ECG QRS signal, rate set to 60 bpm
2. Set to Print on Alarm, install paper in the recorder, and set the Low HR alarm to 50
bpm, and High alarm to 120 bpm.
3. Increase the HR to 125 and verify the following:
a. The high alarm violates with an audio tone and red LED on keypad.
b. The recorder is initiated and prints the ECG strip displaying the ECG information.
c. Verify the overall width of the grid is 40 mm ± 2 cm.
d. Mute the alarm by pressing the MUTE ALL key.
e. Verify that the Mute Alarm message is displayed in the Message Area “A” and the
alarm is silent.
4. Press the MARK EVENT key. Press the TREND key and examine the trend data. The
high HR rate should be red (LCD) indicating the High HR was violated.
4.6.3 IBP 1, IBP 2, IBP 3 and IBP 4 (Optional) Verification
1. Set the simulator to 0 mmHg for both IBP 1 and IBP2.
2. Press the ZERO ALL key. Verify the systolic, diastolic and mean values display as 0 ±
1mm /Hg.
3. Apply 50,150, and 300 mmHg and verify that Sys/ Dia /Mean parameters agree.
4. Apply a 120/80/mmHg signal into IBP - 1 and 3 apply a 60 / 20/ mmHg signal into
IBP 2 and 4 and verify that the correct waveforms are displayed on the screen.
4.6.4 Temperature Verification
400 Series Probe
1. Set the Simulator to 37° C. Connect to the monitor using a 400 series probe.
2. Verify the temperature is 37° ± 2°C.
700 Series Probe
1. Repeat same test for 700 series probe.
