ECG Calibration
Tool required:
Vernier caliper
Follow this procedure to perform a calibration:
1. Select the ECG parameter window or waveform area→ [Filter]→ [Diagnostic].
2. Select [Main Menu]→ [Maintenance>>].
3. Select [Calibrate ECG]. A square wave appears on the screen and the message [ECG
Calibrating] is displayed.
4. Compare the amplitude of the square wave with the wave scale. The difference should
be within 5%.
5. After completing the calibration, select [Stop Calibrating ECG].
If necessary, you can print out the square wave and wave scale through the recorder and then
measure the difference.
3.4.2 Resp Performance Test
Tool required:
Fluke Medsim 300B patient simulator recommended
Follow this procedure to perform the test:
1. Connect the patient simulator to the module using a non ESU-proof cable and set lead II
as the respiration lead.
2. Configure the simulator as follows: lead II as the respiration lead, base impedance line
as 1500 Ω; delta impedance as 0.5 Ω, respiration rate as 40 rpm.
3. Check the Resp wave is displayed without any distortion and the displayed Resp value is
within 40 ± 2 rpm.
