Testing the Instrument 155
Accuracy and Performance Procedures
The following accuracy, calibration, and performance procedures are designed to be
completed to verify the accuracy and performance of the Instrument. They must be
performed once every two years and when the Instrument is repaired or when Instrument
parts are replaced.
Temperature Accuracy
This test checks the performance of the temperature parameter. The temperature accuracy test
is required once every two years.
Tools required: Patient simulator (with 0.1
o
C or 0.2
o
F)
Step 1 Connect the patient simulator to the temperature connector on the Measurement
Server or Measurement Server Extension.
Step 2 Configure the patient simulator to 40
o
C or alternatively 100
o
F
Step 3 The value should be 40
o
C ± 0.2
o
C or 100
o
F ± 0.4
o
F.
If the displayed value is not within the tolerances given above, refer to "Troubleshooting the
Instrument".
ECG/Resp Performance
This test checks the performance of the ECG and respiration parameters. ECG/Resp
performance test is required once every two years.
Tools required: Patient Simulator.
ECG Performance
Step 1 Connect the Patient Simulator to the ECG/Resp connector on the Measurement
Server.
Step 2 Configure the Patient Simulator as follows:
— ECG sinus rhythm.
— HR = 100 bpm
Step 3 Check the displayed ECG wave and HR value against the simulator configuration.
