Biomed Check

Hi Alex,  The procedure is in the service manual of whichever MP/MX monitor you are using.  It doesn't require a simulator or special cable:

NMT Stimulation Output Test

1 Short circuit the stimulation cables by connecting the two cable clamps to each other as shown below.

2 In service mode, select the Setup NMT menu.

3 Select Start Test.

4 Select Confirm.

Test Expected test results -

NMT Stimulation Output Test passed is displayed on the monitor

NMT Transducer Test

1 Go into Service Mode. In Service Mode the NMT Bar Graph only contains three bars instead of four.

2 Place the NMT Transducer on a flat surface with the flat side facing downwards. Two of the three bars in the NMT bar graph should be at the same level and the third one should be higher than the other two.

3 Turn the NMT Transducer 180° and place it on a flat surface with the flat side facing upwards. The bar that was higher than the other two before should now be lower than the other two by approximately the same amount.

Expected test results -

NMT Transducer Test First two bars in the NMT bar graph are at the same level, third bar is higher when the flat side of the transducer is facing downwards and lower by the same amount when the
transducer is facing upwards.
