Module, E-NMT or M-NMT.
Start Curr. test is a test where the module itself
checks the difference between a given current and
the measured current. A 3 kΩ resistance should be
connected between the stimulus electrodes before
starting the test. All the currents checked will be
displayed on the service data screen. After the
current value, the status of the test is shown. If the
test is not passed, send the module back to the
factory for calibration.
T1%/ref T1% / ref gives a selection for changing
settings related to the NMT MechanoSensor. A setting
of 3 should always be used for normal monitoring.
The settings 1 and 2 are for research purposes only.
Record Data prints out the displayed service data
and circuit board information (id., serial number, and
software id.) on the recorder.
Service Data
Cable shows the type of cable being used.
Cable check value shows the bit amount. To check the value for each cable, see the following chart:
- EMG -100...+100
- Cable OFF >1950
- Piezo 900...1100
- Regional block 600....800
Module keys checks the function of the module keys. A blue background appears at the back of the text
when a key is pressed for more than one second.
Stimulus mode shows the selected stimulus. Stimulus mode can be changed using the NMT Setup menu.
Measurement indicates ON/OFF.
T1%, T2% shows the measured response. A value of 1000 corresponds to 100%.
Absolute T1, T2 shows the voltage measured from the A/D converter.
Noise indicates the interference just before the measurement. A typical value is <100.
Offset is an average of the noise measurement. A typical value is 510.
Curr set is the selected current, a value of 700 corresponds to 70 mA.
Curr meas is the measured current, a value of 700 corresponds to 70 mA.
Pulses indicates pulses the module has produced.
Piezo probe T1% and Ref. search shows information related to the MechanoSensor settings.
