If the front tractor is not installed, threshold values written in NVRAM display:
T&D15 Sensor Test Rear: x1 PRESS A KEY
where:
v x1 is the threshold for the rear tractor
v x1 is a numbers in hexadecimal format, which correspond to the measured voltages, resolution of 20 mV.
Press any key to go to step 8.
8. The following displays:
T&D15 Sensor Test SENSOR LEVEL ? YES ... NO
This part of the test is intended for use by Product Engineering, and allows the user to examine sensor
output voltages.
9. Press the Start key to skip to step 10 on page 122.
Press the Line Feed key to enter.
If the front tractor is installed, the current sensor measurements display:
T&D15 Sensor Test Rear: x1 Front: x2 PRESS A KEY
where:
v x1 is rear (base) path measurement
v x2 is front (second or optional) path measurement
v x1, x2 are numbers in hexadecimal format, which correspond to the measured voltages, resolution of 20
mV.
The display continuously updates to track sensor output changes.
