Post Installation Testing
The TM1018 Accelerometer Verification Meter can be used to verify cable
conductivity, sensor location and proper wiring connections . The Verification
Meter will indicate if the sensor, cable and/or junction box is in working condition .
It will also confirm bias voltage of the accelerometer, which will inform you of the
operation of the internal accelerometer amplifier .
Testing Method:
1 . Utilizing two personnel, Person A will be located at the switch box, while Person
B will be located at the measurement location .
2 . Once positioned, Person A will connect the TM1018 to the data collector output
to the switch box and turn the Channel Selector to the channel that corresponds
to the referenced measurement . Person A should observe a “NORMAL” LED
reading .
3 . Person B disconnects the cable from the accelerometer, and the TM1018 should
respond with an “OPEN” LED . Reconnect the cable to the accelerometer, and
the TM1018 should respond with a “NORMAL” LED .
4 . Repeat for each measurement location to verify that accelerometer location is
properly identified at the switch box .
