1. Utilizing TM1018 Accelerometer Verification Meter (Figure 12), cable 

conductivity, sensor location and proper wiring connections can be verified. 
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.  

 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 

2.  

One method of confirming the correct Measurement Location and proper 

cable hook up utilizes two personnel, an Accelerometer Verification Meter, 
and a means of communication (i.e. hand-held walkie-talkies if the sensors 
are not located within site of the junction box). Person A will be located @ the 
Switch Box, while Person B goes to each Measurement Location. 

a.  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 
location. A “NORMAL” LED reading should be observed. 

b.  Then Person B disconnects the cable from the accelerometer, and 

the TM1018 should respond with an “OPEN” LED. 

c.  Then Person B reconnects the cable to the accelerometer, and the 

TM1018 should respond with a “NORMAL” LED. 

d.  Repeat for each measurement location to verify that accelerometer 

location properly identified at the switch box. 

 
The following LED Readout indicates the circuit integrity: 

- 

Normal. Indicates proper connection and an output bias will be 

given, indicating the health of the sensor (4 – 16 V indicates a 
healthy accelerometer). 

 

- Open Circuit. Indicates one of the following: 

a. Cable connector is not connected to accelerometer 
b. Cable is open circuit (broken or not connected @ one end) 
c. Accelerometer is not functioning correctly.
