LVDT Output

Zero adjustment (if required)

1. Connect a voltmeter across the LVDT green and yellow (or yellow and white; hazardous

LVDT) wires.

2. With no load applied to the sensing plate, observe the V AC reading on the voltmeter.

3. If the LVDT output is 0.10 ± 0.05 V AC, skip to Span Test, otherwise, proceed as follows:

– Loosen the locknut on the LVDT threaded core.

– Turn the core in/out of the LVDT until 0.10 ± 0.05 V AC is obtained.

– Tighten the locknut, ensuring the measured value is maintained.
