AC Voltage Measurements
Warning:
Observe all safety precautions when working on live
voltages.
1. Touch the test probes in parallel to the circuit under test.
2. When the tester is measuring AC voltage, both AC voltage indicators
will be illuminated.
3. The top of the tester is marked AC on the left and DC on the right.
When the AC voltage indicators are illuminated, use the AC voltage scale
increments.
4. The approximate AC voltage is the number on the AC voltage scale that
corresponds to the top-most LED that is illuminated.
5. When the voltage tester first detects voltage, it may pause briefly at
normal operation.
6. In the figure below, both LED voltage indicators are illuminated
