Operation

NOTES: Read and understand all Warning and Caution statements in this operation manual prior

to using this meter. Set the function select switch to the OFF position when the meter is not in use.

Input Shutter

The Input Shutter inhibits simultaneous connection to the thermocouple jacks and the DMM input

jacks. This is a safety feature which prevents a potentially hazardous condition from existing during

high voltage measurements. Slide the shutter up for test lead measurements or slide it down for

thermocouple temperature measurements.

Non-Contact Voltage Detector

WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live

circuit to verify proper operation.

1. Rotate the Function switch to any measurement position.

2. Place the detector probe tip on the conductor to be tested.

3. If AC voltage is present, the NCV detector light will turn on

with a steady red light.

NOTE: The conductors in electrical cord sets are often twisted. For

best results, move the probe tip along a length of the cord

to assure placing the tip in close proximity to the live

conductor.

NOTE: The detector is designed with high sensitivity. Static

electricity or other sources of energy may randomly trip the sensor. This is normal operation.
