Specification Operation

Warning:

RISK OF ELECTROCUTION. HIGH-VOLTAGE CIRCUITS,

BOTH AC AND DC, ARE VERY DANGEROUS AND

SHOULD BE MEASURED WITH GREAT CARE.

1. ALWAYS turn the function switch to the OFF position when the meter is not in use. This meter has Auto OFF that automatically shuts the meter

OFF if 15 minutes elapse between uses.

2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range.

Note:

On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading. This is normal and is caused by the high-input sensitivity.

The reading will stabilize and give a proper measurement when connected to a circuit.
