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

DC voltage measurements
CAUTION: Do not measure DC voltages
if a motor on the circuit is being switched
ON or OFF. Large voltage surges may
occur that can damage the meter.

V position
2. Insert the black test lead banana plug
Into the negative COM jack
3. Insert the red test lead banana plug
into the positive V jack
