J WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, J 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.
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.
DC VOLTAGE MEASUREMENTS
J AUTION: 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.
1. Set the function switch to the highest V DC _---
position
2. Insert the black test lead banana plug into the _ I
negative (COM) jack. • ................
Insert the red test lead banana plug into the _')i,
positive (V) jack.
3. Touch the black test probe tip to the negative side _/i
of the circuit. /_j _t'_/.
Touch the red test probe tip to the positive side of .......
the circuit.
4. Read the voltage in the display. Reset the
function switch to successively lower V DC
positions to obtain a higher resolution reading.
The display will indicate the proper decimal point and value. If the
polarity is reversed, the display will show (-) minus before the value.
