WARNING!
Electric shock can cause DEATH or SEVERE PERSONAL INJURY.
Always observe the following precautions when working:
1. Never touch exposed conductors of electricity with fingers, hands or any
other body part.
2. Use caution when working near voltages above 30 VAC rms, 42 VAC peak,
or 60 VDC. Voltages this high present a risk of electric shock.
3. Disconnect the circuit’s power before connecting the meter in series, when
measuring current.
4. Connect the common (COM) test lead first and disconnect it last.
5. Hold the probes with fingers behind guards.
Operation
DC Voltage Measurements
Measure DC voltages up to 1,000 V.
1. Turn the Range Selector Switch to 1000 DCV.
Always start with the highest range
if the voltage is unknown.
2. Plug the red lead into the + Jack.
Plug the black lead into the -Com
Jack.
3. Carefully touch the appropriate ex-
posed conductors with the tips of the
probes to measure the voltage (not
amperes).
4. Read measurement on the Volt/Amp
Scale - see
How to Read the Volt/
Amp Scale
table, right.
If the needle moves in the opposite
direction, then the probes are con-
nected incorrectly. Reverse the
probes’ locations.
If the voltage is less than 500 volts,
set the Range Selector Switch to the
next lower range until the meter
pointer is mid-range on the scale.
