Measuring AC or DC Voltage
Warning: Do not measure any voltage of over 1000 Vdc or 750 Vac rms to
avoid instrument damage or electric shock.
Do not apply more than 1000 Vdc or 750 Vac rms between the
common terminal and the earth ground to avoid instrument damage
or electric shock.
This multimeter displays DC voltage values as well as their polarity. Negative DC voltages
will display a negative sign on the left of the display.
(1)
Rotate the rotary switch to
. Default is DC measurement mode,
will be
displayed. Press
to switch into AC measurement mode,
will be displayed.
(2)
Connect the black test lead to the
terminal and the red test lead to the
terminal.
(3)
Probe the test points and read the display. Press
to enable and cycle through
the manual ranges.
Note:
When measuring AC voltage, press
to cycle through frequency measuring,
duty cycle measuring, and original measuring.
Measuring Resistance
Caution:
To avoid possible damage to your multimeter or to the equipment under
test, disconnect the circuit power and discharge all high-voltage
capacitors before measuring resistance.
(1)
Rotate the rotary switch to
.
(2)
Connect the black test lead to the
terminal and the red test lead to the
terminal.
(3)
Probe the test points and read the display. Press
