(1)
Rotate the rotary switch to
.
(2)
Test the NCV function on a known live circuit before use.
(3)
Place the top of the meter very close to the voltage source as shown in the figure.
(4)
If voltage is detected, the LED above the display will flash, and the meter will beep.
Measuring DC or AC Current
Warning: Never attempt an in-circuit current measurement where the
open-circuit potential to earth is greater than 250 V. Doing so will
cause damage to the multimeter and possible electric shock or
personal injury.
Caution:
To avoid possible damage to the multimeter or to the equipment under
test, check the multimeter’s fuse before measuring current. Use the
proper terminals, function, and range for your measurement.
Never place the test leads in parallel with any circuit or component when
the leads are plugged into the current terminals.
(1)
Turn off the power of the measured circuit. Discharge all high- voltage capacitors.
(2)
Connect the black test lead to the
terminal.
For currents below 600 mA, connect the red test lead to the
terminal;
for currents within 600 mA – 10 A, connect the red test lead to the
terminal.
(3)
Rotate the rotary switch to the appropriate position according to the measurement
range,
,
,
or
.
(4)
Disconnect the circuit path to be tested. Connect the test leads. Reversing the leads
will produce a negative reading, but will not damage the multimeter.
(5)
Select DC or AC measurement mode. Default is DC measurement mode,
will be
displayed. Press
to switch into AC measurement mode,
will be
displayed.
(6)
Turn on the power of the measured circuit, and read the display. If necessary press
to enable and cycle through the manual ranges. If "
OL
" is displayed, it
indicates the input exceeds the selected range and the rotary switch should be set to
the position with higher range.
(7)
Turn off the power of the measured circuit and discharge all high-voltage capacitors.
Remove the test leads and restore the circuit to the original condition.
Note:
When measuring AC current, press
to cycle through frequency
measuring, duty cycle measuring, and original measuring.
