3. OPERATION
3.1 DC and AC Voltage Measurement
1) Connect the black test lead to “COM” socket and
red test lead to the “VÙHz” socket.
2) Set the selector switch to desired “mV ~” or “V~”
position,
3) Press “SELECT” key to choose “DC” or “AC”
measurement
4) Measure the voltage by touch the test lead tips to
the test circuit where the value of voltage is needed.
5) Read the result from the LCD panel.
3.2 DC Current Measurement
1) Set the selector switch to desired “400A~” or
“3000A~”position .
2) Press “SELECT” key to choose “DC”
measurement.
3) Zero the reading by pressing “RELr
” key for a
reading of zero on the display.
4) Disconnect the test leads from the meter.
5) Clamp the Jaws around the one conductor to be
measured. Center the conductor within the Jaw
using the Centering Marks as guides.
6) Read the result from the LCD panel. The arrow in
the Jaw indicates the direction of positive current
flow (positive to negative )
