Operation
NOTICES
: Read and understand all
warning
and
precaution
statements listed in the
safety section of this operation manual prior to using this meter. Set the function
select switch to the OFF position when the meter is not in use.
DC/AC Current Measurements
WARNING:
Ensure that the test leads are
disconnected from the meter before making current
clamp measurements.
1. Set the Function switch to the
1000A or400A or
40A
range. If the range of the measured is not known,
select the higher range first then move to the lower
range if necessary.
2. Select AC or DC with the
MODE
button.
3. Press the trigger to open jaw. Fully enclose one
conductor
to be measured.
4. The clamp meter LCD will display the reading.
DC/AC Voltage Measurements
1. Insert the black test lead into the negative
COM
terminal and the
red test lead into the positive
V
terminal.
2. Set the function switch to the V position.
3. Select AC or DC with the
MODE
button.
4. Connect the test leads in parallel to the circuit under test.
5. Read the voltage measurement on the LCD display.
