will be turned on. Press the button again to turn the
backlight off. If the button is not pressed again then the
backlight will be automatically turned off in about 30
seconds after it's turned on.
6. MEASURING INSTRUCTION
6-1 ACA, ACmA Measurement:
(1) Set the range selector switch to the desired position.
The current to be measured should be within the
measuring range.
(2) Normal measurement (see Fig. 1):
Using the trigger, open the clamp meter jaw and clamp
around the conductor. Make sure that the conductor
is positioned in the center and that the flow of current
matches the arrows located on the jaws of the clamp meter.
The display will show the value of the measurement being
taken. Earth leakage current or any small AC current that
flows through a ground wire can also be measured
by this method.
NOTE: Keeping the cable in the center of the clamp will
return more accurate test results when making current
measurements. Zero meter to accurately measure low
milliamp circuits.
(3) Measuring out of balance leakage current (see Fig. 2):
Disconnect the test leads from the meter. Clamp the
jaw around all conductors except the ground wire. The
measured imbalance current value is shown on the display.
If the display is not giving a steady and consistent reading,
press the HOLD button and read the display after the
clamp is removed from the conductors.
