IV. Measuring Instruction:
4.1 ACA
、
ACmA measurement:
1.Set the range selector switch to the desired position current to
measure should be within the selected measuring rang.
2.Normal measurement (see Fig.1):
Press the jaw trigger to open the transformer jaws and close them
over one conductor only. Measured current value is shown on the
display. Earth leakage current or small current that flows through a
grounded wire can also be measured by this method.
3.Measuring out of balance leakage current (see Fig.2):
Clamp onto all conductors except a grounded wire, measured current
value is shown on the display.
Before this measurement, disconnect any test lead with the meter for
safety.
In some cases where reading is difficult, press the HOLD button and
read the result later.
