Operation
AC Current Measurements
*NOTE:
Ensure that the test leads are disconnected from the meter before
making current clamp measurements.*
1.
Set the Function switch to the AC Current.
2.
Place the current open jaw around the middle of the test lead.
3.
The clamp meter LCD will display the reading.
AC (True RMS)/DC Voltage Measurements
1.
Insert the black test lead into the negative
COM
terminal and the red test
lead into the positive
V Ω CAP
terminal.
2.
Automatically change between AC or DC.
3.
Connect the test leads in parallel to the circuit under test.
4.
Read the voltage measurement on the LCD display.
Low Z Voltage Measurements
*NOTE
:
Observe all safety precautions when working on live voltage. Do not connect
to circuits that exceed 600V AC/DC when the meter is set to Low Z.
Low Z is used when there is a suspicion of a “ghost” voltage. Ghost voltages are
present when non-powered wires are in close proximity to wires powered by AC
voltage. Capacitive coupling between wires make it appear that non-powered wires are
connected to a real source of voltage.
The Low Z setting places a load on the circuit, which dissipates and greatly reduces
ghost voltage.
1.
Set the rotary function switch to the Low Z position.
2.
Momentarily press the MODE button to select AC or DC voltage. The AC
or DC symbol will appear on the LCD display.
3.
Insert the black test lead into the COM input jack and the red test lead
into the V input jack. If measuring DC voltage, touch the red test lead to
the positive side of the circuit and the black test lead to the negative side
of the circuit.
