AC & DC VOLTAGE MEASUREMENT
Do not measure AC/DC voltages if a motor on the circuit is being
switched on or off. Large voltage surges may occur that can damage the
meter.
1) Insert the black test lead into the negative COM input jack.
2) Insert the red test lead into the positive V input jack.
3) Set the function switch to the VAC or VDC position.
4) Connect the test leads in parallel to the circuit under test.
5) Read the voltage measurement displayed on the LCD screen.
AC & DC CURRENT MEASUREMENT
Use the proper terminals, function and range for any current
measurement.
1) Set the function switch:
• For current measurements up to 2000µA AC/DC, set the function switch
to the mA position.
• If the range of the measured current is not known, select the higher
range first, then move to the lower range if necessary.
2) Insert the black test lead into the negative COM input jack.
3) Insert the red test lead into the positive V input jack.
4) Press the mode button to select AC or DC measurement.
5) Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
6) Touch the black test probe tip to the negative side of the circuit and
touch the red test probe tip to the positive side.
7) Apply power to the circuit.
8) Read the measurements displayed on the screen.
Function Switch Select a measurement range by turning the
switch to the preferred option.
