Warning!
Risk of electrocution. High voltage circuits, both AC and dC are dangerous and should be measured with great care.
Always turn the function switch to the off position when the meter is not in use.

aC/dC Voltage measurements
8
do not
measure dC/AC voltages if a motor on the circuit is being switched on or oFF. large voltage surges may occur that can
damage the meter.
4.1.1.
Set the function switch to the green V position.
4.1.2.
Press the mode button to indicate “dC” or “AC” on the display.
4.1.3.
Touch the black test probe tip to the negative side of the circuit.
4.1.4.
Touch the red test probe tip to the positive side of the circuit.
4.1.5.
Read the voltage in the display.
4.2.
dC/aC Current measurements
4.2.1.
Set the function switch to the µA/mA position.
4.2.2.
For current measurements up to 2000uA dC/AC, set the function switch to the mA position
4.2.3.
Press the mode button to indicate “dC” / “AC” on the display.
4.2.4.
Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.
4.2.5.
Touch the black test probe tip to the negative side of the circuit.
4.2.6.
Touch the red test probe tip to the positive side of the circuit.
4.2.7.
Apply power to the circuit.
4.2.8..
Read the current in the display.
4.3.
resistanCe measurement
Warning!
To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any
resistance measurements. Remove the batteries and unplug the line cords.
4.3.1.

position.
4.3.2.
.
Press.the.MODE.button.to.indicate.Ω.on.the.display.
4.3.3.
Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the
circuit will not interfere with the resistance reading.
4.3.4.
Read the resistance in the display.
4.4.
Continuity CHeCK
Warning!
To avoid electric shock, never measure continuity on circuits or wires that have voltage on them.
4.4.1.
..
Set.the.function.switch.to.the.Ω..........position.
4.4.2.
Press the mode button to indicate on the display
4.4.3.
Touch the test probe tips to the circuit or wire you wish to check.
4.4.4.

4.5.1.
..
Set.the.function.switch.to.the.Ω..........position.
4.5.2.
Press the mode button to indicate on the display.
4.5.3.
Touch the test probes to the diode under test. Forward voltage will typically indicate 0.400 to 0.700V. Reverse voltage will indicate
“ol”. Shorted devices will indicate near 0V and an open device will indicate “ol” in both polarities.
4.6.
non-Contact aC Voltage measurements
Warning!
Risk of electrocution. Before use, always test the Voltage detector on a known live circuit to verify proper operation
4.6.1.
.
Position.the.non.contact.probe.fig.1.1..in.close.proximity.to.the.cable/conductor.
4.6.2.
If AC voltage is present, the detector light will illuminate.
note:
The conductors in electrical cables are often twisted. For best results, move the non contact probe along a length of the
cable to assure the probe is in close proximity to the live conductor.
note:
The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly operate the sensor.
This is normal operation.
