DC Voltage Measurement
1. connect the black test lead to the cOM socket, and the red test lead to the red v
Ω
socket.
2. Turn the function switch to v .
3. connect the test leads and check the reading.
AC Voltage Measurement
1. connect the black test lead to the cOM socket, and the red test lead to the red v
Ω
socket.
2. Turn the function switch to v .
3. connect the test leads and check the reading.
AC Current Measurement
1. Disconnect any test leads connected to the meter.
2. set the selector switch to desired ”2a/20a~” or ”200a/1000a~” position.
3. Open the clamp by pressing the jaw-opening handle and insert the cable to be measured into the jaw.
Measure only one cable at the time.
4. close the clamp and check the reading from the LcD display.
Resistance Measurement
1. connect the black test lead to ”cOM” socket and red test leads to the ”v
Ω
” socket.
2. set the selector switch to “
Ω
” position.
3. connect and check the reading.
caution: Ensure that the circuit to be tested is voltage free. Max. input overload: 250v rms. and <10 sec.
Diode, Continuity Test
1. connect the black test lead to “cOM” socket and red test leads to the “v
Ω
” socket.
2. set the selector switch to ”
” position and press ”sEL” key to choose function.
3. connect and check the reading.
caution: Ensure that the circuit to be tested is ”dead”. Max. input overload: 250v rms. and <10 sec.
