8.7 AC VOLTAGE MEASUREMENT
Warning
Risk of electric shock.
When measuring high voltage, extra care should be taken to avoid electrical shock.
Do not attempt to use this meter on a voltage higher than the AC600V rms value.
1. Rotate the measurement function selection dial to the AC voltage measurement.
2. Connect the black lead to the COM probe socket and the red lead to the
INPUT probe
socket.
3. The measured value is read from the LCD.
8.8 RESISTANCE MEASUREMENT
Warning
Risk of electric shock.
When measuring the impedance on the line, make sure that the circuit power is off
and the capacitors on the circuit are fully discharged.
1. Rotate the measurement function selection dial to the Ω position and ensure that the
power to the circuit under test is off.
2. Connect the black lead to the COM probe socket and the red lead to the INPUT probe
socket.
3. The measured resistance value is read from the LCD
Note: When there is no input (e.g. open circuit), the display will show "OL" indicating that
the measured value is out of range. If the measured resistance is greater than 1MΩ, it may
take a few seconds for the meter to stabilize the reading. This is normal for high impedance
measurements.
8.9 CONTINUITY / DIODE TEST
Warning
Risk of electric shock.
Make sure the circuit power is off, and the circuit capacitors are completely
discharged.
1. Rotate the measuring function selector dial to the continuity position and ensure
that the power to the circuit under test is off.
2. Connect the lead to the COM input jack and red lead to the INPUT probe socket.
3. If the measured resistance of the line is less than 50Ω, the buzzer will sound.
8.10 HOLDING READINGS
1. Press the “HOLD” button to hold the reading while taking a measurement, the value will
be held on the display “ H ”.
2. Press the “HOLD” button again to return to the normal reading function.
