8.6 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 resistance (Ω) position and
ensure that the power to the circuit under test is off.
2. Press the "SEL" button to select the resistance (Ω) measurement function.
3. Connect the black lead to the COM probe socket and the red lead to the input probe
socket.
4. The measured 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.
8.7 CAPACITANCE MEASUREMENT:
Warning
Risk of electric shock.
To avoid electrical shock, the capacitor should be fully discharged before measuring.
1. Rotate the measurement function selection dial to the capacitance ( ) position, and
ensure that the power is cut off to the circuit under test.
2. Press the "SEL" button to select the capacitance ( ) measurement.
3. Connect the black test lead to the COM probe socket and the red test lead to the
INPUT probe socket.
Note: The measured value is read from the LCD.
A. When measuring large capacitance it can take a short time for a stable reading.
8.8 CONTINUITY MEASUREMENT:
Warning
Risk of electric shock.
Make sure the circuit power is off, and the circuit capacitors completely discharged.
1. Rotate the measurement function selection dial to the continuity ( ) measurement
position.
2. Press the "SEL" button to select the continuity ( ) measurement function.
3. Connect the black test lead to the COM probe socket and the red test lead to the
INPUT probe socket.
4. If the measured resistance is less than 50Ω ,the buzzer will sound.
