5.3. Resistance and Continuity Measurement
- Ensure the circuit is de-energized before measurement.
- Insert test leads as for voltage inenga.
- Turn the rotary switch to 'Ω' (Resistance/Continuity).
- Honoa nga kaiarahi whakamatautau puta noa i te waahanga.
- For continuity, the meter will beep if resistance is below approximately 30Ω - 100Ω.
5.4. Whakamātautau Diode
- Me whakarite kia whakakorea te hiko o te ara iahiko.
- Insert test leads as for voltage inenga.
- Turn the rotary switch to the 'Diode' symbol.
- Connect the red lead to the anode and the black lead to the cathode of the diode. A forward voltage drop (approx. 0.8V) will be displayed. Reverse the leads for an open circuit reading.
5.5. Inrush Current Measurement
This function measures the initial surge of current when a device (e.g., motor, lamp) is first turned on.
- Turn the rotary switch to the 'A~' position.
- Press the 'INRUSH' button (if dedicated) or activate via 'MODE' button.
- Clamp the meter around the power conductor of the device.
- Turn on the device to measure the inrush current.
5.6. Power Measurement (W) and Power Factor
The BENNING CM 12 can simultaneously detect current (A) and voltage (V) to calculate active power (W) and power factor in AC/DC networks.
- Turn the rotary switch to the 'W' (Power) position.
- Connect the test leads for voltage measurement and clamp the jaw around the current conductor.
- The display will show active power (W) and power factor.
