4. Sustituite a tappa di u compartmentu di a bateria è assicuratelu cù a vite.

4.2. Accensione iniziale

Turn the rotary switch to any measurement function (e.g., V~ for AC Voltage) to power on the device. The display will illuminate, indicating the device is ready for use.

5. Operating Instructions

The BENNING CM 12 offers a variety of measurement functions. Select the desired function using the rotary switch.

5.1. AC/DC Current Measurement (Clamp funzione)

1. Girate l'interruttore rotativu in a pusizione 'A~' (corrente AC) o 'A=' (corrente DC).
2. Press u clamp trigger to open the jaw.
3. Racchiude un unicu cunduttore cù u clamp mandibula. Assicuratevi chì a mandibula sia cumpletamente chjusa.
4. Leghjite u valore attuale nant'à u display.
5. For AC+DC True RMS measurements, ensure the appropriate mode is selected if available via the MODE button.

5.2. voltagMisurazione (AC/DC)

1. Insert the red test lead into the 'VΩ' input jack and the black test lead into the 'COM' input jack.
2. Turn the rotary switch to 'V~' (AC Voltage) o 'V=' (Volume DCtagè).
3. Cunnette i cavi di prova in parallelu à u circuitu o cumpunente sottu prova.
4. Leghjite u voltagU valore nantu à a visualizazione.

5.3. Resistance and Continuity Measurement

1. Assicuratevi chì u circuitu sia disenergizatu prima di a misurazione.
2. Insert test leads as for voltage misurazione.
3. Turn the rotary switch to 'Ω' (Resistance/Continuity).
4. Cunnette i cavi di prova à traversu u cumpunente.
5. For continuity, the meter will beep if resistance is below approximately 30Ω - 100Ω.

5.4. Test diode

1. Assicuratevi chì u circuitu sia disenergizatu.
2. Insert test leads as for voltage misurazione.
3. Turn the rotary switch to the 'Diode' symbol.
4. Cunnette u filu rossu à l'anodu è u filu neru à u catodu di u diodu. Un vulume direttutage drop (approx. 0.8V) will be displayed. Reverse the leads for an open circuit reading.

5.5. Misurazione di a currente di spuntu

This function measures the initial surge of current when a device (e.g., motor, lamp) is first turned on.

1. Turn the rotary switch to the 'A~' position.
2. Press the 'INRUSH' button (if dedicated) or activate via 'MODE' button.
3. Clamp the meter around the power conductor of the device.
4. 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.

1. Turn the rotary switch to the 'W' (Power) position.
2. Connect the test leads for voltage measurement and clamp the jaw around the current conductor.
3. The display will show active power (W) and power factor.

5.7. Data Logger Function (LOG) and Bluetooth Interface

The device features a data logger capable of storing 10,000 readings with a sampling rate from 1 second to 10 minutes. It also includes a Bluetooth interface for data connection to smartphones or tablets via the "BENNING MM-CM Link" app.

1. Download and install the "BENNING MM-CM Link" app from your device's app store (iOS and Android compatible).
2. Activate Bluetooth on your smartphone/tablet and on the BENNING CM 12 (refer to the device's specific button for Bluetooth activation, usually a dedicated button or a long press of 'MODE').
3. Pair the device with the app.
4. Use the app to configure logging parameters (sampling rate, start/stop logging) and to view/export recorded data.

5.8. Low-Pass Filter (HFR)

The HFR (High-Frequency Rejection) low-pass filter is used for accurate measurements on clocked motor drives or other noisy environments by filtering out high-frequency interference.

• Activate the HFR filter via a dedicated button or by pressing the 'MODE' button in relevant measurement functions (e.g., AC Voltage or Current).
• The display will typically show an indicator when the filter is active.

5.9. Total Harmonic Distortion (THD) Measurement

The THD function assesses network quality by measuring the total harmonic distortion of voltage or current waveforms.

• Select the THD function using the rotary switch or 'MODE' button in AC Voltage/Current modes.
• Connect the meter as appropriate for voltage o misura di corrente.
• The display will show the THD value.

5.10. Two-Pole Rotary Field Testing

This function is used to determine the phase sequence in three-phase systems.

1. Turn the rotary switch to the 'Rotary Field' symbol (if dedicated) or select via 'MODE' button in a relevant AC voltage funzione.
2. Connect the test leads to two phases of the three-phase system.
3. The display will indicate the phase sequence (e.g., L1-L2, L2-L3).

6. Mantenimentu

6.1. Pulizia

Pulisce u casu cù l'annunziuamp pannu è detergente dolce. Ùn aduprate micca abrasivi o solventi. Assicuratevi chì u dispusitivu sia spento è scollegatu da qualsiasi circuitu prima di pulisce.

6.2. Sustituzione di batterie

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Remove batteries if the device will not be used for an extended period to prevent leakage.

6.3. Storage

Store the multimeter in its carrying case in a cool, dry environment, away from direct sunlight and extreme temperatures. Remove batteries for long-term storage.
