2. Enfòmasyon sou Sekirite

WARNING: Read and understand all safety information and operating instructions before using this instrument. Failure to follow these instructions could result in severe injury or death.

• Always adhere to local and national safety regulations.
• Do not use the multimeter if it appears damaged or if the insulation on the test leads is compromised.
• Asire w ke ou chwazi fonksyon ak ranje ki kòrèk la anvan ou fè nenpòt mezi.
• Pa depase limit maksimòm opinyon yo pou okenn fonksyon.
• Fè atansyon lè w ap travay ak volimtages above 30 V AC RMS, 42 V AC peak, or 60 V DC, as these pose a shock hazard.
• Always disconnect the test leads from the circuit before changing the function switch.
• Ranplase pil yo lè endikatè pil fèb la parèt pou asire lekti yo egzak.
• The device is rated CAT IV 300 V and CAT III 600 V. Understand these categories and use the meter only in appropriate environments.

4. Pwodwi souview

The BENNING CM 2-1 features a compact design with a clear digital display, a rotary function switch, and control buttons for various measurement modes.

4.1. Kontwòl ak Ekspozisyon

• Clamp Machwa: For non-contact AC/DC current measurement.
• Rotary switch: Selects measurement functions (OFF, LoZ, AutoV, V~, V-, Hz, Ω, A~, A-).
• HOLD/MIN MAX Button: Freezes the current reading or displays minimum/maximum values.
• AC/DC HFR/ZERO Button: Toggles between AC/DC current, activates the low pass filter (HFR), or zeros the DC current reading.
• Ekspozisyon: Digital readout for measurement values, units, and indicators.
• Input Jacks (COM, VΩ): Pou konekte fil tès pou volimtage, resistance, and other measurements.

5. Enstalasyon

5.1. Enstalasyon batri

The BENNING CM 2-1 requires 2 AAA batteries. These are typically included with the device.

1. Asire w ke miltimèt la etenn.
2. Jwenn konpatiman batri a sou dèyè aparèy la.
3. Sèvi ak yon tournevis pou ouvri kouvèti konpatiman batri a.
4. Mete 2 pil AAA yo nan plas yo, epi obsève polarite ki kòrèk la (+/-) jan yo endike anndan konpatiman an.
5. Ranplase kouvèti lòj batri a epi an sekirite li ak vis la.

6. Operasyon Enstriksyon

6.1. AC/DC Current Measurement (Clamp)

To measure AC or DC current without breaking the circuit:

1. Turn the rotary switch to the “A~” or “A-” position.
2. Press the AC/DC HFR/ZERO button to select AC or DC current if necessary. For DC current, press and hold to zero the display before measurement.
3. Louvri cl laamp jaw and enclose a single conductor. Ensure the jaw is fully closed.
4. Li valè aktyèl la sou ekran an.

6.2. AC/DC Voltage Mezi

Pou mezire AC oswa DC voltage:

1. Insert the red test lead into the VΩ jack and the black test lead into the COM jack.
2. Turn the rotary switch to the “V~” for AC voltage or “V-” for DC voltage.
3. Konekte sond tès yo atravè sikwi a oswa konpozan ki pral mezire a.
4. Li voltage valè sou ekspozisyon an.

6.3. AutoV Function (LoZ)

The AutoV function with low input impedance (LoZ) helps to suppress 'ghost voltages' or 'reactive voltages' that can appear on unused wires or open circuits due to capacitive coupling. To use:

1. Insert the red test lead into the VΩ jack and the black test lead into the COM jack.
2. Turn the rotary switch to the “LoZ” position. The meter will automatically detect AC or DC voltage.
3. Connect the test probes across the circuit.
4. Li voltage valè sou ekspozisyon an.

6.4. Low Pass Filter (HFR)

The HFR (High Frequency Rejection) low pass filter is used for stable and accurate measurements on variable frequency drives (VFDs) or other noisy electrical environments. To activate:

1. Select the desired AC current (A~) or AC voltage (V~) function.
2. Press and hold the AC/DC HFR/ZERO button until “HFR” appears on the display.
3. Proceed with your measurement as usual. The filter will suppress high-frequency noise components.

7. Antretyen

7.1. Netwayaj

Siye ka a ak anonsamp twal ak yon savon dou. Pa sèvi ak pwodui abrazif oswa solvang. Asire w ke aparèy la byen sèk anvan ou itilize li.

7.2. Ranplasman batri

Lè endikatè pil ki fèb la parèt sou ekran an, ranplase pil yo touswit pou asire yon fonksyònman ki kòrèk. Gade Seksyon 5.1 pou enstriksyon enstalasyon pil yo.

NAN. Depanaj

• Pa gen ekspozisyon: Tcheke enstalasyon batri a epi si l chaje. Ranplase batri yo si sa nesesè.
• Lekti ki pa kòrèk: Ensure correct function and range are selected. Check test lead connections. Verify the clamp jaw is fully closed for current measurements.
• “OL” on Display: Indicates an overload (measurement exceeds the selected range). Select a higher range or ensure the input is within the device's specifications.
• Lekti enstab: Ensure good contact with test probes. For current measurements, ensure only one conductor is within the clamp jaw. Consider using the HFR function in noisy environments.
