4. Configurare

4.1 Instalarea bateriei

The ANENG DT3266L requires two AAA 1.5V batteries for operation. Ensure correct polarity when installing.

1. Localizați capacul compartimentului bateriei pe spatele multimetrului.
2. Folosiți o șurubelniță pentru a scoate șurubul care fixează capacul bateriei.
3. Insert two AAA 1.5V batteries, observing the polarity markings (+ and -) inside the compartment.
4. Puneți la loc capacul bateriei și fixați-l cu șurubul.

5. Instrucțiuni de utilizare

To operate the multimeter, turn the rotary switch to the desired measurement function. Connect the test leads or use the clamp jaw as appropriate for the measurement type.

5.1 Măsurarea curentului alternativ

To measure AC current, use the clamp jaw. Ensure the circuit is de-energized before clamping, if possible, or exercise extreme caution.

1. Turn the rotary switch to the '20A' or '200A' AC current range.
2. Deschide clamp maxilarului apăsând trăgaciul.
3. Enclose only one conductor (e.g., the Live wire) within the clamp maxilar. Nu închidețiamp around both Live and Neutral wires simultaneously, as this will result in an inaccurate zero reading.
4. Închide clamp jaw securely.
5. Citiți valoarea curentului alternativ pe afișajul LCD.

5.2 AC/DC Voltage Măsurare

Pentru a măsura volul AC sau DCtage, use the provided test leads.

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'VΩ' jack.
2. Turn the rotary switch to the desired ACV (e.g., '600V~') or DCV (e.g., '600V-') range.
3. Conectați sondele de testare la circuitul sau componenta care urmează să fie măsurată.
4. Citiți voltagValoarea de pe ecranul LCD.

5.3 Măsurarea rezistenței

To measure resistance, ensure the circuit is de-energized before connecting the test leads.

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'VΩ' jack.
2. Turn the rotary switch to the desired resistance range (e.g., '2KΩ', '200KΩ', '2MΩ').
3. Connect the test probes across the component whose resistance is to be measured.
4. Citiți valoarea rezistenței pe afișajul LCD.

5.4 Live Wire Identification (L LIVE)

This function helps identify live wires. Refer to the product overview for the specific 'L (LIVE)' setting on the rotary switch.

1. Turn the rotary switch to the 'L (LIVE)' position.
2. Carefully touch the red test probe to the conductor suspected of being live.
3. The meter will indicate if the wire is live, typically through an audible beep or a specific display icon.

5.5 Funcția HOLD

Press the 'HOLD' button to freeze the current reading on the LCD display. Press it again to release the hold and resume live readings.

5.6 LIGHT Function

Press the 'LIGHT' button to activate the backlight for the LCD display, improving visibility in dimly lit environments. Press it again to turn off the backlight.

6. Measurement Techniques

6.1 Correct AC Current Measurement

For accurate AC current measurement using the clamp function, ensure that only a single conductor (e.g., the Live wire) passes through the clamp maxilar. Clamping around multiple conductors carrying current in opposite directions will result in an incorrect reading, often zero.

Figura 6.1: Correct method for AC current measurement: Clamp around a single conductor (Live wire).

6.2 Incorrect AC Current Measurement

Niciodată clamp the multimeter around both the Live (L) and Neutral (N) wires simultaneously when measuring AC current. The magnetic fields will cancel each other out, leading to an inaccurate or zero reading.

Figura 6.2: Incorrect method for AC current measurement: Do not clamp around both Live (L) and Neutral (N) wires together.

7. Întreținere

7.1 Curățare

Ștergeți suprafața contoruluiasing cu anunțamp o lavetă și un detergent blând. Nu utilizați abrazive sau solvenți. Asigurați-vă că aparatul de măsură este complet uscat înainte de utilizare.

7.2 Înlocuirea bateriei

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1 to ensure continued accurate operation.

7.3 Depozitare

If the meter is not to be used for an extended period, remove the batteries to prevent leakage and damage to the device. Store the meter in a cool, dry place away from direct sunlight.

8. Depanare

Dacă multimetrul nu funcționează conform așteptărilor, luați în considerare următoarele probleme comune:

• Niciun afișaj sau afișaj slab: Verificați instalarea și încărcarea bateriilor. Înlocuiți bateriile dacă este necesar.
• Citiri incorecte: Ensure the correct function is selected on the rotary switch. Verify test lead connections. For current measurements, ensure only a single conductor is within the clamp maxilar.
• No response: Ensure the meter is turned ON. Check for any visible damage to the meter or test leads.

If problems persist, discontinue use and consult a qualified technician.
