4. Nastavitev

4.1 Namestitev baterije

The meter requires batteries for operation. To install or replace batteries:

1. Ensure the meter is OFF and disconnect any test leads.
2. Poiščite pokrov predalčka za baterije na zadnji strani merilnika.
3. Odvijte pritrdilni vijak (vijake) in odstranite pokrov.
4. Vstavite nove baterije in pri tem upoštevajte pravilno polarnost (+ in -).
5. Namestite pokrov predalčka za baterije in ga pritrdite z vijakom(-i).

Note: The meter features auto power off to conserve battery life.

5. Navodila za uporabo

Before taking any measurements, ensure the meter is in good condition and the test leads are properly connected (if applicable).

5.1 Measuring AC Current (Clamp Funkcija)

This function allows non-contact measurement of AC current up to 400A.

1. Turn the function dial to the desired AC current range (2A, 20A, 200A, or 400A).
2. Pritisnite clamp trigger to open the clamp čeljust.
3. V ohišje vstavite en sam prevodnik (ne snop žic).amp čeljust. Prepričajte se, da je čeljust popolnoma zaprta.
4. Vrednost izmeničnega toka odčitajte na LCD-zaslonu.

Note: For accurate readings, ensure only one conductor is inside the clamp čeljust.

5.2 Merjenje AC/DC Voltage

The meter measures AC/DC voltage do 600V.

1. Insert the black test lead into the COM jack and the red test lead into the V·Ω jack.
2. Turn the function dial to the VDC or VAC position.
3. If measuring DC voltage, press the MODE button to select DC if necessary.

The meter includes a Type K thermometer for surface or air temperature measurements.

1. Ensure the meter is OFF and disconnect any test leads.
2. Insert the Type K thermocouple probe into the designated input jacks (usually marked with 'TEMP' or shared with V·Ω, check meter markings).
3. Turn the function dial to the temperature setting (often marked with °C or °F).
4. Place the thermocouple tip on or near the object whose temperature is to be measured.
5. Odčitajte temperaturo na LCD zaslonu.

5.7 Data Hold and Max Hold

• Gumb HOLD: Pritisnite gumb HOLD, da zamrznete trenutno odčitavanje na zaslonu. Ponovno pritisnite za sprostitev.
• Gumb MAX: Press the MAX button to capture and display the maximum measured value. Press again to exit MAX hold.
