Nastavitev

1. Namestitev baterije

The UNI-T UT151C requires a 9V (6F22) battery for operation. The battery is not included.

1. Prepričajte se, da je multimeter izklopljen, in odklopite vse merilne kable.
2. Poiščite predal za baterije na zadnji strani merilnika (glejte sliko 3).
3. Odvijte pritrdilni vijak(e) in odstranite pokrov baterije.
4. Connect a new 9V battery to the battery clips, observing correct polarity.
5. Vstavite baterijo v predal in namestite pokrov, ki ga pritrdite z vijakom(-i).

Opomba: Replace the battery immediately when the low battery indicator appears on the display to maintain measurement accuracy.

2. Priključitev merilnih vodnikov

Črno merilno vez vedno priključite na COM (skupni) priključek. Rdeči merilni kabel priključite na ustrezni vhodni priključek glede na vrsto meritve:

• Za voltage, resistance, capacitance, diode, continuity, and temperature measurements, connect the red lead to the VΩmA jack.
• Za meritve toka do 200 mA priključite rdeči kabel na VΩmA jack.
• Za meritve toka do 20 A priključite rdeči kabel na 20A jack.

Pozor: Incorrect lead connection can damage the meter or the circuit under test.

Navodila za uporabo

Follow these steps for various measurement functions.

3. Merjenje AC Voltage (V~)

1. Priključite črni vodnik na COM and the red lead to VΩmA.
2. Set the rotary switch to the desired V~ range (e.g., 2V, 20V, 200V, 750V).
3. Merilne kable priključite vzporedno na vir izmeničnega toka ali komponento.
4. Preberite AC voltage vrednost na LCD zaslonu.

4. Measuring DC Current (A-)

1. Pozor: Always connect the meter in series with the circuit. Never connect it in parallel across a voltage source when measuring current.
2. Odklopite napajanje tokokroga.
3. Prekinite tokokrog na mestu, kjer želite izmeriti tok.

Vzdrževanje

Pravilno vzdrževanje zagotavlja dolgo življenjsko dobo in natančnost vašega multimetra.

• Čiščenje: Obrišite ohišje z oglasomamp krpo in blag detergent. Ne uporabljajte abrazivov ali topil.
• Zamenjava baterije: Replace the 9V battery when the low battery indicator appears. Refer to the "Battery Installation" section for instructions.
• Zamenjava varovalke: If the current measurement function fails, the fuse may need replacement. This typically requires opening the back case. Refer to the safety warnings on the back of the meter (Figure 3) and consult a qualified technician if unsure. Use only fuses of the specified type and rating.
• Shranjevanje: Če merilnika ne uporabljate dlje časa, odstranite baterijo, da preprečite puščanje. Merilnik shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur.
