5. Nastavitev

5.1. Namestitev baterije

1. Prepričajte se, da je multimeter izklopljen.
2. Poiščite pokrov predala za baterije na zadnji strani enote.
3. Z izvijačem odvijte vijak(e), s katerim je pritrjen pokrov.
4. Remove the cover and insert four (4) AAA batteries, observing correct polarity (+/-).
5. Namestite pokrov in ga pritrdite z vijakom(-i).

5.2. Priključitev merilnih vodnikov

Insert the test leads into the appropriate input terminals:

• Črno merilno vez vedno priključite na COM terminal.
• Za voltage, resistance, continuity, diode, capacitance, and frequency measurements, connect the red test lead to the V Ω •))) →|← •F Hz terminal.
• For current measurements (up to 10A), connect the red test lead to the A terminal.

6. Navodila za uporabo

Before making any measurement, ensure the test leads are correctly connected and the rotary switch is set to the appropriate function.

6.1. Merjenje AC/DC volumnatage (V~ / V-)

1. Vrtljivo stikalo nastavite na V~ za AC voltage oz V- za DC voltage.
2. Merilne kable priključite vzporedno na vezje ali komponento, ki jo želite izmeriti.
3. Preberite zvtage vrednost na zaslonu.

6.2. Measuring AC/DC Current (A~ / A-)

WARNING: Never connect the multimeter in parallel across a voltage source when in current measurement mode. This can cause a short circuit and damage the meter or circuit.

1. Turn OFF power to the circuit.
2. Vrtljivo stikalo nastavite na A~ for AC current or A- for DC current.
3. Connect the multimeter in series with the circuit, breaking the circuit to insert the meter.
4. Napajajte vezje.
5. Odčitajte trenutno vrednost na zaslonu.

6.3. Merjenje upornosti (Ω)

1. Prepričajte se, da je tokokrog ali komponenta brez napetosti.
2. Vrtljivo stikalo nastavite na Ω.
3. Priključite merilne kable na komponento.
4. Na zaslonu preberite vrednost upora.

6.4. Continuity Test (•))) )

1. Prepričajte se, da je tokokrog ali komponenta brez napetosti.
2. Vrtljivo stikalo nastavite na •))).
3. Connect the test leads across the component or wire.
4. Zvočni pisk označuje prevodnost (nizek upor). Na zaslonu se bo prikazala vrednost upora.

6.5. Diode Test (→|←)

1. Ensure the diode is de-energized and isolated from the circuit.
2. Vrtljivo stikalo nastavite na →|←.
3. Rdeči kabel priključite na anodo, črni pa na katodo. Premični toktage drop (e.g., 0.5V to 0.8V) should be displayed.
4. Reverse the leads. The display should show OL (Open Loop) for a good diode.

6.6. Merjenje kapacitivnosti (F)

7. Vzdrževanje

7.1. Čiščenje

Obrišite ohišje z oglasomamp krpo in blagim detergentom. Ne uporabljajte abrazivnih sredstev ali topil. Pred uporabo se prepričajte, da je merilnik popolnoma suh.

7.2. Zamenjava baterije

When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Use only new AAA batteries of the same type.

7.3. Zamenjava varovalke

If the current measurement function fails, the fuse may need replacement. The DT4252 uses a 10A fused input. Refer to the detailed service manual for fuse replacement procedures, or contact qualified service personnel.

8. Odpravljanje težav

If the multimeter does not operate correctly, check the following common issues:

• Brez zaslona: Preverite namestitev baterij in njihovo napolnjenost. Po potrebi zamenjajte baterije.
• Nepravilni odčitki: Ensure the function switch is set correctly for the measurement type. Verify test lead connections. Check for damaged test leads.
• Prikaz "OL" (preobremenitev): The measured value exceeds the selected range. Switch to a higher range or ensure the input is within the meter's specifications.
• Trenutna meritev ne deluje: Check the 10A fuse. If blown, it needs replacement by qualified personnel.

For persistent issues, contact Hioki customer support.
