• Multiple test voltages: 250V, 500V in 1000V.
• Measurement range up to 2000 MΩ.
• Clear LCD display with 1999 counts.

2. Varnostne informacije

Always adhere to the following safety precautions to prevent personal injury and damage to the instrument:

• Preberite celoten priročnik before using the instrument.
• Do not use the tester if it appears damaged or is operating abnormally.
• Ensure the circuit under test is de-energized and locked out before connecting the test leads.
• Nosite ustrezno osebno zaščitno opremo (OZO), including insulated gloves and safety glasses.
• Avoid touching the test leads or the circuit under test during measurement, especially when high test voltagse uporabljajo.
• Discharge the circuit completely after testing before disconnecting the leads.
• Do not operate the tester in wet environments or in the presence of explosive gases or dust.
• Zamenjajte baterije promptly when the low battery indicator appears.

3. Vsebina paketa

Po odprtju paketa preverite, ali so vsi predmeti prisotni in nepoškodovani:

• Kaise EM480A Insulation Tester

4. Nastavitev

4.1 Namestitev baterije

The Kaise EM480A requires 6 AA batteries for operation. If the batteries are not pre-installed, follow these steps:

1. Poiščite predal za baterije na zadnji strani testerja.
2. Z izvijačem odprite pokrov predalčka za baterije.
3. Vstavite 6 baterije AA in pazite na pravilno polarnost (+ in -), kot je označeno v predalu.
4. Ponovno namestite pokrov prostora za baterije in ga pritrdite z vijakom.

4.2 Priključitev merilnih vodnikov

Connect the red and black test leads to the corresponding input terminals on the tester. Ensure a secure connection to prevent inaccurate readings or hazards.

5. Navodila za uporabo

5.1 Vklop/izklop

To power on the tester, rotate the function selector dial to any desired measurement function. To power off, rotate the dial to the 'OFF' position.

5.2 Izvedba preizkusa izolacijske upornosti

Follow these steps to perform an insulation resistance measurement:

1. Zagotovite varnost: Verify that the circuit under test is completely de-energized and isolated from all power sources. Apply lockout/tagven postopke.
2. Povežite potencialne stranke: Connect the test leads to the circuit or component you wish to test. Typically, one lead connects to the conductor and the other to ground or another conductor.
3. Izberite testno glasnosttage: Rotate the function selector dial to the desired insulation test voltage (250V, 500V, or 1000V). Choose a voltage appropriate for the insulation rating of the circuit.
4. Začni test: Press and hold the 'TEST' button. The tester will apply the selected voltage and display the insulation resistance value on the LCD.
5. Preberite meritev: Observe the reading on the LCD. The unit will typically be in MΩ (Megaohms).
6. Discharge Circuit: Release the 'TEST' button. The tester will automatically discharge any residual charge in the circuit. Wait for the discharge to complete before disconnecting the leads.
7. Disconnect Leads: Once the circuit is safely discharged, disconnect the test leads.

Opomba: Always refer to relevant electrical codes and standards for acceptable insulation resistance values for specific applications.

6. Vzdrževanje

6.1 Čiščenje

Wipe the instrument's casing z oglasomamp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure the tester is completely dry before storage or next use.

6.2 Zamenjava baterije

When the low battery indicator appears on the display, replace all 6 AA batteries promptly to ensure accurate measurements. Refer to Section 4.1 for battery installation instructions. Dispose of old batteries responsibly according to local regulations.

6.3 Shranjevanje

Tester shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur. Če ga shranjujete dlje časa, odstranite baterije, da preprečite puščanje.
