2. Sigurnosne informacije
Always observe the following safety precautions to prevent electric shock or personal injury, and to avoid damage to the meter or the equipment under test.
- Read and understand all instructions in this manual before using the meter.
- Ne koristite mjerač ako izgleda oštećeno ili ako je izolacija oštećena.
- Ensure the rotary switch is in the correct position for the measurement being performed.
- Ne prekoračujte maksimalna ograničenja unosa za bilo koju funkciju.
- Budite oprezni kada radite sa voltagiznad 30V AC RMS, 42V peak ili 60V DC. Ovi volumenitagpredstavljaju opasnost od strujnog udara.
- Odmah zamijenite bateriju kada se pojavi indikator slabe baterije kako biste osigurali tačna očitavanja.
- Ne koristite mjerač u okruženjima eksplozivnog plina, pare ili prašine.

4. Podešavanje i ugradnja baterija
4.1 Instalacija baterije
- Provjerite je li mjerač ISKLJUČEN.
- Pronađite poklopac odjeljka za baterije na stražnjoj strani mjerača.
- Koristite odvijač da biste odvrnuli vijak koji pričvršćuje poklopac baterije.
- Insert one 9V 6F22 battery, observing the correct polarity (+/-).
- Vratite poklopac baterije i pričvrstite ga vijkom.
4.2 Početno uključivanje
Turn the rotary switch from the "OFF" position to any measurement function. The LCD display will illuminate, indicating the meter is ready for use. If the display does not light up, check the battery installation or replace the battery.
5. Uputstvo za upotrebu
The KAISE SK-7720 offers various measurement modes. Always select the appropriate function before connecting the meter to a circuit.
5.1 Current Measurement (A)
Za mjerenje naizmjenične ili istosmjerne struje:
- Okrenite okretni prekidač u položaj A+V (DC Current) or A+Hz (AC Current) position.
- Otvorite clamp čeljust pritiskom na polugu.
- Zatvorite samo jedan provodnik strujnog kola unutar clamp jaw. Ensure the jaw is fully closed. The maximum measurement conductor diameter is 36 mm (1.4 inches).
- Očitajte trenutnu vrijednost na LCD zaslonu.
5.2 svtage mjerenje (V)
Za mjerenje AC ili DC voltage:
- Spojite crni ispitni vod na COM terminal i crveni ispitni kabl do VΩ terminal.
- Okrenite okretni prekidač u položaj A+V (DC Voltage) ili V+Hz (AC Voltage) položaj.
- Spojite mjerne kabele paralelno s krugom ili komponentom koju želite izmjeriti.
- Pročitajte voltage vrijednost na LCD zaslonu.
5.3 Mjerenje otpora (Ω)
Za mjerenje otpora:
- Spojite crni ispitni vod na COM terminal i crveni ispitni kabl do CH2 (°C Ω) terminal.
- Okrenite okretni prekidač u položaj Ω pozicija.
- Ensure the circuit or component under test is de-energized before connecting the test leads.
- Spojite mjerne kablove preko komponente.
- Očitajte vrijednost otpora na LCD ekranu.
5.4 Mjerenje frekvencije (Hz)
Frequency can be measured in conjunction with AC Current or AC Voltage:
- For AC Current frequency, select A+Hz.
- Za AC Voltage frequency, select V+Hz.
- The frequency value will be displayed on the secondary display or indicated by a specific symbol.
5.5 Temperature Measurement (°C)
Za mjerenje temperature:
- Connect a compatible temperature probe (not included) to the CH2 (°C Ω) i COM terminali.
- Okrenite okretni prekidač u položaj °C pozicija.
