6. Funtzionamendu-argibideak
6.1 Piztu/Itzaltzea
To power on the meter, rotate the rotary switch from the 'OFF' position to any desired measurement range (e.g., 60A, 20mA, 2mA). To power off, rotate the switch back to the 'OFF' position.
6.2 AC Leakage Current Measurement
- Select the appropriate AC current range (60A, 20mA, or 2mA) using the rotary switch. Start with the highest range if the current value is unknown.
- Ireki clamp masailezurra abiarazlea sakatuz.
- Enclose the single conductor (not multiple conductors) through which the leakage current is to be measured within the clamp masailezurra. Ziurtatu masailezurra guztiz itxita dagoela.
- Read the current value displayed on the LCD. If the reading is too low for the selected range, switch to a lower range for better resolution.
6.3 Datuak gordetzeko funtzioa
Press the 'HOLD' button to freeze the current reading on the display. Press the 'HOLD' button again to release the reading and resume live measurement.
6.4 Itzalketa automatikoa
The meter is equipped with an Auto Power Off feature to conserve battery life. If no operation is performed for approximately 15 minutes, the meter will automatically power off. To reactivate the meter, rotate the rotary switch to 'OFF' and then back to a measurement range, or press any button.
7. Mantentzea
7.1 Garbiketa
Garbitu neurgailuaren kaxa iragarkiarekinamp oihal eta detergente leun batekin. Ez erabili urratzailerik edo disolbatzailerik. Ziurtatu neurgailua guztiz lehor dagoela erabili aurretik.
7.2 Bateria ordezkatzea
When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Always use two new LR44 1.5V batteries.
7.3 Biltegiratzea
Neurgailua denbora luzez erabiliko ez bada, kendu bateriak isuriak saihesteko eta gorde neurgailua leku fresko eta lehor batean, eguzki-argitik babestuta.
8. Arazoak
- Ez dago pantailarik: Egiaztatu bateriaren instalazioa eta ziurtatu bateriak ez daudela agortuta. Ordeztu behar izanez gero.
- Irakurketa okerrak: Ziurtatu clamp jaw is fully closed around a single conductor. Verify the correct measurement range is selected.
- Meter Does Not Power On: Confirm batteries are correctly installed and charged. Rotate the function switch to an 'ON' position.
