3. Funtzionamendu-argibideak
3.1. Piztu/Itzali
To turn the multimeter on, rotate the function switch from the OFF position to any desired measurement function. To turn the multimeter off, rotate the function switch back to the OFF posizioa.
3.2. Function Selection (Rotary Dial)
The large rotary dial on the front of the multimeter allows you to select the desired measurement function. The EX330 features automatic ranging, which simplifies operation by automatically selecting the correct measurement range.
- VAC / VDC: Measures AC or DC Voltage.
- mA / 10A: Measures AC or DC Current (milliampere edo ampere).
- Ω: Measures Resistance.
- CAP: Measures Capacitance.
- Hz /%: Measures Frequency and Duty Cycle.
- ° F / ° C: Measures Temperature in Fahrenheit or Celsius.
- Diodoa / Jarraitasuna: Tests diodes and checks for circuit continuity.
3.3. Harremanik gabeko Voltage (NCV) Detekzioa
The NCV feature allows for quick detection of AC voltage without direct contact, enhancing safety when working with electrical systems. To use the NCV function, press and hold the NCV button. The top of the meter will illuminate and an audible tone will sound if AC voltage detektatzen da.

Bolumena neurtzekotage:
- Ezarri dial birakaria aukeran VAC or VDC dagokion moduan.
- Konektatu probako kable beltzara COM jack-a eta proba-kable gorria V/Ω/µA/CAP/Hz/Temp jack.
- Konektatu proba-zundak paraleloan neurtu beharreko zirkuituan edo osagaian.
- Irakurri liburukiatage balioa LCD pantailan.
3.5. Temperature Measurement (Type K)
The EX330 includes a Type K temperature probe for accurate temperature readings.
- Ezarri dial birakaria aukeran °F or °C.
- Plug the Type K temperature probe into the V/Ω/µA/CAP/Hz/Temp eta COM input jacks, observing polarity.
- Jarri tenperatura-sendaren punta neurtu beharreko tenperatura duen objektuaren gainean edo haren ondoan.
- Allow time for the reading to stabilize on the display.
3.6. Data Hold and Max Hold
- Sakatu EUTSI botoia pantailan uneko irakurketa izozteko. Sakatu berriro askatzeko.
- Sakatu MODUA button repeatedly while in certain functions to cycle through sub-functions or to activate GEHIEN EUTSI, which captures and displays the maximum measured value.
