2.1. Installazzjoni tal-batterija
The EX330 multimeter requires two AAA batteries for operation. To install or replace batteries:
- Kun żgur li l-multimetru huwa mitfi.
- Sib il-kompartiment tal-batterija fuq wara tal-unità.
- Uża tornavit biex tiftaħ l-għatu tal-kompartiment tal-batterija.
- Daħħal żewġ batteriji AAA, waqt li tosserva l-polarità korretta (+ u -) kif indikat ġewwa l-kompartiment.
- Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha bil-kamin.
2.2. Konnessjoni tal-wajers tat-test
The multimeter comes with a set of red and black test leads. Proper connection is crucial for accurate and safe measurements.
- Dejjem qabbad il-wajer tat-test iswed mal- COM Jack tad-dħul (komuni).
- Għal ħafna mill-volumtage, resistance, and continuity measurements, connect the red test lead to the V/Ω/µA/CAP/Hz/Temp jack tad-dħul.
- Għal kejl tal-kurrent sa 400mA, qabbad il-wajer tat-test aħmar mal- mA jack tad-dħul.
- For high current measurements up to 10A, connect the red test lead to the 10A jack tad-dħul.
3. Istruzzjonijiet Operattivi
3.1. Power On/Off
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 pożizzjoni.
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 jew ampere).
- Ω: Measures Resistance.
- KAP: Measures Capacitance.
- Hz /%: Measures Frequency and Duty Cycle.
- ° F / ° C: Measures Temperature in Fahrenheit or Celsius.
- Diode / Kontinwità: Tests diodes and checks for circuit continuity.
3.3. Mhux ta' Kuntatt Voltage (NCV) Sejbien
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 jiġi skopert.
3.4. TitjiratagKejl elettroniku (AC/DC)
Biex tkejjel il-voltage:
- Issettja l-arloġġ li jdur fuq VAC or VDC kif xieraq.
- Qabbad iċ - ċomb iswed tat - test mal - COM jack u l-wajer tat-test aħmar għall- V/Ω/µA/CAP/Hz/Temp jack.
- Qabbad il-probi tat-test b'mod parallel madwar iċ-ċirkwit jew il-komponent li għandu jitkejjel.
- Aqra l-voltage valur fuq il-wiri LCD.
3.5. Temperature Measurement (Type K)
The EX330 includes a Type K temperature probe for accurate temperature readings.
- Issettja l-arloġġ li jdur fuq °F or °C.
- Plug the Type K temperature probe into the V/Ω/µA/CAP/Hz/Temp u COM jacks tad-dħul, waqt li tosserva l-polarità.
- Poġġi l-ponta tas-sonda tat-temperatura fuq jew viċin l-oġġett li trid titkejjel it-temperatura tiegħu.
- Allow time for the reading to stabilize on the display.
3.6. Data Hold and Max Hold
- Agħfas il- ŻOMM buttuna biex tiffriża l-qari attwali fuq id-displej. Agħfas mill-ġdid biex tirrilaxxa.
- Agħfas il- MODALITÀ button repeatedly while in certain functions to cycle through sub-functions or to activate ŻOMM MAX, which captures and displays the maximum measured value.
