2. Segurtasun informazioa
Always adhere to safety precautions when using electrical testing equipment. Failure to do so may result in electric shock, injury, or damage to the meter or equipment under test.
- Ez gainditu neurketa-tarte bakoitzerako zehaztutako sarrera-balio maximoak.
- Oso kontuz ibili voltag30V AC RMS, 42V peak edo 60V DC-tik gorakoak. Bolumen hauektagshock arriskua dakar.
- Erabili aurretik, egiaztatu proba-kableak kaltetuta dauden. Ez erabili isolamendua hondatuta badago.
- Zirkuituari konektatu aurretik, ziurtatu funtzio-etengailua nahi den neurketarako posizio egokian dagoela.
- Ez erabili neurgailua hondatuta dagoela edo behar bezala funtzionatzen ez badu.
- Mantendu eskuak eta hatzak zundaren hesien atzean probak egiten ari zaren bitartean.
- Irakurketa zehatzak bermatzeko, aldatu bateriak berehala bateria baxuaren adierazlea agertzen denean.

4.1. irudia: Funtzio nagusiakview
The BT-38B is designed for ease of use with clearly labeled components:
- Lamp Argia: Provides illumination for working in dim environments.
- Test Lead Fixture: Securely holds the test leads.
- LCD pantaila: Neurketa-irakurketak, unitateak eta adierazleak erakusten ditu.
- Etengailua: Used to select between OFF, Voltage (V), and Ohms (Ω) / Continuity / Diode Test modes.
- EUTSI tekla: Press to hold the current reading on the display. Press again to exit.
- Atzeko argia/linterna botoia: Press for more than 2 seconds to turn on the backlight. Press again for more than 2 seconds to turn it off. The backlight automatically turns off after 15 seconds. A short press activates the front LED flashlight.
- SELECT tekla: In the Ohms/Continuity/Diode Test range, press this key to cycle through Resistance, Diode, and Continuity test modes. In Voltage mode, it switches between DC and AC voltage neurketak.
- Bateriaren estalkia: Access point for battery installation and replacement.
- COM Input Test Lead: Common (negative) input for measurements.

5. Konfigurazioa
5.1 Bateriaren instalazioa
The BTMETER BT-38B requires two AAA batteries for operation.

5.1. irudia: Bateriaren ordezkapena
- Locate the battery cover at the bottom of the multimeter.
- Rotate the battery bin counter-clockwise until it pops up.
- Carefully pull out the battery bin.
- Sartu bi AAA pila, polaritate zuzena ziurtatuz (+/-).
- Slide the battery bin back into the multimeter and rotate clockwise to secure it.
Bateriaren ikonoa denean 🔋 lights up on the screen, it indicates that the battery needs to be replaced.
6. Funtzionamendu-argibideak
6.1 Funtzionamendu Orokorra
- Turn the toggle switch from OFF to the desired measurement function (Voltage or Ohms/Continuity/Diode).
- Konektatu proba-kableak probatu beharreko zirkuituari edo osagaiari.
- Irakurri neurketa-balioa LCD pantailan.
- The meter features an Auto Power Off function after 15 minutes of inactivity to conserve battery life. A "BEEP" warning will sound before auto power off.
6.2 AC/DC Voltage Neurketa
The BT-38B can measure AC voltag2V-tik 600V-ra eta DC boltage from 200mV to 600V.
- Turn the toggle switch to the "V" position.
- Sakatu AUKERATU botoia AC eta DC bolumenaren artean aldatzekotage modes as needed. The display will indicate "AC" or "DC".
- Connect the red test lead to the positive (+) side of the circuit and the black test lead (COM) to the negative (-) side or ground.
- Irakurri liburukiatage balioa LCD pantailan.
6.3 Erresistentzia Neurketa
Measure resistance from 200 Ohm to 20M Ohm.
- Turn the toggle switch to the "Ω" position.
- Ziurtatu zirkuitua deskonektatuta dagoela erresistentzia neurtu aurretik.
- Connect the test leads across the component whose resistance you wish to measure.
- Irakurri erresistentziaren balioa LCD pantailan.
6.4 Jarraitasun proba
The built-in buzzer sounds if resistance is less than 50Ω.
- Turn the toggle switch to the "Ω" position.
- Sakatu AUKERATU button until the continuity symbol (a sound wave icon) appears on the display.
- Konektatu proba-kableak zirkuituan edo osagaian zehar.
- If there is continuity (low resistance), the buzzer will sound.
