2. Gwybodaeth Diogelwch

Dilynwch ragofalon diogelwch bob amser wrth ddefnyddio offer profi trydanol. Gall methu â gwneud hynny arwain at sioc drydanol, anaf, neu ddifrod i'r mesurydd neu'r offer sy'n cael ei brofi.

• Peidiwch â rhagori ar y gwerthoedd mewnbwn uchaf a bennir ar gyfer pob ystod fesur.
• Byddwch yn ofalus iawn wrth weithio gyda chyftaguwchlaw 30V AC RMS, 42V brig, neu 60V DC. Mae'r cyfrolau hyntages yn peri perygl sioc.
• Archwiliwch geblau prawf am ddifrod cyn pob defnydd. Peidiwch â defnyddio os yw'r inswleiddio wedi'i beryglu.
• Ensure the function switch is in the correct position for the desired measurement before connecting to the circuit.
• Do not operate the meter if it appears damaged or is not functioning properly.
• Keep hands and fingers behind the probe barriers during testing.
• Amnewidiwch y batris ar unwaith pan fydd y dangosydd batri isel yn ymddangos i sicrhau darlleniadau cywir.

4. Cynnyrch Drosview a Swyddogaethau Allweddol

Figure 4.1: Key Functions Overview

The BT-38B is designed for ease of use with clearly labeled components:

• Lamp Golau: Provides illumination for working in dim environments.
• Test Lead Fixture: Securely holds the test leads.
• Arddangosfa LCD: Yn dangos darlleniadau mesur, unedau a dangosyddion.
• Toglo Switch: Used to select between OFF, Voltage (V), and Ohms (Ω) / Continuity / Diode Test modes.
• Allwedd HOLL: Press to hold the current reading on the display. Press again to exit.
• Botwm Goleuadau Cefn/Fflashgolau: 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.
• Allwedd DEWIS: 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 mesuriadau.
• Gorchudd Batri: Access point for battery installation and replacement.
• COM Input Test Lead: Common (negative) input for measurements.

5. Gosod

5.1 Gosod Batri

The BTMETER BT-38B requires two AAA batteries for operation.

Ffigur 5.1: Amnewid Batri

1. Locate the battery cover at the bottom of the multimeter.
2. Rotate the battery bin counter-clockwise until it pops up.
3. Carefully pull out the battery bin.
4. Mewnosodwch ddau fatri AAA, gan sicrhau'r polaredd cywir (+/-).
5. Slide the battery bin back into the multimeter and rotate clockwise to secure it.

Pan fydd yr eicon batri 🔋 lights up on the screen, it indicates that the battery needs to be replaced.

6. Cyfarwyddiadau Gweithredu

6.1 Gweithrediad Cyffredinol

• Turn the toggle switch from OFF to the desired measurement function (Voltage or Ohms/Continuity/Diode).
• Cysylltwch y gwifrau prawf â'r gylched neu'r gydran sy'n cael ei phrofi.
• Darllenwch y gwerth mesur ar yr arddangosfa LCD.
• 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 Cyftage Mesur

The BT-38B can measure AC voltage o 2V i 600V a chyfaint DCtage from 200mV to 600V.

1. Turn the toggle switch to the "V" position.
2. Gwasgwch y DETHOL button to switch between AC and DC voltage modes as needed. The display will indicate "AC" or "DC".
3. Connect the red test lead to the positive (+) side of the circuit and the black test lead (COM) to the negative (-) side or ground.
4. Darllenwch y cyftage gwerth ar yr arddangosfa LCD.

6.3 Mesur Gwrthiant

Measure resistance from 200 Ohm to 20M Ohm.

1. Turn the toggle switch to the "Ω" position.
2. Gwnewch yn siŵr bod y gylched wedi'i dad-egnïo cyn mesur gwrthiant.
3. Cysylltwch y gwifrau prawf ar draws y gydran yr hoffech fesur ei gwrthiant.
4. Darllenwch y gwerth gwrthiant ar yr arddangosfa LCD.

6.4 Prawf Parhad

The built-in buzzer sounds if resistance is less than 50Ω.

1. Turn the toggle switch to the "Ω" position.
2. Gwasgwch y DETHOL button until the continuity symbol (a sound wave icon) appears on the display.
3. Cysylltwch y gwifrau prawf ar draws y gylched neu'r gydran.
4. If there is continuity (low resistance), the buzzer will sound.

6.5 Swyddogaeth Dal Data

I rewi'r darlleniad cyfredol ar yr arddangosfa:

• Gwasgwch y DALWCH button during a measurement. The "HOLD" indicator will appear.
• Gwasgwch y DALWCH button again to release the data hold and resume live readings.

6.6 Goleuadau Cefn a Fflacholau

Ffigur 6.1: Fflachlamp LED mewn Defnydd

• Golau cefn: Press and hold the backlight button (sun icon) for more than 2 seconds to turn on the LCD backlight. Press and hold again for more than 2 seconds to turn it off. The backlight will automatically turn off after 15 seconds.
• Flashlight: A short press of the backlight button (sun icon) will activate the front LED flashlight, useful for illuminating dark work areas.

7. cynnal

7.1 Glanhau

Wipe the meter with a dry, clean cloth. Do not use abrasives or solvents.

7.2 Batri Newydd

Cyfeiriwch at Adran 5.1 am gyfarwyddiadau manwl ar ailosod batri. Defnyddiwch fatris AAA ffres bob amser.

7.3 Storio
