4. Gosod

4.1 Gosod Batri

1. Ensure the meter is powered off.
2. Lleolwch glawr adran y batri ar gefn y mesurydd.
3. Use a suitable screwdriver to open the cover.
4. Insert the battery, observing the correct polarity (+/-).
5. Amnewid gorchudd adran y batri a'i ddiogelu gyda'r sgriw.

4.2 Pweru Ymlaen/Diffodd

• I droi’r mesurydd ymlaen, pwyswch y GRYM botwm.
• I ddiffodd y mesurydd, pwyswch a daliwch y GRYM button until the display turns off. The meter also features an auto power off function to conserve battery life.

5. Cyfarwyddiadau Gweithredu

5.1 Measuring AC Leakage Current

1. Pwer ar y mesurydd.
2. Agorwch y clamp gên trwy wasgu'r sbardun.
3. Carefully place the conductor (e.g., power cable) within the clamp jaw. Ensure the jaw is fully closed around the conductor. For accurate leakage current measurement, clamp around both the live and neutral conductors of a single-phase circuit, or all phase conductors of a multi-phase circuit.
4. Read the leakage current value displayed on the LCD screen.

5.2 Swyddogaeth Dal Data

I rewi'r darlleniad cyfredol ar yr arddangosfa, pwyswch y DALWCH botwm. Pwyswch ef eto i ryddhau'r daliad ac ailddechrau darlleniadau byw.

5.3 Peak Hold Function

The Peak Hold function captures and displays the maximum peak value of the measured current. Refer to the specific button on your device for activating this feature.

5.4 Storio Data

The meter can store up to 99 sets of measurement data. Consult the detailed manual for specific instructions on how to save and recall data sets using the device's interface.

5.5 RS-232 Data Transmission

The RS-232 interface allows for data transfer to a computer for further analysis or logging. Connect the meter to a computer using the provided RS-232 cable and use compatible software (not included) for data communication.

6. cynnal

6.1 Glanhau

Sychwch c y mesuryddasing gyda hysbysebamp lliain a glanedydd ysgafn. Peidiwch â defnyddio sgraffinyddion na thoddyddion. Gwnewch yn siŵr bod y mesurydd yn sych cyn ei storio neu ei ddefnyddio.

6.2 Batri Newydd

When the low battery indicator appears on the display, replace the battery promptly to ensure accurate measurements. Refer to section 4.1 for battery installation instructions.

6.3 Storio

When not in use for extended periods, remove the battery and store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Datrys Problemau

• No Display/Meter Not Powering On: Gwiriwch osodiad y batri a gwnewch yn siŵr bod digon o wefr ar y batri. Amnewidiwch os oes angen.
• "OL" Indication (Overload): The measured current exceeds the meter's maximum range. Remove the clamp from the conductor immediately to prevent damage.
• Darlleniadau Anghywir: Sicrhewch y clamp jaw is fully closed around a single conductor or a bundle of conductors for leakage measurement. Avoid external magnetic fields.
• Arwydd Batri Isel: Replace the battery as soon as possible to maintain measurement accuracy.
