5. Gosod
5.1. Gosod Batri
- Sicrhewch fod y ddyfais wedi'i phweru i ffwrdd.
- Locate the battery compartment cover on the rear of the unit.
- Use a screwdriver (if necessary) to open the cover.
- Insert two (2) AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Amnewid y clawr adran batri a'i ddiogelu.
5.2. Troi ymlaen yn gychwynnol
After battery installation, turn the function dial from "OFF" to any measurement setting to power on the device. The display should illuminate, indicating readiness for use.
6. Cyfarwyddiadau Gweithredu
6.1. Pŵer Ymlaen / I ffwrdd
- To power on, rotate the function dial from the "OFF" position to the desired measurement function.
- To power off, rotate the function dial back to the "OFF" position.
6.2. AC Current Measurement (Clamp)
- Rotate the function dial to the "A" (Current) setting.
- Agorwch y clamp jaw by pressing the lever.
- Enclose only one conductor (live or neutral) within the clamp gên. Gwnewch yn siŵr bod yr ên wedi'i chau'n llwyr.
- Darllenwch y gwerth cyfredol ar yr arddangosfa LCD.
6.3. Cyftage Mesur (V)
- Rotate the function dial to the "V" (Voltage) gosodiad.
- Connect the red test lead to the "V" input terminal and the black test lead to the "COM" input terminal.
- Cysylltwch y gwifrau prawf yn gyfochrog ar draws y gylched neu'r gydran i'w mesur.
- Darllenwch y cyftage gwerth ar yr arddangosfa LCD.
6.4. Power Measurement (W, Wh, var, VA)
The CM3286 can measure various power parameters. Select the appropriate setting on the function dial (W for active power, Wh for energy, var for reactive power, VA for apparent power). Connect test leads for voltage ac clamp the jaw around the current conductor as per the specific measurement method outlined in the full manual (not provided here, but implied by the device's capabilities).
