4.3 Prova de cable en fase

To identify live and neutral lines in an AC circuit:

1. Select the Live Wire Test function (refer to your device's specific function selection).
2. Insert the red test probe into the socket or touch the conductor.
3. A large value displayed indicates a live line, while a small value indicates a neutral line.

4.4 Funció de retenció de dades

Premeu el botó HOLD/Y button to freeze the current reading on the display. Press it again to release the hold.

4.5 Maximum Hold Function

Premeu el botó MAXH button to capture and display the maximum measured value. Press it again to exit this mode.

5. Manteniment

Un manteniment adequat garanteix la longevitat i la precisió del vostre multímetre.

5.1 Neteja

Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from any circuits before cleaning.

5.2 Substitució de la bateria
