Maintenance; Cleaning - Wiha 45221 Manual De Instrucciones

INSTRUCTION MANUAL
If a phase is missing, the warning LED lights up to indicate that no clear phase se-
quence (direction of rotation) can be recognized.
If the neutral conductor N or the protective conductor PE is connected to a measuring
input instead of L1, L2 or L3, the warning LEDs will also light up. Thus, a faulty con-
nection is also indicated in this case.

Maintenance

When using the instrument in compliance with the instruction manual, no special
maintenance is required.

Cleaning

If the instrument is dirty after daily usage, it is advised to clean it by using a humid cloth
and a mild household detergent. Prior to cleaning, ensure that instrument is discon-
nected from external voltage supply and any other instruments connected. Never use
acid detergents or resolvent for cleaning. After cleaning, do not use the phase rotation
indicator for a period of approx. 2 h.
