MAINTENANCE
To keep the instrument clean, wipe the case with a damp cloth and detergent, do not use abrasives or solvents.
Any adjustment, maintenance and repair of opened instrument with voltage applied should be avoided as far as
possible and, if inevitable, shall be carried out by a skilled person who is aware of the hazard involved.
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be se-
cured against any unintended operation.
The protection is likely to be impaired if, for example, the apparatus:
— shows visible damage,
— fails to perform the intended measurements,
— has been subjected to prolonged storage under unfavourable conditions,
— has been subjected to severe transport stresses.
: CAUTION (refer to User Instructions).
