Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equip-
ment and to keep the warranty valid.
Even original spare parts may be installed only by authorized
service personnel.
In case the equipment was opened by unauthorized person-
nel, no warranty regarding personal safety, measurement
accuracy, conformity with applicable safety measures or any
consequential damage is granted by the manufacturer.
Repair and Parts Replacement by Authorized Service Personnel
After opening the multimeter, live parts may be exposed.
Therefore, the multimeter must be disconnected from the mea-
suring circuit prior to opening its housing for repair, replace-
ment of parts or calibration. If repair or calibration cannot be
avoided unless the multimeter is open and live, this work must
be performed by a qualified person who understands the dan-
gers involved.
Faults and Extraordinary Stress:
If it has been ascertained that safe operation is no longer pos-
sible, take the multimeter out of service and secure it against
accidental use. Safe operation may not be possible
• if the multimeter shows obvious signs of damage,
• if the multimeter no longer functions correctly,
• after prolonged storage under adverse conditions,
• on account of severe stress during transport.
