7.1 Periodic calibration
It is essential that all measuring instruments are regularly calibrated in order for the
technical specification listed in this manual to be guaranteed. We recommend an annual
calibration. The calibration should be done by an authorized technical person only.

There are two fuses available from front panel:
F1 = F2 = T 16 A / 250 V (32 × 6,3 mm): intended for instrument protection.
If the instrument does not respond after connection to mains supply, disconnect the
mains supply and accessories and then check these fuses. For position of fuses refer to
chapter 2.1 Front panel.

before replacing the fuses or opening the instrument. Disconnect all test leads
and the instrument mains cord before removing fuse cover!
