13.1.

Trouble shooting

In case of troubles, the user can check several points himself, before contacting the 
international service department. We are stating some common troubles, that can 
be solved easily.

Trouble

Causes and remedies

The equipment cannot be powered up:

Check fuse, cables, connectors

Temperature indicator indicates - - - :

The error message E 1 interrupts a meas-
urement. Input connector at the rear 
panel or Pt 100 sensor or extension cable 
is defect. Replace Pt 100 temperature 
assembly. Make sure the connector is 
fitting into the socket correctly.
