Error Messages

The photometer will display an error message in the

unlikely event of malfunction. These error messages are
mainly designed to assist service staff in diagnosing

instrument faults. In the event of an error message
appearing on the photometer display, contact your local
Palintest Technical Services Department or your local

distributor.

Error messages are coded 7, 8 and 9 and all relate to

blanking the instrument. In the first instance, the user
should check the operating technique and sample

clarity. If these are in order, then these errors indicate
a fault in the optics :-

Error 7 indicates too much light – remove the instrument

from bright light.

Error 8 indicates a fault with one of the optics components,

and requires service assistance.

Error 9 indicates not enough light – follow ‘Cleaning
the Optics’ routine.
If the problem persists, contact your local Palintest
Branch or distributor.
