Error Messages
The photometer will display an error message in the unlikely even 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 distributor.
Error messages are coded 7 and 9 and both 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
and use the light cap.
Error 9
indicates not enough light – follow 'Cleaning the Optics' routine.
Photometer Upgrade
It is now possible to upgrade the photometer with new test calibrations using a
computer system. This will ensure that users can always keep the instrument
up-to-date with the latest tests. Updates for the photometer can be supplied
on request via your local distributor. No special computer software is required.
Full instructions will be supplied with the upgrade data.
Guarantee
Palintest photometers are guaranteed for a period of two years from the
date of purchase, excluding accidental damage or damage caused by
unauthorised repair or misuse. The guarantee specifically excludes damage
caused by water or by ingress of chemical solutions. Should repair be
necessary, contact your local distributor quoting the serial number shown
on the back of the instrument.
This guarantee does not affect your
statutory rights.
Check Standards
Check standards are traceable solutions that can be used to validate the
performance of your photometer.
The materials used to manufacture the check standards are stable and
therefore the check standards give a known transmittance value (%T) at a
given wavelength.
Palintest recommends that check standards are purchased with your
photometer to enable periodical checks to be carried out on your instrument.
