SERVICE REQUIREMENT
The photometer is fitted with long-life light sources and contains no user-
serviceable components beyond cleaning. If the instrument requires servicing
or repair, this can be arranged through our Technical Support Department (+1
937 767-7241, (800) 897-4151,
[email protected] or visit www.ysi.com to
find an authorized service center).
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 our Technical Support Department for advice.
Error messages are coded 1 – 10. Errors 1, 2, 3, 4, 5 and 6 are internal self-
checks. In the first instance, the user should change the instrument batteries. If
the error message still appears, it indicates a potential electronic issue with the
instrument.
Errors 7, 8, 9 and 10 relate to blanking in the instrument. In the first instance,
the user should check operating technique and sample clarity. If these are in
order then these errors indicate a potential issue in the instrument optics.
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
disk or via the YSI web site (
www.YSI.com ). No special computer software is
required. Full instructions will be supplied with the upgrade data.
COMPUTER CONTROLLED OPERATION
The photometer can be controlled from a computer using suitable control
software. Such software is available from software houses or from water
treatment specialists to cover specific applications. These software programs
typically instruct the photometer to go through a predetermined series of tests
specific to that application, and then automatically receive data from the
photometer and process the test results. The internal software of the
photometer is able to receive computer commands to start new sample,
receive test program number, receive sample number and instigate
continuation test. Programmers requiring further details should contact YSI
Technical Support.
