Temperature Controller Error Messages

The temperature controller performs self-diagnostics when the degasser is turned on and while
operating. If an error occurs during self-diagnostics, one of the following error messages will
be displayed.

uuuu

LLLL

Cause:

Temperature has risen substantially above temperature scale range or
the temperature sensor has burned out (open circuit).

Action:

Observe the display. The temperature will be displayed if it is
decreasing. If the temperature does not decrease, the message will
remain displayed. Turn off power to the instrument and call the
appropriate service personnel.

Cause:

Temperature has fallen substantially below temperature scale range or
the temperature sensor has failed (short circuit).

Action:

Observe the display. The temperature will be displayed if it is increas-
ing. If the temperature does not increase, the message will remain
displayed. Turn off power to the instrument and call the appropriate
service personnel.
