Problem
Causes and Solutions
Note
Stir Mode Select defaults to "Auto" each
time the power of the bath is cycled off
and back on. Therefore, this parameter
has to be set each time the bath is
powered on if "Str-ON" is the desired
mode of operation.
If stir motor still does not function, contact
an Authorized Service Center for
assistance.
Note
Before performing the memory check, you
need to record the controller calibration
parameters (found in the CAL menu of the
instrument) and any user-adjusted
parameters that you have changed (such
as the programmable set points and
proportional band).
Memory Check
Doing a memory check is the easiest way
to verify the ability of the battery to
maintain controller parameters.
1.
Power off the instrument.
2.
Disconnect the instrument from AC
power for 10 seconds.
3.
Reconnect the AC power and power
on the instrument.
4.
If the display shows "InIT" and/or the
cycle count shows a low number
such as 0002, the battery is spent
and should be replaced. Contact an
Authorized Service Center for
assistance.
5.
After replacing the battery, you must
reprogram the calibration and user-
adjustable parameters into the
controller.
