3.2 USE OF SPECIAL OPTIONS:
Auto Rinse Water Flow Control
(via Resistivity Probe and Controller
in Conjunction with a Solenoid Valve)
,
continued
How to use this feature:
if you ordered the
resistivity monitor feature, the user-settable
controller and probe are already installed on your
machine. Before processing, you should set the
controller to the lowest level of resistivity that is
considered acceptable for the final rinse tank.
Refer to manufacturer’s instructions in the
“Reference” section of this manual for further
information about the use of your resistivity
monitor.
Hints for successful use of this feature:
The
resistivity probe must be in flowing water (achieved
by placing it in the overflow weir).
Space between the probe points should be kept
free and open, since excessive air bubbles or build-
up of dirt or grit between the probe points will
cause faulty readings.
CAUTION: Do not allow the probe points to run
“dry.” They will eventually burn out in this
condition.
Controller may be calibrated according to instructions in
the manufacturer’s literature in the “Reference” section of
this manual.
