EC / TDS PROBE MAINTENANCE
Probe can be compensated for normal contamination by a
process of recalibration. When calibration can no longer
be achieved, remove the conductivity probe from the sys-
tem for maintenance.
PERIODIC MAINTENANCE
Inspect the probe and the cable. The cable used for the
connection to the controller must be intact and there must
be no points of broken insulation on the cable.
Connectors must be perfectly clean and dry.
CLEANING PROCEDURE
Rinse the probe with tap water. If a more thorough cleaning
is desired, remove the sleeve and clean the platinum sen-
sors with a nonabrasive cloth or HI7061 cleaning solution.
Reinsert the sleeve in the same direction as before.
Recalibrate the instrument before reinserting the probe in
the system.
Note Always recalibrate the instrument when attaching a new
probe.
