Replace the Sensor Cap
To remove the Sensor Cap, first remove the Rubber Boot from the bottom of the probe. Grasp the plastic section of
the Probe body in one hand and turn the metal Sensor Cap counterclockwise to loosen it.
DO NOT USE A TOOL
to unscrew the Sensor Cap. If the Rubber O-ring is damaged, replace it with the O-ring included with the
Replacement Sensor Cap. Put the Replacement Sensor Cap onto the end of the probe and turn it clockwise until it
meets the metal part of the probe body.
DO NOT USE A TOOL
to install the new Sensor Cap.
NOTE
: The Sensor
Cap may be quite difficult to remove and replace. Make sure that your hands, the probe and the sensor cap are dry
and clean.
Replacement Sensor Cap Calibration
After a new Replacement Sensor Cap (PS-3604) is placed on the Optical Dissolved Oxygen probe, there are two
parts to the Sensor Cap Calibration process. First, enter the Sensor Calibration Coefficients into the software
(PASCO Capstone or SPARKvue). Second, do a one-point or two-point calibration as described previously.
