3.3 Cleaning the Moisture Probe
To clean your HygroPro
II
moisture probe (i.e., Hygro
II
RTE), carefully follow the instructions in this section.
3.3.1 Preparing to Clean the Probe
To clean the moisture probe, the following items are required:
•
Two glass ( NOT metal) containers with approximately 300 ml of reagent-grade Hexane or Toluene in each
container.
• One glass ( NOT metal) container with approximately 300 ml of distilled (NOT deionized) water.
IMPORTANT: Make sure the containers are deep enough to completely submerge the moisture probe after it is
disconnected from the display head. Do not place the transmitter module into any of these solvents.
Insert only the moisture sensor mounted on the probe into the solvents.
• Rubber or latex gloves
• An oven set at 50°C ± 2°C (122°F ± 3.6°F)
• 1-1/8” wrench
3.3.2 Replacing the RTE
To maximize HygroPro
II
performance, Panametrics recommends recalibration of the aluminum oxide moisture
sensor on the Replaceable Transducer Element (RTE) every 6 to 12 months. The optimum interval depends on the
specific application. To accomplish this, either return the RTE to Panametrics for recalibration or install a new RTE. The
HygroPro
II
electronics will automatically read and store the calibration data whenever a new or recalibrated RTE is
installed.
Error Code Description On screen Message
E1 Error happens when probe can't be found No Probe Error
E2 When measurement is out of the defined calibration curve range Out of range Error
E3 When measurement is above the defined calibration curve range Over Range Error
E4 When measurement is below the defined calibration curve range Under Range Error
E7 This error happens when the link to the probe is dead No Link Error
E8 The message Probe received does not have the correct CRC Bad CRC Error
E13 The calibration curves were never entered, they have their zero
default entries
No Calibration

sensor
Hygro Sensor Fault
E20 This error happens when there is a hardware fault with the
temperature sensor
Temp Sensor Fault
E21 This error happens when there is a hardware fault with the pressure
sensor
Pressure Sensor Fault
E26 The ADC for the pressure measurement failed ADC Failure
CAUTION!
Be sure to perform the probe cleaning procedure in a well-ventilated area or laminar
fume hood. Observe all necessary safety precautions when handling the cleaning
solvents.
