CLEANING THE TEMPERATURE SENSOR PROBE
IMPORTANT: Any particles in front of the sensor’s optics can affect
measurement performance. Therefore it is crucial to
sufficiently clean the sensor. For excessive dust and/or
foreign material buildup on or around the temperature
sensor, it is recommended the instrument be returned to
DICKEY-john Service or authorized service center.
The temperature sensor may require cleaning due to dust buildup and/or
foreign material that has collected around the sensor that could potentially
cause temperature error readings during analysis. It is important the
temperature sensor is visually inspected and cleaned each time a regular
maintenance check of the instrument is conducted.
Tools required for cleaning the temperature sensor probe:
1. One of the below cotton swabs:
– Standard 6” long cotton swab (i.e. McMaster-Carr p/n 7074T12) for
flush sensor
– 6” long, tapered tip cotton swab (i.e. McMaster-Carr p/n 71035T54)
for embedded sensor
