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
