Ice Buildup and Purge Procedure (4180 Only)

3.4.1

Icing Warning

At the factory, the instrument calibration is done with the target free of any ice or
moisture. Ice or moisture on the target changes the target's emissivity and apparent
temperature. If there is any ice or moisture (even though it is a slight amount) on the
target, the display temperature accuracy is invalid. In addition, ice buildup can damage
the surface coating causing the radiometric calibration to drift.
The user of the IR Precision Calibrator should always avoid ice buildup. To facilitate
this, a cover with a purge inlet is provided with the 4180. It is recommended that the
target cover be used at any set-point below the dew point. Depending on the ambient
humidity of the environment where the target is used, the dew point can be as high as
the ambient temperature of that environment.
3.4.2

Purge Procedure

Use of the cover allows the target to be used at temperatures below the dew point. The
target is less likely to form ice while the target is covered. The target cover is provided
with a purge inlet to further prevent ice buildup. To use the purge, the user will need
a 6mm (0.25 in) outside diameter tube. Connect tubing to the purge inlet on the target
