6.2 CalSet
The instrument may be checked against a known moisture level, for example a reference
standard, such as a chilled mirror hygrometer or a psychrometer using the function
CalSet. This procedure is particularly useful when calibrating a Blue Spot sensor (-80°C to
+ 20°C) where the wettest end of the range is usually above normal ambient conditions.
For the CalSet procedure the user must enter the dewpoint of the gas the sensor is
exposed to. Using the current calibration curve, the software calculates the target gain at
this point.
