Test Analog Output by forcing it to
high, low or midpoint.
(E. G. if Span is 4 to 20, Hi =20mA, Lo=4mA, Mid=12mA)
Set measured attenuation at a known low dewpoint
Set low dewpoint for above attenuation
Calibration Midrange Adjust.
Set dewpoint corresponding to low end of analog output
Factory default is low range of sensor, e. g. -100 C for XTR-100
Factory default is high range of sensor, e. g. +20 C for XTR-100
When locked, instrument parameters can not be changed.
Factory default is locked.
Set dewpoint corresponding to high end of analog output
