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
Lock or unlock the instrument.

Select Span of Analog output: 0 to 24mA or 4 to 20mA
Select behavior of Analog output during self calibrations or sensor wakeup
NOR - means analog output tracks measurement
FR - means analog output freezes
Factory default is blank, (there is no alternate display).
CAUTION! These are set properly at the factory with the shipped sensor. Do not modify these settings, unless you are changing the sensor.
