HUMEX
Humex Mode
"OFF” maintains below ambient humidity
(standard Nitro-Watch™ functionality). “ON”
maintains above ambient humidity.

RH CAL
RH Calibration
Turn ON/OFF the calibration algorithm for
the humidity sensor calculation.
Note:
the Nitro-Watch™ sensor operates at
an accuracy of ±1.5% RH without any
calibration required. However calibration
may be performed using the calibration
settings if the user wishes to calibrate based
on a reference device.

A
Calibration
Parameter
-These parameters are coefficients and
intercepts for an equation to calibrate the
RH sensor’s readings and compensate for
measured discrepancies. If RH
CALIBRATION is ON, allows cubic
equations for A term.
-If OFF, then skip.
