Relative Humidity Output Calculations - Omega HX93B Series User Manual

Section 6 - Relative Humidity Output Calculations
To calculate % Relative Humidity by measuring the current or voltage output,
use the following formulas.
For current output:
%RH = (Current measured in milliamps – 4) ÷ 0.16
Where:
For voltage output:
Formula: %RH = (voltage measured in volts) x 100

Relative Humidity Output Calculations

4 = offset current in mA.
0.16 = Full scale current limit in percent (%).
a) 1 volt output
%RH = (voltage measured in volts) x 100
b) 5 volts output:
%RH = (voltage measured in volts/5) x 100
c) 10 volts output:
%RH = (voltage measured in volts/10) x 100
