8. 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 miliamps – 4) ÷ .16
EXAMPLE:
(11.04 mA – 4) ÷ .16 = 44% RH
For voltage output:
% RH = (Voltage measured in volts x 100)
EXAMPLE:
.44 x 100 = 44% RH
