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
