Example: one-point calibration (LiCl reference, 11 %RH):

crh 11

Example: one-point calibration with NaCl reference (75 %RH):

crh 75

Giving the command without parameters starts the two-point calibration.

Remember to allow the humidity to stabilize for 20 - 40 minutes after

changing the reference.

Example: two-point calibration with LiCl (11 %RH) and NaCL (75

%RH) references:

crh

RH : 11.2684 1. ref ? 11

Press any key when ready ...

RH : 75.0612 2. ref ? 75

Clear Adjustment of RH Measurement

Use the CRHCLR command to clear the adjustment of RH measurement

that has been done using the CRH command.

CRHCLR<cr>

Example:

crhclr

Calibrate Temperature Measurement

Use the CT command to perform a one-point or two-point temperature

(T) calibration. One-point calibration adjusts the offset for the

measurement, two-point calibration adjusts offset and gain.

CT [reference]<cr>

When performing a one-point calibration, you need to place the probe in

a single temperature reference and wait for 20 – 40 minutes for the

temperature to stabilize. To apply the adjustment, enter the CT command

with the reference temperature as a parameter.
