Show User Calibration Coefficients

Use the L command to view the current user calibration coefficients on

the serial line. This command is useful for checking if non-factory

adjustments have been applied for humidity and temperature

measurement.

L<cr>

The output values are as follows:

- RH offset and gain: corrections to RH measurement. These values

change when you calibrate and adjust the humidity measurement.

- T offset and gain: corrections to T measurement. These values change

when you calibrate and adjust the temperature measurement.

For more information on how the adjustments affect these coefficients,

see section Adjustment Points on page 55.

Example (shows default values, no user adjustment done):

RH offset : 0.00000000E+00

RH gain : 1.00000000E+00

T offset : 0.00000000E+00

T gain : 1.00000000E+00

Set User Calibration Coefficients

Use the LI command to enter values for offset and gain coefficients for

on the serial line. Useful for restoring the factory defaults, or some earlier

state of user adjustment.

CAUTION

Use this command only to restore values you have previously written

down based on the output from the L command, or to restore the default

offset and gain.

LI<cr>

After you enter the command, you will be prompted to enter new values

for the coefficients. The default offset is zero (0), default gain is one (1).

Example (shows user adjusted offset values, overwrites them with 0):

RH offset : -4.35084105E-04 ? 0

RH gain : 1.00000000E+00 ?

T offset : -1.62982941E-02 ? 0

T gain : 1.00000000E+00 ?
