CAUTION Before using the calibration and adjustment commands, read through Calibration and adjustment.
Table 1. Cdate command
Syntax Description
cdate<cr> Show currently stored calibration date.

cdate [yyyymmdd]<cr>

Set a new calibration date.

yyyymmdd = Date in format year (yyyy) month (mm) date (dd).

Example (set calibration date to June 1st, 2018):

cdate 20180601
Cal. date : 20180601
Table 2. Crh command
Syntax Description
crh<cr>

Start the two-point humidity calibration and adjustment sequence. For a full adjustment procedure, see Two-point humidity calibration and adjustment using computer and HMK15 Humidity Calibrator.

crh [ref]<cr>

Perform a one-point adjustment at the current relative humidity. The device calculates the required correction based on the reference humidity that you enter.

ref = the correct relative humidity at the environment where the sensor is now.

Example :

crh
RH : 11.5379 1. ref ? 11.3
Press any key when ready ...
RH : 74.9684 2. ref ? 75.4
OK
Table 3. Crhclr command
Syntax Description
crhclr<cr> Clear the current user adjustment for humidity. Factory calibration remains.

Example:

crhclr
OK
Table 4. Ct command
Syntax Description
ct<cr>

Start the two-point temperature calibration and adjustment sequence. For a full adjustment procedure, see Two-point temperature calibration and adjustment using computer.

ct [ref]<cr>

Perform a one-point adjustment at the current temperature. The device calculates the required correction based on the reference temperature that you enter.

ref = the correct temperature (in degrees Celsius) at the environment where the sensor is now.

Example :

ct
T : 22.9424 1. ref ? 23.0
Press any key when ready ...
T : 54.9873 2. ref ? 55
OK
Table 5. Ctclr command
Syntax Description
ctclr<cr> Clear the current user adjustment for temperature. Factory calibration remains.

Example:

ctclr
OK
Table 6. Ctext command
Syntax Description
ctext<cr> Show currently stored calibration text.
ctext [sss]<cr>

Set a new calibration text.

sss = Text string, maximum length 24 characters.

Example (set calibration text to Lab1/John):

ctext Lab1/John
Cal. info : Lab1/John
Table 7. Fcrh command
Syntax Description
fcrh<cr> Start the two-point humidity calibration and adjustment sequence. If you have changed the humidity sensor of the device yourself, you must perform a two-point humidity calibration and adjustment using this command. Follow the procedure in Two-point humidity calibration and adjustment using computer and HMK15 Humidity Calibrator.

Example:

fcrh
RH : 11.3143 1. ref ? 11.3
Press any key when ready ...
RH : 75.0012 2. ref ? 75.4
OK
Table 8. L command
Syntax Description
l<cr> Show the current offset and gain parameters for user adjustment. This command is useful for checking if user adjustments have been applied for humidity and temperature measurement.

Example (shows default state without user adjustments - offset is 0 and gain is 1 for both humidity (Cp offset and gain) and temperature):

l
Cp offset : 0.00000000E+00
Cp gain : 1.00000000E+00
T offset : 0.00000000E+00
T gain : 1.00000000E+00
Table 9. Li command
Syntax Description
li<cr>

Enter values for offset and gain parameters for user adjustment. Useful for restoring some earlier state of user adjustment.

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.

Example (shows adjustment has been applied to humidity measurement offset, overwrites it with 0):

li
Cp offset : -1.50922060E-01 ? 0
Cp gain : 1.00000000E+00 ?
T offset : 0.00000000E+00 ?
T gain : 1.00000000E+00 ?
