Table 1. DSEL command
Syntax Description
dsel [q1 q2]<cr>


q1 q2
Measurement parameters to be shown on the transmitter display 1

Syntax for single-parameter transmitters:

dsel [q]<cr>


Parameter to be shown on the transmitter display
After you have defined the measurement parameters with the calcs command, use the dsel command to show or set the displayed parameters. The number of parameters determines the display mode (that is, one or two rows). If one parameter is given, the display switches to one-row mode. If two parameters are given, the two-row mode is used. Valid parameters are: RH, T, TD, TDF, A, X, H, TW, PWS, and PW.
1. quantity        : RH
2. quantity        : T
>dsel rh t
1. quantity        : RH
2. quantity        : T
>dsel t
1. quantity        : T
Table 2. FORM command
Syntax Description
form <format><cr>
where format is a formatting string that consists of one of the following fields:
String constant
Value length modifier. x is numbers before dot and y is numbers after dot.
Unit field length. U…U format is also supported.
Measurement parameter name (for example, rh, t, or td)
#t or \t
#r or \r
Carriage return
#n or \n
Line feed (new line)
After you have defined the measurement parameters with the calcs command, use the form command to set the output format for the send and r commands.
  • Parameter must be after x.y and Ux modifiers.
  • There must be a space between parameters, #r#n or \r\n is not supported.
  • Max. string length is 80 characters.
  • If the Ux parameter is not used, unit is not displayed.
>form "RH= " 3.2 U2 rh #r #n
RH= 32.16 %
>form "t=" 4.1 U3 t \t "rh=" 3.2 U2 rh \r \n
t=  22.5 'C        rh= 29.12 %
>form "t=" 4.1 U3 t \t "rh=" rh \r \n
t=  22.3 'C        rh=  29.5%
>form 3.2 UUU "RH=" rh \t "T=" t \r \n
RH= 27.99  %       T= 23.34 'C
>form 3.3 rh " " t \r \n
26.740  23.660
>form "->" "RH=" 3.2 U2 rh " " "T=" 3.1 U3 t #r #n
->RH= 27.79 % T= 23.4 'C
Table 3. HELP command
Syntax Description
help<cr> Use the help command to display the list of available commands.
Table 4. ERRS command
Syntax Description
errs<cr> Use the errs command to display the currently active error codes. For troubleshooting active errors, see Error codes.
Example (no active errors):
No errors.
Table 5. SAVE command
Syntax Description

Use the save command to save changed settings to the transmitter FLASH memory. Most settings have to be saved or the changes are lost at the next reset or power down.

The smode command saves the new serial mode immediately, and a separate save command is not needed.

The probe calibration commands (crh, ct, crhclr, ctclr) store the parameters into the probe's memory automatically without a separate save command.
Saving settings...done
Table 6. RESTORE command
Syntax Description

Use the restore command to restore saved settings from transmitter FLASH memory to RAM. All unsaved changes will be lost.

Restoring default settings...done
Table 7. RESET command
Syntax Description

Use the reset command to reset the transmitter. Upon reset or power-up, the transmitter enters the serial mode that has been set with the smode command.

After a reset, the configuration is loaded from FLASH memory. This configuration can be altered by saving different settings with the save command.

Example: Transmitter set to serial mode STOP, will output transmitter software version at reset

Type "help" for command list
Table 8. FRESTORE command
Syntax Description

Use the frestore command to restore the factory settings to the transmitter. All user settings, including the user-performed calibration corrections, will be lost. The transmitter will revert back to the factory calibrated settings.

Note that this only returns the factory settings of the transmitter and not of the interchangeable probe (see Table 2 and Table 4).

Restoring factory defaults...done
Table 9. UNIT command
Syntax Description
unit [metric/non_metric]<cr> Use the unit command to show or set the output unit (metric or non-metric).
Unit                : METRIC
>unit non_metric
Unit                : NON_METRIC
1 Measurement parameters are referred to as 'quantities' in the transmitter's software.
