EFORM Defining the error output format

EFORM <cr>

The EFORM command is used to define the user specific error output

format for the serial interface. In case of an internal error, the

barometer outputs the message defined with the EFORM command

instead of the normal message defined with the FORM command. If

the EFORM command is not defined, the barometer uses the FORM

command definition with its optional error status fields.

Example of an EFORM definition:

>eform <cr>

? "ERROR" #r #n <cr>

>P <cr>

1002.93 hPa OK (correct operation)

>P <cr>

ERROR (incorrect operation)

Any previous EFORM definition may be removed with the following

command:

>eform * <cr>

DFORM Defining the display format

DFORM <cr>

The DFORM command is used to define the format for the optional

LCD display. The user can define the following fields into the display

format:

pressure quantities P1, P2, P3, P (average)

height corrected pressure HCP (see also page 25)

pressure trend *) TREND (three-hour trend)

pressure tendency A (see page 101 for details)

temperature quantities *) T1, T2, T3

pressure and temperature units UU, UUU, UUUU,UUUUU
