*) The PTB220 barometer cannot output + sign for pressure trend or

temperature reading; a space is output instead.

There are two rows containing 16 characters each; the user can define

a maximum of 32 characters to be displayed. The field definitions are

defined in successive order so that the first 16 characters will be

displayed on the first row and the next characters on the second row.

The factory setting for the display format includes the pressure

reading and the stability indicator:

ENTCL

Any previous DFORM definition may be removed and the original

factory setting restored with the following command:

>dform * <cr>

Example of setting the display format to show pressure, stability

indicator, pressure trend and pressure tendency:

>dform <cr>

4.2P""UUUUU OK #r #n

?""4.2P""UUUOK"trend " 2.1 TREND""UUU""A

<cr>

In this case, the display will look similar to the following:

ENTCL

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 112 113
