pressure quantities
P1, P2, P (average), PD
(difference)
pressure trend *) TRE (three-hour trend)
pressure tendency A (three-hour tendency)
temperature quantity of PT100
and HMP45D sensor heads *)
T
temperature quantity
of HMP45
TH
relative humidity RH
units U, UU, UUU, UUUU, UUUUU
serial number of the transmitter SN
error status ERR (three characters)
stability indicator OK (uses three characters)
number fields n.m where: n = 0 - 9, m = 0- 9
text fields within “ “ characters
*) The PTU200 transmitter cannot output + sign for pressure trend or
temperature reading; a space is output instead.
Any previous DFORM definition may be removed and the original
factory setting restored with the following command:
>dform *
