XPRES Setting the pressure for pressure
compensation and for ppm calculations
temporarily
XPRES pppp.pp <cr>
pppp.pp = absolute pressure (hPa)
The function and format of XPRES are the same as those of the PRES
command except that by using XPRES, the setting is valid only until a reset is
given, or power is turned off or pressure is set to zero using XPRES. After this,
the pressure stored using command PRES is valid again.
CDATE Entering calibration date
CDATE xxxxxx <cr>
xxxxxx = calibration date (000101...991231)
When the latest calibration date has to be kept in memory, it is entered as fol-
lows:
>CDATE 940506 <cr>
If the command is given without the date, the transmitter outputs the latest
calibration already in memory.
>CDATE <cr>
940420
The date can be given in any format; however, the maximum number of digits
is six.
DATE Setting the date
DATE <cr>
For example, to enter a new date:
>DATE <cr>
Current date is 1993-01-30
Enter new date (yyyy-mm-dd) : 1993-06-12 <cr>
When the current date is asked, the new date is passed with <cr>.
