XPRES Setting the pressure for mixing ratio and wet bulb

temperature calculations temporarily

XPRES pppp.pp <cr>

pppp.pp= pressure (hPa)

The function and format of XPRES are the same as those of the PRES com-

mand 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 kept in memory, it is entered as fol-

lows:

If the command is given without the date, the transmitter outputs the latest

calibration already in memory.

>CDATE <cr>

The date can be given in any format; however, the maximum number of digits

is six.
