Stopping the continuous output
S
↵
The continuous outputting is stopped with the command
S
. If
outputting is active, this command is not echoed.
Setting the output interval
INTV n xxx
↵
where:
n
= 1 - 255
xxx
=
S
,
MIN
or
H
Sets the output interval when the transmitter outputs measurement
readings. The time interval is used when the continuous output is
active. For example, the output interval is set to 10 minutes:
>INTV 10 min
↵
Output intrv. :
10 min

Setting the ambient pressure for calculations
Turn the internal dip switch
CALIBRATION ENABLED/DISABLED
to
ON-position before setting the pressure and return it to OFF- position
after setting.
