aXSH!
Get stage height
value
Stage can be checked by issuing an M command.
Returns the value in current units.
value
If P=nnn.n stage value is set to the input number
aXSH10!a
If P=Z the stage offset is set to zero (does not zero the
stage reading, only the offset).
The value range P is from 0.100 to 999.999 (inclusive).
Once the slope is set using this command, the units are
considered “custom” and the Bubbler’s screen will
display “cu” in the Units field of the Set Stage screen.
This is useful when the site requires the slope to be a
non-standard value. See X command aXSUP! for the
built-in list of options.
aXSOP!
psi
Set stage offset in
psi
These commands are used when swapping a
Bubbler and it is desired for the new installation to use
the previously set offset.
Before swapping the Bubbler, use the “get offset”
command and ensure the response is recorded.
Once the Bubbler is swapped, use the “Set Stage
Offset” command. Replace P with the value returned
from the “Get Stage Offset” command from the
previous Bubbler.
Note that, although this command uses psi, the offset
displayed on the Bubbler’s screen and returned as part
of an M command will be in the selected measurement
units, not psi.
Appendix C contains a table of useful conversions from
depth to psi for reference.
aXSP!
Get period for
samples in seconds
Returns sample period (averaging duration). The stage
value is an average of the number of samples taken
over the specified sample period (averaging duration).
Each sample takes approximately 2 seconds.
The sample period range is from 2 – 60 seconds. The
default setting is 8s.
