AMBHx(=)
Purpose
Set or read the source for the ambient humidity measurement. Also optionally sets the
USER defined measurement.
Syntax “AMBHx=source,
meas”
“AMBHx=source”
“AMBHx”
Default INTERNAL
Argument
x:
The setup number from 1 to 19. See the SETUP command.
Setup 21 is reserved for remote communication use only.
Source:
The measurement source. This can be INTERNAL, DEFAULT
(normal) or USER.
Meas:
The current measurement used. This can only be set if the
source argument is USER. If specified, the limit for this
argument is 0 to 100 %.
Remarks
PG7000 has an on-board humidity sensor that can be used as the source of ambient
humidity values in calculations. You may also request that another source be used for
this measurement.
The measurement source can be the internal sensor, a user defined fixed value, or a
normal value. The SETUP function allows 19 separate source configurations for the
various SETUP variables to be saved in 19 files. The SETUP command selects which
of the files to make active. Setup number 1 is restricted as INTERNAL only to serve as
a manufacturer’s fixed Setup, and cannot be changed.
Example Typical
command:
Typical reply:
“AMBH2=USER,50”
“USER, 50 %”
Typical
command:
Typical reply:
“AMBH9=INTERNAL”
“INTERNAL, 25 %”

AMBPx(=)
Purpose
Set or read the source for the ambient pressure measurement. Also optionally sets the
USER defined measurement.
Syntax “AMBPx=source,
meas”
“AMBPx=source”
“AMBPx”
Default INTERNAL
Argument
x:
The setup number from 1 to 21. See the SETUP command.
Setup 21 is reserved for remote communication use only.
Source:
The measurement source. This can be INTERNAL, DEFAULT
(normal), USER, RPM or the user defined barometer “label”.
Meas:
The current measurement used is kPaa. This can only be set if
the source argument is USER. If specified, the limit for this
argument is 70 to 110 kPaa.
Remarks
PG7000 has an internal atmospheric pressure sensor that can be used as the source of
ambient pressure values in calculations. You may also request that another source be used
for this measurement.
The measurement source can be the internal sensor, a user defined fixed value, the
manufacturer’s fixed default value, an external RPM, or a user defined external barometer.
If an external RPM or a user defined external barometer is chosen, you must setup the
COM2 port to the proper settings. It is also advised to set this up prior to selecting the
setup to make the device active. If you specify “RPM” or the user defined barometer “label”
, then all other barometer source setups set to “RPM” or the user defined barometer will
change to this source, as it is a global selection.
The SETUP function allows 19 separate source configurations for the various SETUP
variables to be saved in 19 files. The SETUP command selects which of the files to make
active. Setup number 1 is the manufacturer’s preferred Setup, and cannot be changed.
The meas argument is used to allow the user to define a fixed value if the source is set to
USER. The reply will always include the source and the meas fields.
Example Typical
command:
Typical reply:
“AMBP2=USER,101.g0”
“USER, 101.90 kPaa”
Typical
command:
Typical reply:
“AMBP9=INTERNAL”
“INTERNAL, 98.234kPaa”
