ALLR
Purpose
Read the next ready/not ready indication, measurement of molbloc flow, the
upstream and downstream RPT pressure values and the molbloc
temperature.
Syntax
“ALLR”
Remarks
The next available measurements are replied. This can take up to 1 second,
since the waits for the next flow measurement before replying. The
reply starts with the flow ready information. Then the flow value is given in the
current flow units. Commas are then used to separate the other measurements in
this order:
“RDY flow, avgpres, uppres, dnpres, temp”.
“RDY” is the flow ready field. The ready status is covered in the “SR” command.
“flow” is the current measured flow and flow units. “-999999” in this field when
using a molbloc-S indicates that the BPR is too low for a correct flow
measurement.
“avgpres” is the average of the upstream and downstream RPTs and units.
“uppres” is the upstream RPT pressure measurement and units.
“dnpres” is the downstream RPT pressure measurement and units.
“temp” is the molbloc temperature and units.

Reply:
“ALLR”
“R 0.00075 slm,97.3844 kPa,97.3945 kPa,97.3743 kPa,
17.97C”
“NRP -999999 slm,97.3844 kPa,97.3945 kPa,97.3743 kPa,
17.97C” (BPR too low)
Errors
ERR# 27 or
28:
One of the RPTs (pressure transducers) is not functioning.

AUTOZERO(=)
Purpose
Read or set the status of the reference pressure transducer (RPT) AutoZ function.
Command
Query
“AUTOZERO=
n
”
“AUTOZERO”
Default
“AUTOZERO=1”
Arguments
n
:
’0’ Autozero OFF
’1’ Autozero ON
Remarks
The “AutoZ” function can be turned ON and OFF. This command sets
the AutoZ status for both of the internal RPTs.
Example
Sent:
Query reply:
“AUTOZERO=1”
“AUTOZERO=1”
Errors
ERR# 6:
The argument was other than a ‘0’ or a ‘1’.

BEEPER(=)
Purpose
To actuate the internal buzzer for half of a second.
Syntax
“BEEPER”
“BEEPER=freq”
Arguments
freq:
This variable has no purpose, but is included for compatibility
with the
DH Instruments
RFM product.
Remarks
The internal buzzer tone is fixed, so the argument serves no purpose.
Example
Command:
Reply:
“BEEPER=1000”
“1000”
