molbox™ RFM™ OPERATION AND MAINTENANCE MANUAL
© 1998-2007 DH Instruments, a Fluke Company Page 106
ALLR
Purpose Read the next measurement of molbloc flow, the RFM upstream
and downstream RPT pressure values, the molbloc
temperature, and the optional microrange RPT pressure.
Syntax “ALLR”
Remarks The next available measurements are replied. This can take up
to 1 second, since the molbox RFM 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, micropres”
“RDY” is the flow ready field. The ready status is covered in the
“SR” command.
“flow” is the current measured flow and flow units.
“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.
“micropres” is the optional microrange RPT pressure
measurement and units.
Example Command:
Reply:
“ALLR”
“R 1.2 sccm,97.697 kPa a,97.685 kPa a,97.708
kPa a,17.97C,0.0261 kPa”
Errors ERR# 27: One of the RPTs (transducer) is not functioning.
See Also “SR”, “READYCK”, “DP”, “HIP”, “LOP”, “FR”
BEEPER(=)
Purpose To actuate the internal beeper for half of a second.
Syntax “BEEPER”
“BEEPER=freq”
Arguments freq: The desired frequency from 250 to 10 000 Hz. If
a frequency is not indicated, the current default
frequency will be used.
Remarks The internal beeper is also used to indicate overpressure
conditions, which will over-ride this command.
Example Command:
Reply:
“BEEPER=5000”
“5000”
Errors ERR# 7: The frequency is invalid.
