UNITn
Purpose
Read or set the pressure unit of measure.
Command
Query
“UNIT
n
unit (, ref
”)”
“UNIT
n
?”
Classic “UNIT
n
=
unit (, ref
”)”
“UNIT
n
”
Optional Suffix
“n”
A suffix may be used instead of “
RptLabel
”
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Arguments
Unit:
ref:
The text corresponding to the pressure unit of measure.
The optional unit reference temperature only if the unit is “InWa”
Remarks
This program message determines what unit of measure is used to display pressure values. Refer
to Table 6 for a detailed list of the units available and their labels.
If the unit specified is “InWa”, an optional second argument “
ref”
can be set. The “ref” can be 4, 20,
or 60 corresponding to InWa at 4 °C, 20 °C or 60 °F. If this second argument is not given when the
unit is “InWa”, then the reference temperature is assumed to be 20 °C. This can also be added
directly onto the end of the
Unit
argument if desired.
The fifth character of the reply is always ‘g’ for gauge mode. White spaces precede this character
if needed. The temperature reference is added to the reply only if the unit is “InWa”.
The reply includes the measurement mode character in the fifth position, with a ‘g’ indicating gauge
mode.

VER
Purpose
Identify the RPM4-E-DWT, US or SI units, the Q-RPT labels and the software version.
Query “VER?”
Classic “VER”
Remarks
The software version of the RPM4-E-DWT can be read. This is useful for checking for the
presence of the RPM4-E-DWT and for reference purposes. It indicates the internal Q-RPT(s) and
software version.
