ARANGEn

 

 

 

 

 

 

 

 

 

Purpose

Read or set a new AutoRange range to use.

 

 

Command

“ARANGEn Range, unit, mode (,RptLabel)” (set to user defined range)

 

 

 

“ARANGE Q-RPTLabel

(set to Q-RPT default range)

 

Query

“ARANGEn?”

 

 

 

 

 

 

 

Classic

“ARANGEn= Range, units, mode (,RptLabel)” (set to user defined range)

 

 

 

“ARANGE= Q-RPTLabel

(set to Q-RPT default range)

 

Query

“ARANGEn

 

 

 

 

 

 

 

Optional Suffix

“n”

A suffix may be used instead of “RptLabel

 

 

 

 

‘1’

Specify the Hi Q-RPT if the Hi and Lo Q-RPTs are NOT OFF

 

 

 

 

Specify the HL Q-RPT if the Hi and Lo Q-RPTs are OFF

 

 

 

‘2’

Specify the Lo Q-RPT

 

 

 

 

 

 

‘3’

Specify the HL Q-RPT

 

 

 

 

Arguments

Range:

 

 

The AutoRange maximum pressure. Cannot be negative.

 

 

 

Unit:

 

 

The unit of measure of the Range argument.

 

 

Mode:

 

 

The measurement mode of the Range argument:

 

 

 

 

 

“A” for absolute

 

 

 

 

 

“G” for gauge

 

 

 

 

 

 

 

 

“N” for negative gauge

 

 

 

 

 

 

 

 

 

 

 

 

Measured pressure values are returned with “g” to identify measurement

 

 

 

 

 

mode for both gauge and negative gauge measurement modes.

 

 

 

RptLabel:

 

One of the Q-RPTs that is available.

 

 

(optional)

 

 

“IH”:

Hi Q-RPT if the Hi and Lo Q-RPTs are NOT OFF. HL Q-RPT if

 

 

 

 

 

 

the Hi and Lo Q-RPTs are OFF.

 

 

 

 

 

“IL”:

Lo Q-RPT

 

 

 

 

 

 

 

 

“HL”:

HL Q-RPT.

 

 

 

 

Remarks

The ARANGE command is used to define an RPM4 range by specifying a desired unit of

 

 

 

measure, measurement mode and maximum pressure, and have the RPM4 pick the best

 

 

available Q-RPT and make adjustments to optimize operation in that range.

The optional suffix or the “RptLabel” argument can be used to specify which Q-RPT you wish to use for the AutoRange range instead of allowing the RPM4 to pick the best Q- RPT. By using this option you can override the internal logic that picks the most suitable Q- Q-RPT. This Q-RPT specified must be valid for the maximum pressure and measurement mode specified.

The reply indicates the current range data, including the Q-RPTLabelused for the range.

If “inWa” is specified for the unit, the temperature reference can be given after the unit text (“inWa4”, “inWa20” or “inWa60” corresponding to inWa at 4 °C, 20 °C or 60 °F). If no number is given, a default of 20 °C is assumed. There is no indication of the temperature reference in the reply.

 

If you just specify the Q-RPTLabelwithout any other arguments, the Q-RPT specified will

 

become active in it’s last range and settings. The previously set unit and measurement

 

mode for the Q-RPT specified will become active.

Example

Cmd sent:

“ARANGE?”

(read the current range in the current units)

(enhanced)

Query reply:

“100.00, psi, A, IH”

 

Example

Cmd sent:

“ARANGE”

(read the current range in the current units)

(classic)

Query reply:

“100.00, psi, A, IH”

 

Example

Cmd sent:

“ARANGE? 250, inWa4, G (range of 250 inWa @ 4 °C in gauge mode)

(enhanced)

Query reply:

“250.00 inWa, G, IH”

(Lo Q-RPT is used)

Example

Cmd sent:

“ARANGE=500, kPa, G

(range of 500 kPa in gauge mode)

(classic)

Query reply:

“500.00 kPa, G, IL”

(Lo Q-RPT is used)

Example

Cmd sent:

“ARANGE2 50, psi, A

(range of 50 psi in absolute mode on

(enhanced)

 

 

the Lo Q-RPT)

 

Query reply:

“50.000 psi, A, IL”

(No reply if GPIB-488)

Example

Cmd sent:

“ARANGE IH

(Hi Q-RPT’s prev range made active)

(enhanced)

Query reply:

“500.000 kPa, A, IH”

(No reply if GPIB-488)

 

 

 

Errors

ERR# 6:
