4. REMOTE OPERATION

 

 

 

 

 

 

 

 

 

 

 

 

 

RANGE

 

 

 

 

 

Purpose

Change the active range to the default range of the Hi, Lo or HL Q-RPT. Replies the active

 

 

range full scale, pressure unit and measurement mode.

 

Command

“RANGE Rng

 

 

Query

“RANGE?”

 

 

 

Classic

“RANGE= Rng

 

 

 

“RANGE ”

 

 

 

Default

“RANGE IH”

 

 

 

Rng:

 

“IH” for the Hi Q-RPT

 

 

 

 

“IL” for the Lo Q-RPT

 

 

 

 

“HL” for the HL Q-RPT

 

Remarks

The active Q-RPT must be selected before making changes to settings that are dependent on the

 

 

range. Q-RPTs selected with this command are used with their full default pressure range. The reply

 

 

indicates the active range in psi if the RPM4 is a “US” version or in kPa if the RPM4 is an “SI” version.

 

 

Used as a simple query, the active range is returned, which can be an AutoRanged range or a

 

 

default range (see “ARANGE” cmd).

 

 

Example

Cmd sent:

“RANGE? IL”

(select internal Lo Q-RPT in it’s full default range)

 

(enhanced)

Query reply:

“2.2 psi g,IL”

 

 

Example

Sent:

 

“RANGE= IH”

(select internal Hi Q-RPT in it’s full default range)

 

(classic)

Reply:

 

“1000 psi a, IH”

 

 

Example

Sent:

 

“RANGE”

(request current range)

 

(classic)

Reply:

 

“220 psi a,IL”

 

 

Errors

ERR# 6:

Invalid Rng argument.

 

 

ERR# 29:

The selected Q-RPT is not available.

RATEn

 

 

 

 

 

Purpose

Read the next available pressure rate of change.

 

Query

“RATEn?”

 

 

 

Classic

“RATEn

 

 

 

Optional Suffix

“n”

The active Q-RPT is assumed if no suffix is given.

 

 

 

‘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 if the HL Q-RPT is active

 

Remarks

The next available pressure rate of change in the current pressure unit per second is returned.

 

 

After receiving this program message, the RPM4 replies back with the data once a new pressure

 

 

measurement cycle is complete. This can take up to the current read rate period (1.2 seconds

 

 

by default).

 

 

 

Example

Query sent:

“RATE?”

 

 

(enhanced)

Query reply:

“0.01 kPa/s”

 

 

Example

Sent:

 

“RATE2”

 

 

(classic)

Reply:

 

“0.03 kPa/s”
