4. REMOTE OPERATION

 

 

 

 

 

 

 

 

 

 

 

 

 

MEM

 

 

 

 

 

Purpose

Read the status from the power-up memory test.

 

Query

“MEM?”

 

 

 

 

Classic

“MEM”

 

 

 

 

Remarks

The RPM4 system memory stores the user settings (units, resolution) and retains them when

 

 

the unit is OFF. On power-up, this memory is checked. If this memory is corrupted, all user

 

 

settings are reset to default , and the MEM status is set to reflect this.

 

Example

Query sent:

“MEM?”

 

(enhanced)

Reply:

“0”

RPM4 data corrupted and was set to factory defaults.

 

 

 

“1” The memory was found to be OK on power-up.

 

Example

Sent:

“MEM”

 

(classic)

Reply:

“MEM=0” RPM4 data corrupted and was set to factory defaults.

 

 

 

“MEM=1” The memory was found to be OK on power-up.

MMODEn

 

 

 

 

 

Purpose

Read or change the active measurement mode.

 

Command

“MMODEn mode

 

 

 

Query

“MMODEn?”

 

 

 

 

Classic

“MMODEn=mode

 

 

 

 

“MMODEn

 

 

 

 

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 and the HL

 

 

 

 

Q-RPT is not active.

 

 

 

 

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

 

 

 

‘2’

Specify the Lo Q-RPT if the HL Q-RPT is not active and measurement

 

 

 

 

mode is not differential.

 

 

 

‘3’

Specify the HL Q-RPT if the HL Q-RPT is active.

 

 

 

 

 

 

Arguments

Mode:

"A"

Absolute mode

 

 

 

"G"

Gauge mode

 

 

 

"N"

Negative gauge mode

 

 

 

“D”

Differential mode (available only for the Hi Q-RPT)

 

 

 

 

 

 

 

 

 

 

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

 

 

 

 

mode for both gauge and negative gauge measurement modes. Differential

 

 

 

 

mode restricts access to settings on the Lo Q-RPT.

 

 

 

 

 

 

 

 

 

Remarks

The measurement mode can also be set using the “UNIT” command but the “UNIT” command

 

 

does not distinguish between gauge and negative gauge in it’s reply, while the “MMODE”

 

 

does. Measurement mode is range specific.

 

Example

Cmd sent:

“MMODE A”

 

(enhanced)

Query reply:

“A”

(No reply if IEEE-488)

 

Example

Cmd sent:

“MMODE? A”

 

(enhanced)

Query reply:

“A”

 

 

 

Example

Cmd sent:

“MMODE=G”

 

(enhanced)

Query reply:

“G”

 

 

 

Errors

ERR# 6:

Invalid argument text.

 

 

ERR# 7:

Abs mode only with altitude units or gauge mode only with gauge Q-RPT.

 

 

ERR#10:

The suffix indicating the Q-RPT is invalid for the current conditions.

 

 

ERR# 20:

Absolute or negative gauge mode not available with gauge Q-RPT.

 

 

 

Absolute Q-RPT with an absolute and negative gauge OFF calibration.

 

 

 

The current range cannot support gauge mode.

 

 

ERR# 53:

Gauge mode range would be negative.

 

 

 

Lo Q-RPT not suitable for differential mode.
