GPIB
Purpose Read or set the GPIB interface address.
Command
Query “GPIB addr ”
“GPIB?”
Classic “GPIB= addr ”
“GPIB”
Defaults “GPIB 10”
Arguments Addr: The address of the IEEE-488 (GPIB) interface (1 to 30)
Remarks The GPIB address is changed following the reply of this command. Each device on a GPIB
interface bus requires a unique address.
Example

HEAD
Purpose Read or set the gas head settings.
Command
Query “HEAD height, units, gas ”
“HEAD?”
Classic “HEAD= height, units, gas
“HEAD”
Defaults “HEAD 0, cm, N2”
Arguments height: The height of the test in relation to the RPM4-AD. The value is positive if the test
is above the RPM4, or negative if below the RPM4-AD. The value can be
between - 9999 and 9999. Setting the value to ‘0’ disables the head correction.
units: The height units. This must be “in” or “cm”.
gas: The gas type. This must be “N2”, “AIR” or “HE”. Command is case
sensitive.
Remarks The RPM4-AD can make a gas head correction to allow it to display the pressure at a level other
than the reference level of the RPM4-AD.
Example
(enhanced) Cmd sent:
Query reply: “HEAD? 10,in,N2”
“10, in, N2”
Example
(classic) Sent:
Reply: “HEAD=10,in,N2”
“10, in, N2”
Errors ERR# 2:
ERR# 6:
ERR #7:
The gas text is too long
The height is not within given limits or the unit is invalid.

ID
Purpose Read or set the user defined instrument identification label.
Command
Query “ID string ”
“ID”
Classic “ID= string ”
“ID”
Arguments String: An alphanumeric string up to 12 characters long.
Remarks The user defined ID label can be used to allow the user to “tag” the RPM4-AD with a unique
identifier. This ID is stored in non-volatile memory and cannot be erased by a power failure,
system fault or reset. The ID should not be changed frequently, as the non-volatile memory
may fail after 100,000 write operations.
Example
(enhanced) Cmd sent:
Query reply “ID RPM4-AD #A01”
“RPM4-AD #A01”
(No reply if GPIB-488)
Example
(enhanced) Cmd sent:
Query reply “ID? RPM4-AD #A01”
“RPM4-AD #A01”
Example
(classic) Sent:
Reply: “ID=RPM4-AD #A01”
“RPM4-AD #A01”
Errors ERR# 2 Text argument is too long (more than 12 characters)
