HELP? <ARBITRARY
ASCII RESPONSE
DATA> X X Returns the available command headers.
FILE? <String> X X Returns the actual working file.
SAVE <String> X Stores the current working file under the name
<String> .
Sets bit 1 at the “Device Dependent Register” in
case of an error.
Example.: SAVE 'C:\ABC.XML'
LOAD <String> X Loads the actual working file. If the file does not
exist the “Device Dependent Register” Bit 1 will
be set.
Example.: LOAD 'C:\ABC.XML
SRQ
SRQ? ON
OFF X X X X Only functional if the IEEE 488 interface is used.
In the 'ON' state a Service Request is initiated as
soon as a bit changes in the Serial Poll Byte.
7.8.3 System control commands
There are commands that can be activated only if the high voltage is switched off . The RHE (Remote
High Voltage switched ON) and RHA (Remote HV switched OFF) columns give information about the
necessary states of the system. If a command is executed in an incorrect state, bit 0 in the DDR
Register is set.
Note: LA = Local Answer
RA = Remote Answer
LS = Local Set
RHE = Remote HV ON Set
RHA = Remote HV OFF Set

REFV?
<Nx> X X X X Sets or returns the target value of the
voltage. The value should be between 0
V and the maximum set voltage,
otherwise the EXR Register is set to 5
Example : ACS:REFV 8E3 will set the
voltage to 8 kV.
