START_STOP, START_STOP? – Memory Location Start and Stop
Addresses for the Sequence Function
Menu
Function
The start and stop addresses of the sequence to be executed are
defined with the START_STOP command. The STOP address
must be equal to or greater than the START address.
i is an optional parameter which addresses the setup memory (1
to 12) to which the START-STOP values will be written, and from
which they will be read.
Setting Command
Syntax: START_STOP n1,n2(,i)
Value range: 1 ≤ n1 ≤ n2 ≤ 1536
Default setting
or after RESET (*RST):
1.1
Query Command
Syntax: START_STOP? (i)
Sample response string: START_STOP n1.n2
STORE, STORE? – Transferring Parameters Directly to Memory
(Menu – in sequential order of entry)
Function
This command is used to write the USET, ISET, TSET and FSET
parameters directly to a memory location in order to set up a
sequence. The parameters must be entered one after the other
via the edit menu.
Setting Command
Syntax: STORE n,w1,w2,w3,txt
Parameters List
Query Command
Syntax: STORE?
Syntax: STORE? n
Syntax: STORE? n1,n2
Syntax: STORE? n1,n2,tab
The response includes the entire parameter set for each memory
location: STORE n,w1.w2.w3.txt
Parameters List
Depending upon which query command is selected, one of the
following responses is be generated:
TDEF, TDEF? – Default Time for SEQUENCE Function
Menu
Function
The TDEF parameter setting defines the dwell time default setting
for a voltage-current value pair to be recalled.
TDEF is used instead of TSET if TSET has not been set to any
specific value, but rather to 0 [s].
Note: Use of TDEF is advantageous if one or several identical
dwell times occur within a given sequence whose values need to
be changed frequently.
i is an optional parameter which addresses the setup memory (1
to 12), to which the TDEF value will be written, and from which it
will be read.
Setting Command
Syntax: TDEF w(,i)
Value range: 0.001 ≤ w ≤ 65.535 [s]
Default setting
or after RESET (*RST): 0.001
Query Command
Syntax: TDEF? (i)
Sample response string: TDEF w
TIMEDATE, TIMEDATE? – Programmable System Clock (RTC)
Menu
Function
System date and time in accordance with ISO 8601 can be
entered to the device with this command. The date entered here
is used for device balancing (ADJUST command).
Setting Command
Syntax: TIMEDATE yyyy-mm-ddThh:mm:ss
Default setting
or after RESET (*RST): Remains unchanged
Query Command
Syntax: TIMEDATE?
Sample response string: TIMEDATE yyyy-mm-ddThh:mm:ss
TIMEDATE 2007-10-01T08:00:05
The specified format must be adhered to:
yyyy: year (2000 ...)
– Delimiter (“–”)
mm: month (01 ... 12)
– Delimiter (“–”)
dd: day (01 ... 31)
T: delimiter (“T”)

This parameter is identical to the setting options
for the FSET command.
Command Value Range Meaning – Response
Store? Query contents of a memory range from the start
address to the stop address of the current sequence
Store? n n =
1 to 1536
Query contents of memory location n
Store? n1,n2 n1, n2
= 1 to 1536
n2 ≥ n1
Query contents of a memory range from address n1
to address n2
Store? n1,n2,tab n1, n2
= 1 to 1536
n2 ≥ n1
Query contents of a memory range from address n1
to address n2
