Technical data

ISET_MAX - current setting to
a) 2.3ØØ A for the operating mode INDEPEND and A-B TRAC
b) 4.6ØØ A for the operating mode A-B PAR
ISET? - Current setting A xxxxx is saved in the output buffer.
IOUT? - Measured current value A xxxxx is saved in the output buffer.
Note
: When the selected source works off a constant voltage source and the
command ISET? is transmitted, the displayed current represents the value
of current limit.
Activation of source outputs A and B
OUT_ON - Outputs of sources A und B are active.
OUT_OFF - Outputs of sources A und B are not active.
OUT? - Current state OUT_ON or OUT_OFF of source outputs A and B is
saved in the output buffer.
Parameter control of sources A and B (see 6.5)
PROT_LIM - setting of the protective function LIMITING
PROT_CUT - setting of the protective function CUT-OUT
PROT? - Current protective function PROT_LIM or PROT_CUT of sources A
and B is saved in the output buffer.
Saving and loading of parameter pre-set
*SAV x - saving of parameters at the memory places (x) from Ø to 5
*RCL x - loading of parameters at the memory places (x) from Ø to 5
7.5 Measurement by Remote Control
For external control of the unit the respective connecting cable of the system interface GPIB
or RS-232C has to be connected before switching on the operating voltage. After switching
on the power supply unit is in starting position and can receive commands. The remote
control is displayed on LED REMOTE [14].
It should be noted that single commands or groups of commands have to be separated by a
semicolon (ASCII: “;” = 59) and ended by the end character. Certain commands or messages
can contain parameters or measuring results which are clarified by a separation character.
Single commands can be written one after the other in one command line, the length of which
may not exceed 64 characters. In case errors occur, the command sequence is ignored and
error INP. BUFFER FULL is indicated.
