Technical data

DCL (Device clear) - initializing for the communication protocol of the interface
GPIB: - address instruction according to IEEE-488.1
RS-232C: - ASCII: DC4 = 20 (dec.)
Note
: This command must not stand between the first command and the end
character of a command line.
*RST (Reset) - initializing of unit settings of sources A and B
outputs: - disabled
operating mode: - INDEPEND (Independent Mode)
function mode: - CV (constant voltage source)
output voltages: - Ø.ØØ V
output currents: - 2.3ØØ A
protective function: - LIMITING
Note
: After switching on the settings are loaded. Furthermore the commands
DCL, *CLS and OUT_OFF are executed automatically and the contents
of the ESE and SRE register are reset. The bit 7 (PON) of the ESR
register is set on 1.
*TST? (Test) - start of unit tests and saving of results
meaning: Ø - test is successful
1 - test is not successful
*IDN? (Identification) - identification GRUNDIG,PN3ØØ,x,y
with x - production number or Ø
y - software version or Ø
Note
: The command *IDN? must be written at the end of the command line
so that the result is saved in the output buffer.
*CLS
(Clear Status Byte) - initializing (resetting) of ESR, STB and ERR register
ERR? (Error) - reading and resetting of the error messages (see 7.3.3)
DER? - Contents of the DER register are saved in the output buffer.
*WAI (Waiting) - The following commands are executed after completion of
current operation.
*OPC
(Operation Complete) - After completion of current operation the bit 7 (OPC) in the
ESR register is set on 1.
*OPC? - After completion of current operation the number 1 is saved in
the output buffer.
*ESR?; *ESE xxx; *ESE? - reading and setting of the ESR (see 7.3.1.1)
*STB?; *SRE xxx; *SRE? - reading and setting of the STB (see 7.3.1.2)
