CONF: DEV(?) <DNPD>
This command defines maximal allowed deviation for continual regulation in functions CURR
(current) and POW (power).
<DNPD>
Parameter represents allowed deviation expressed in %.
If query is sent, the instrument returns the value of deviation using standard exponential
format. Example: 1 % is returned as 1.000000e+000.
Example:
Deviation 2%:
CONF:DEV 2
SYSTem subsystem
The subsystem enables to control various functions from the MENU.

:REMote
:RWLock
:LOCal
SYST:ERR?
Query the instrument's error queue. Detected errors are placed in the queue. This query
returns the first error from the queue. The queue is type "first in, first out". The error is
deleted after reading.
The response is in the form of 'String Program Data', and consists of two elements: a code
number and error message.
If all errors are read the instrument returns message 0,"No Error".
In case of overflow the error queue the last error in the queue is –350,"Queue overflow".
Also the earliest errors remain in the queue, and the most recent error is discarded.
Example:
SYST:ERR?
Error Queue
The Error Queue stores error messages. They are placed in a "first in, first out" queue. The
queue is read destructively using the query command "SYSTem:ERRor?" to obtain a code
number and error message. The query "SYSTem:ERRor?" can be used to read errors in the
queue until it is empty, when the message "0, No Error" will be returned.
SYST:REM
This command places the instrument in the remote mode for RS232 operation. All keys on

Note:
It is not possible to send or receive data over RS232 when the calibrator is not in remote
mode.
SYST:RWL
This command places the instrument into the remote mode for RS232 operation. All keys on
the front panel are disabled.
