10.2.1.7 *OPC? *OPC?
SCPI: *OPC? /qonly/
SHORT: *OPC?/qonly/
ID: n/a Mode: all
Type: char Suffix: n/a
Value: ‘1’ List: n/a
Unit: n/a Group: n/a
Causes the device to place a „1“ (=31h) in the output queue, when all pending selected device
actions have been finished (=operation complete). This is independent from the output format!
10.2.1.8 *PRE *PRE
SCPI: *PRE <NRi>
SHORT: *PRE <NRi>
ID: n/a Mode: all
Type: long int Suffix: n/a
Value: 0...65535 List: n/a
Unit: n/a Group: n/a
Used to set up or read out the Parallel Poll Enable Register
10.2.1.9 *RST *RST
SCPI: *RST/nquery/
SHORT: *RST/nquery/
ID: n/a Mode: all
Type: n/a Suffix: n/a
Value: n/a List: n/a
Unit: n/a Group: n/a
This performs a device reset. A lot of internal settings (like measuring mode, ranges, ...) are set
to their default values. In this chapters the default value is indicated by ‘[*RST Default value]’.
All time dependent measurements are stopped (energy, flicker, harmonics).
The interface and it’s parameters are not reset! If you want to reset it, please use a BREAK
with RS232 interface or a ‘device clear’ with IEEE interface.
Hint
The execution of this command can take up to several seconds. The LMG works internally
with a watchdog protection. To prevent that the watchdog becomes active, the ‘*RST’
command should be send as the only command in a message. Just the ‘*OPC?’ can be added to
get a feedback, if the command has finished (‘*RST;*OPC?’). In this case wait until the ‘1’
returns before sending the next commands!
