78 Chapter 6 Calibration
g. Input the second actual (measured) voltage as in Step e.
h. Once the actual voltage value is entered via the
LAS:LDV
command,
the 8000 leaves the current calibration mode.
If, at any time prior to the second
LAS:LDV,
a command other than
LAS:LDV
or
LAS:CAL:LDV?
is sent to the 8000, the 8000 will
cancel the calibration mode and then process the command(s). The
*
OPC?
query may be used to determine when the calibration is
completed.
The operation complete flag (bit 0 of the Standard Event Status
Register) may be used to trigger an interrupt. This type of interrupt is
enabled by setting bit 0 of the Service Request Enable register and
using the
*OPC
command.
