Verifying a Meter in the IEEE-488 Bus
This program selects 10 V dc output, verifies that the Calibrator is set to 10 V, then
triggers a Fluke 45 to take a reading. It displays calibrator output, Fluke 45 reading, and
the meter error in ppm. The program assumes that the Calibrator bus address is 4 and the
Fluke 45 bus address is 1.

Verifying a Meter on the RS-232 UUT Serial Port
This program selects 10 V dc output, verifies that the Calibrator is set to 10 V, then
triggers a Fluke 45 to take a reading. It displays Calibrator output, the Fluke 45 reading,
and the meter error in ppm. The program assumes that the Calibrator uses the IEEE-488
interface with bus address is 4 and the Fluke 45 is on the Calibrator SERIAL 2 TO UUT
port.

Using *OPC?, *OPC, and *WAI
The
*OPC?
,
*OPC
, and
*WAI
commands let you maintain control of the order of execution of
commands that could otherwise be passed up by subsequent commands.
If you had sent an
OUT
command, you can check if the output has settled be sending the
query
*OPC?
. As soon as the
OUT
command has completed (output settled), a “1” appears
