command
Example:

2.137000E+00,V,5.763300E+01,CEL
This example indicates that the isolated measurement is 2.137 volts
and that the primary measurement is 57.633 °C.
*WAI

RS-232
Sequential
Overlapped
This command prevents further remote commands from being executed until all previous
remote commands have been completed. For example, if you send an OUT command,
you can cause the 3001 to wait until the output has settled before continuing on to the
next command if you follow OUT with a *WAI command. The *WAI command is useful
with any overlapped command, preventing the 3001 from processing other commands
until the overlapped command is completed.

FAULT?
This example demonstrates setting the 3001 output to 1.1 volts, waiting
for the output to settle before activating the output and checking if the
sequence of commands completed successfully.
ZERO_MEAS

Sequential
Overlapped
This command zeros a pressure module, the thermocouple mV offset, or the RTD ohms
offset. For detailed zeroing instructions see section 4.3 for RTD ohms, section 4.7 for
thermocouple millivolts, or section 4.9 for pressure.
Parameter:
that does not measure absolute pressure
expressed in the currently selected pressure units
Response:
Example:
ZERO_MEAS
If thermocouple millivolts are currently selected, this example zeros the
offset.
