expressed in scientific notation.

and where is one of the following:

FAR

°F

CEL

°C

OHM

Ohms

V

DC volts (thermocouple millivolts)

OVER

measurement is over or under range

NONE primary display is presently set to a source mode

or

one of the pressure units listed with the PRES_UNIT?
command

Example:

VAL?

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

IEEE-488

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.

Parameter:

Response:

Example:

OUT 1.1 V

*WAI
OPER
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

IEEE-488

RS-232

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:

for RTD ohms, thermocouple millivolts, or a pressure module
that does not measure absolute pressure

is barometric pressure for absolute pressure modules,
expressed in the currently selected pressure units

Response:

Example:

ZERO_MEAS

If thermocouple millivolts are currently selected, this example zeros the
offset.
