(Measurement Value command) Shows the last value of the thermocouple temperature
or scope impedance measurement. The unit shows the status of the indication.
Parameter: (Optional) Units to return
Responses: 1. (Float) Measured temperature
2.

OVER
(value is over or under capability),

(open thermocouple),
or
NONE
(wrong mode or no measurement)
Example:
VAL?
shows
0.00E+00,NONE
Shows
0
and
NONE
when there is no recent measurement because the Calibrator is not in
a measurement mode, or because no measurement was made.

(Thermocouple Measurement Voltage command) Shows the last value of the
thermocouple temperature measurement in volts. If the last measurement was an overload
or open thermocouple condition, or there is no measurement, shows 0E+00.
Responses: <measurement value in volts>
(valid measurement)
0E+00
(overload, open TC, or no measurement)
Example:
VVAL?
shows
1.1047E-03
(1.1047 mV, equivalent to 50 °C with type
K thermocouple and TC reference = 23.0 °C

(Wait-to-Continue command) Prevents more remote commands from being done until all
previous remote commands have been done. For example, if you send an
OUT
command,
you can cause the Calibrator to pause until the output has become stable before you
continue on to the subsequent command if you follow
OUT
with a
*WAI
command. The
*WAI
command is useful with overlapped command. This prevents the Calibrator from
processing other commands until the overlapped command is processed.
Example:
*WAI
Process all commands that exist before you continue.

(Waveform command) Sets the waveforms for ac outputs. If the Calibrator is sourcing
one output, one parameter is necessary. If the Calibrator is sourcing two outputs, two
parameters are necessary or one parameter to set the waveform to the two outputs.
Waveform selections are SINE (sine wave), TRI (triangle wave), SQUARE (square
wave), TRUNCS (truncated sine wave), or NONE (waveform does not apply).
Parameter:
<1st waveform> , (SINE, TRI, SQUARE, TRUNCS, NONE)
<2nd waveform> (SINE, TRI, SQUARE, TRUNCS, NONE)
Example:
WAVE SINE,SQUARE
Set the waveforms for a dual output to Sine wave on the primary output (Calibrator front
panel NORMAL terminals) and Square wave on the secondary output (front panel AUX
or 20A terminals).
