shown below in bold type. (To return to the factory defaults, see the FORMAT SETUP
command.)
Responses: <baud rate value>, 300, 600, 1200, 2400, 4800, 9600
<flow control>, XON (xon/xoff), NOSTALL (none), RTS (rts/cts)
<number data bits>, DBIT7 (7 bits) or DBIT8 (8 bits)
<number stop bits>, SBIT1 (1 bit) or SBIT2 (2 bits)
<parity> PNONE (none), PODD (odd),PEVEN
(even)
Example: UUT_SET? returns 9600,XON,DBIT8,SBIT1,PNONE
Returns the parameters for the rear panel SERIAL 2 TO UUT serial port, as shown, when
set to the factory default values.
VAL?
Sequential Overlapped
Coupled
IEEE-488 RS-232

x
(Measurement Value command) Returns the last value of the thermocouple temperature,
pressure, or scope impedance measurement. The unit returns indicates the status of the
reading.
Parameter: (Optional) Units to return
Responses: 1. (Float) Measured temperature or pressure
2. (Character) CEL, FAR, OHM, F, PSI, MHG, INHG, INH2O,
FTH2O, MH2O, BAR, PAL, G/CM2, INH2O60F,
OVER (value is over or under capability),
OPENTC (open thermocouple),
or NONE (wrong mode or no measurement)
Example: VAL? returns 0.00E+00,NONE
Returns 0 and NONE when there is no recent measurement either because the Calibrator
is not in a measurement mode, or because no measurement has been made yet.
VVAL?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Thermocouple Measurement Voltage command) Returns 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, returns 0E+00.
Responses: <measurement value in volts> (valid measurement)
0E+00 (overload, open TC, or no measurement)
Example: VVAL? returns 1.1047E-03 (1.1047 mV, equivalent to 50 °C with type
K thermocouple and TC reference = 23.0 °C
*WAI
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x xx
x
(Wait-to-Continue command) Prevents further remote commands from being executed
until all previous remote commands have been executed. For example, if you send an
OUT command, you can cause the Calibrator 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 Calibrator from
processing other commands until the overlapped command is processed.
Example: *WAI
Process all existing commands before continuing.
