Differential path.
Select thermocouple type (<type> = J|K|T\E\R\S\B\N
USER).
Return thermocouple type (J\K\T\R\R\S\B\N\ USER).
Select thermocouple slope (<n> = slope in V/°C, 0 is
invalid).
Return thermocouple slope (V/°C min = -0.099999; max
= 0.099999; default = 20E-6).
Select reference thermocouple temperature (<n> = refer-
ence temperature in degrees)
Return thermocouple reference temperature in degrees;
min = -273°C; max = 2000°C; default = 0°C).

Path to read digital input port:
Query (read) the digital input port.
3.18.23
Notes:
1. The saved alternate setup is lost when power is cycled, or if *RST or :SYSTem:PRESet is sent over the bus.
2. The default parameter is power line cycle integration; 16.67msec for 60Hz power line and 20msec for 50Hz or 400Hz power line.
3. REPeat is the *RST default parameter and MOVing is the :SYSTem:PRESet default parameter.
4. The *RST default parameter is OFF for all functions. The :SYSTem:PRESet default is OFF for ACI, ACV and TEMP, and ON for DCI, DCV, Ω2 and
Ω4.
5. The *RST default parameter is OFF for all functions. The :SYSTem:PRESet default parameter is ON for ACI, DCI, ACV, DCV, Ω2 and Ω4, and OFF for
TEMP.

Set digital output line #1 true (1 or ON) or false (0 or OFF).
Query digital output line 1.
Set digital output line #2 true (1 or ON) or false (0 or OFF).
Query digital output line 2.
Set digital output line #3 true (1 or ON) or false (0 or OFF).
Query digital output line 3.
Set digital output line #4 true (1 or ON) or false (0 or OFF).
Query digital output line 4.
(Note 1) (Note 2)
Notes:
1. *RST and :SYSTem:PRESet have no affect on the state of the output lines. However, cycling power sets all output lines false (OFF).
2. All :SOURce subsystem commands are non-SCPI.
