[SENSe:]FRESistance[:DC]:FILTer:DIGital[:STATe](?) <n> 
Description  Activates or deactivates the digital averaging filter to improve noise 
immunity for the 4-wire resistance function. This setting is stored in 
volatile memory.
 
Parameters  <n>  =  OFF or 0  Turns the digital averaging filter off. 
      ON or 1  Turns the digital averaging filter on. 
 
Examples  FRES:FILT:DIG ON  Turns the digital averaging filter on. 
Query  FRES:FILT:DIG?  Returns the digital averaging filter setting. (0 = 
OFF and 1 = ON) 
[SENSe:]UNIT:TEMPerature(?) <units> 
Description  Sets the temperature units for the temperature function. This setting is 
stored in volatile memory.
 
Parameters  <units>  =  Cel  Sets temperature units to Celsius 
        Far  Sets temperature units to Fahrenheit 
      Kel  Sets temperature units to Kelvin 
 
Examples  UNIT:TEMP C  Sets temperature units to Celsius. 
Query  UNIT:TEMP?  Returns the temperature units setting. (C = 
Celsius, F = Fahrenheit, and K = Kelvin) 
[SENSe:]ZERO:AUTO <n> 
Description  Activates (default) or deactivates the autozero mode. This setting is stored 
in volatile memory.
 
Parameters  <n>  =  OFF  Turns Autozero mode off. 
      ON  Turns autozero mode on. 
      ONCE  Initiates a zero measurement immediately. 
 
Examples  ZERO:AUTO ON  Turns autozero mode on. 
Query  ZERO:AUTO?  Returns the state of the autozero mode. (0 = OFF 
and 1 = ON) 
[SENSe:]VOLTage[:DC]:IMPedance:AUTO(?) <n> 
Description  Activates or deactivates (default) the automatic input impedance mode for 
dc voltage measurements. With AUTO OFF, the input impedance is fixed 
at 10 MΩ for all ranges. With AUTO ON, the input impedance is set to 
>10 GΩ for the 100 mV, 1 V, and 10 V ranges. This setting is stored in 
volatile memory.
 
Parameters  <n>  =  OFF or 0  Turns off automatic input impedance. 
      ON or 1  Turns on automatic input impedance. 
 
Examples  VOLT:IMP:AUTO ON  Turns on automatic input impedance. 
Query  VOLT:IMP:AUTO?  Returns the state of the input impedance mode. 
(0 = OFF and 1 = ON)
