10. :SOURce:CLOop#:RACTion OFF - Set the control loop ramping off (where # is the control
loop instance)
- Example :SOURCE:CLOOP3:RACTION OFF – set ramping off for control loop 3
11. :SOURce:CLOop#:RACTion STArtup - Set the control loop to ramp the set point when the
controller powers on(where # is the control loop instance)
- Example :SOURCE:CLOOP4:RACTION STARTUP – set ramping on at start up for control
loop 4
12. :SOURce:CLOop#:RACTion SETPoint - Set the control loop to ramp the set point when the
set point is changed (where # is the control loop instance)
- Example :SOURCE:CLOOP3:RACTION SETPOINT – set ramping on when the set point is
changed for control loop 3
13. :SOURce:CLOop#:RACTion BOTH - Set the control loop to ramp the set point both when
the controller is powered on and when the set point is changed (where # is the control
loop instance)
- Example :SOURCE:CLOOP2:RACTION BOTH – set ramping on at start up and when set
point is changed for control loop 2

26. :UNIT:TEMPerature:DISPlay C Set displayed temperature units to C
27. :UNIT:TEMPerature:DISPlay F Set displayed temperature units to F
28. :OUTPut#:STATe? - Query the state of an event output where # is the output number (1-8)
- Example :OUTPUT1:STATE? – query the state of event output 1
29. :OUTPut#:STATe OFF - Set the event output off where # is the output number (1-8)
- Example :OUTPUT2:STATE OFF – set event output 2 off
30. :OUTPut#:STATe ON - Set the event output on where # is the output number (1-8)
- Example :OUTPUT3:STATE ON – set event output 3 on
