( [POS SET T SLOPE CAL] )
!000.0002F
( [POS SET T OFFSET CAL] in Volts)
Calibrating Negative SET T Slope & Offset
•
These commands calibrate the negative voltage SET T setpoints.
Write

!000.0002D
( [NEG SET T OFFSET CAL] in Volts)
Reading the Current Calibration Settings
•
To read the current calibration settings, the Command Type changes from a
WRITE (2) to a READ (1) and no [PASSWORD] is required.
