Performing Auto Sensor Calibration and Zero Adjustment
6. Performing Auto Sensor Calibration and Zero 
Adjustment
You can use the procedures in this section to perform auto sensor calibration and sensor 
zero adjustment. 
With auto calibration, you can configure applicable interpolation formula slope (Slope) and 
y-intercept (Intercept) values for a sensor based on two measured values.
With zero adjustment, you can configure a custom probe 
y-intercept based on measured 
values.
A sensor calibrated with auto calibration or zero adjustment is registered as a custom probe.
Sensor Calibration Screen
1. On the sampling screen, use f and c to move the highlighting to the sensor you want 
to auto calibrate or zero adjust.
2. Press 3(CALIB).
This displays a sensor calibration screen like the one shown below.
1(EDIT) ... Select to manually modify the highlighted item.
2(CALIB) … Performs auto sensor calibration.
3(ZERO) … Performs sensor zero adjustment.
6(SET) … Select to assign the calibrated sensor to a channel. This registers the 
sensor as a custom probe.
Press J to return to the sampling screen.
Performing Auto Sensor Calibration
Important!
Before performing the operation below, you will need to have two known measured values 
on hand.
When inputting reference values in step 3 of the procedure below, input values that were 
measured accurately under conditions used for the sampling operations in step 2 of the 
procedure. When inputting reference values in step 5 of the procedure below, input values 
that were measured accurately under conditions used for the sampling operations in step 4 
of the procedure.
