1-point manual calibration
Performs a manual calibration (Offset adjustment) at a single
reference point.
1
Wait for stable reading
Monitor the process value and
continue (
) to the next step once
the value has stabilized.
2
Enter the new value
Enter the desired PV value by
pressing the
key to move the
cursor and the
keys to
change the value. When the new
value has been entered press the
key to continue.
3
Completion
Following a successful calibration
the calculated coefficients are
displayed.
Following an unsuccessful
calibration the reason for failure
is displayed.
2-point manual calibration
Performs a 2-point calibration using 2 pre-defined buffer
solutions.
