Continue
Ensure that a span solution is
present at the sensor, monitor the
process value and continue ( ) to
the next step once the value has
stabilized.
2 Enter the new value

Continue
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 Sampling
The procedure moves automatically
to the next stage once the PV has
been sampled.
4 Completion
Following a successful calibration
the calculated coefficients are
displayed.
Following an unsuccessful
calibration the reason for failure
is displayed.
