Tag Calibration
Before you begin the calibration process, it is important
to know the following information:
 You must have already specified the tag number
you want to calibrate on the Tag Status screen in
the Main level. (In other words, you cannot specify
a tag number from the Execute screen.)
 You can cancel the calibration test at any time
during the process by pressing the CLR key to
return to the Tag Status screen.
To perform tag calibration, do the following:
1. Access the Execute screen for the particular tag
you want to calibrate. The BetaGauge II prompts
you to apply the first test point measurement input.
2. Apply the required field instrument input value for
the current test point.
NOTE: The BetaGauge uses the measured field
instrument input to calculate the ideal field
instrument output. It can then determine whether
the measured field instrument output is within the
allowed error tolerance specified in the tag. Keep
in mind, however, that if you accept an input value
that is one percent low, the BetaGauge II will
expect the ideal field instrument output to be one
percent low as well.
