Tolerance:
A means ratio between 0.995 and 1.005 inclusive is considered equal to a ratio of 1.000, and
no adjustments to the Relative gain is necessary. In this case the “Tolerance” field will be
green and state “No”.
If the means ratio is greater than ±0.005 the “Tolerance” field will be red and state “YES”.
The Relative Gain will then have to be updated in DDC (see next section “Deflector gain
adjustment”) and the Relative calibration should be performed again
2% Range:
The means ratio must be within the range of 0.980 and 1.020. Contact Dynatest for evaluation
of the deflection sensor if it is out of the 2% range.
13.1.3 Gain Adjustment
As described in previous section a means ratio greater than ±0.005 requires an update of the
relative gain for the deflection sensor.
In DDC go to [Setup] [deflectors].
Update the values in “Rel. Gain” column to reflect the ones in the “New Relative Gain”
column in the “PrEN-5 RelCal.xlsx”. The Relative calibration should now be performed
again, to ensure that the new relative gain is correct, and means ratio are within tolerance.
The relative calibration is now completed.
If you want to save the result in “PrEN-5 RelCal.xlsx” remember to choose the “Save as”
option and leave the original worksheet for the next relative calibration.
