WHAT HAPPENS WITH DIFFERENT TYPES OF LIMIT?
In the example shown above, percentage limits were chosen before clicking on the
Measure button. In this case, the measured result from the tester is inserted as the
nominal value, allowing you to set the limits for the test as a percentage either side of
this nominal value.
If you choose one of the other possible limit types before clicking on the Measure
button, the following table shows the way in which the measured result will be
converted to edit box values:
Limit Type Conversion
% nom ← result
|neg%| ← no change
pos% ← no change
dB nom dB ← result
|neg dB| ← no change
pos dB ← no change
> < min ← result - 0.01%
max ← result + 0.01%
> low ← result
< upp ← result
%
for TR
or TRL
pri ← result
sec ← 1
|neg%| ← no change
pos% ← no change
#
for TR
or TRL
#np ← result * K
#ns ← K
← no change
← no change
Where, as before:
nom = the nominal value for the [ % ] limits
neg% (pos%) = the negative (positive) percentage error for the
[ % ] limits
min (max) = the minimum (maximum) value for the [ > < ]
limits
low = the minimum value for the [ > ] limit
upp = the maximum value for the [ < ] limit
pri, (sec) = the primary (secondary) ratio number for the [ % ]
limits - TR or TRL test
And for the TR or TRL test:
neg% (pos%) = the negative (positive) percentage error for the
[ % ] limits
#np (#ns) = the number of primary (secondary) turns for the
[ # ] limits
