5.13 Differential value display
The differential value display shows the difference be-
tween a nominal value setting and the measured thick-
ness value. The difference is displayed as an absolute 
value and as a percentage of nominal value. 
A differential value with a positive sign means that the 
measured value is above the nominal value, a negative 
sign means that the measured value is below the nomi
-
nal value. With a nominal wall thickness of 7.00 mm, for 
example, the value 6.27
 mm is displayed as -0.73 mm 
and -10.43%.
