6.6 B-A
– Relative Deviation
Measuring function B-A can be used to determine deviation. The value obtained from the reference part
is usually used as reference value A. Reference value A can be frozen by pressing the HOLD key. After
briefly pressing the assigned function key, the B-A measuring function is activated and the measured
or frozen measured value is saved as reference value A. The momentary measured value then appears
at the upper display and relative deviation appears at the lower display. The momentary measured
value pair is saved by pressing the MEM key and the number of measured values is increased at the
display. The B-A measuring function is terminated by briefly pressing the assigned function key and a
prompt is displayed asking whether the function values should be saved or discarded.
