Relative measuring
One very useful function is to zero the meas-
ured value at certain locations or at certain
times as a reference value in order then to ob-
serve only the subsequent deviations. This
function is independent of the locking status
and does not modify the programming parame-
ters in the connector.
To zero-set the measured value press key :
CLR
.
To display relative measuring press arrow :
REL
.
To return to normal measured value press and hold down key :
CLR
.
Setting to zero automatically deletes the maximum and minimum val-
ues for this channel. The
MAX
,
MIN
, and
MEM
functions are thus also
available for relative measurement.
