10.5 Relative measuring

One very useful function is to zero the meas-
ured value at certain locations or points in
time as a reference value from which to ob-
serve subsequent deviations. The offset is
saved temporarily, depending on locking level
(x), to the RAM (5), the base value (4), or the
zero-point (<4). In locking level 6 zero-setting
is disabled.
To set the measured value to zero press
