Criteria for a stable
measured value
The
Stability control
function checks whether the measured values are
stable within the monitored time interval.
The minimum duration until a measured value is assessed as stable is
the monitored time interval. The actual duration is mostly longer.

Measuring the ORP
Note
ORP electrodes are not calibrated. However, you can check ORP elec-
trodes using a test solution.
Note
You can prematurely terminate the
Stability control
function manually
with
<ENTER>
at any time. If the
Stability control
function is prema-
turely terminated, the current measurement data are output to the
interface without the AutoRead info.

Using
<ENTER>
, start a further measurement with stability
control.
or
Release the frozen measured value again with
<AR>
or
<M>
.
The [AR] status display disappears. The display switches back
to the previous indication.
