Stability control
(AutoRead )
The stability control function (AutoRead) continually checks the stability
of the measurement signal. The stability has a considerable impact on
the reproducibility of measured values.
The measured parameter flashes on the display
 as soon as the measured value is outside the stability range
 when the automatic Stability control is switched off.
You can start the Stability control manually at any time, irrespective of
the setting for automatic Stability control (see page 26) in the
Measurement menu.
Note
You can prematurely terminate the Stability control function manually
with <ENTER> at any time.
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.
1 Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed.
The HOLD function is active.
2 Using <ENTER>, activate the Stability control function
manually.
The [AR] status indicator appears while the measured value is
assessed as not stable. A progress bar is displayed and the
display of the measured parameter flashes.
The [HOLD][AR] status indicator appears as soon as a stable
measured value is recognized.
3 Using <ENTER>, start a further measurement with Stability
control.
or
Release the frozen measured value again with <AR>.
The display switches to the measured value display.
The [AR][HOLD] status display disappears.
