Note
You can prematurely terminate the Stability control function manually
with <MENU/ENTER> at any time. If the Stability control function is pre-
maturely terminated, the current measurement data are output to the
interface without the AutoRead info.
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.
2 Using <MENU/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. The progress bar disappears
and the display of the measured parameter stops flashing.
The current measurement data is output to the interface. Mea-
surement data meeting the stability control criterion is marked
by AR.
3 Using <MENU/ENTER>, start a further measurement with Sta-
bility control.
or
Release the frozen measured value again with <AR>.
The display switches to the measured value display.
The [AR][HOLD] status display disappears.
