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 mon-
itored 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.
You can terminate the Stability control function and the HOLD func-
tion with <AR> or <M> at any time.
2. Using <MENU/ENTER> , activate the Stability control function manu-
ally.
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 mea-
sured 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. Measurement
data meeting the stability control criterion is marked by AR.
You can prematurely terminate the Stability control function manu-
ally with <MENU/ENTER> at any time. If the Stability control func-
tion is prematurely terminated, the current measurement data are
output to the interface without the AutoRead info.
3. Using <MENU/ENTER> , start a further measurement with stability con-
trol.
or
Release the frozen measured value again with
<AR> or <M> .
The [AR] status display disappears. The display switches back to the
previous indication.
