Criteria for a stable
measured value
ba77173e04 12/2017
You can start the Stability control manually at any time, irrespective of the set-
ting for automatic Stability control (see section 11.7.3 A
, page 107) in the System menu.
CONTROL
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 <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.
As soon as a measured value meets the stability criteria, it is frozen. The
[HOLD][AR] status indicator is displayed, 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 <ENTER> at any time. If the Stability control function is
prematurely terminated, the current measurement data are output
to the interfaces USB-B (USB Device, e.g. PC) and USB-A (USB
Host, e.g. USB memory device or USB printer) without AutoRead
info.
3. 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.
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-
