The minimum duration until a measured value is assessed as stable is the
monitored time interval. The actual duration is mostly longer.
Manually starting
the stability control
You can start the Stability control manually at any time, irrespective of the set-
ting for automatic Stability control (see section 7.1.1 C
, page 38) in the Measurement menu.
Freezing the mea-
sured value (HOLD
function)
With the HOLD function, you can freeze the current measured value. The dis-
played measured value stops changing until you switch the HOLD function off.

1.
Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed.
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. 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 interface without the AutoRead info.
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.
If the HOLD function is active, you can, e.g. start a manual mea-
surement with stability control.
1.
Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed.
