Stability control
(AutoRead)
& HOLD function
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility 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.
Irrespective of the setting for automatic Stability control (see section 9.5.3
A
UTOMATIC
S
TABILITY CONTROL
, page 69) in the System menu, you can start a
measurement with Stability control manually at any time.
The DO % Saturation local function for the parameter oxygen sat-
uration [%] is switched on or off in the menu for calibration and
measurement settings (see section 9.3.1 S
ETTINGS FOR D.O. SEN -
SORS ( MENU FOR MEASUREMENT AND CALIBRATION SETTINGS ), page
63).
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 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 mea-
sured 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 <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.
