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 10.6.3
A
, page 97) in the System menu, you can start a
measurement with Stability control manually at any time.
Criteria for a stable
measured value
The Stability control function checks whether the measured values are stable
The Saturation local function for the parameter oxygen saturation
[%] is switched on or off in the menu for calibration and measure-
ment settings (see section 10.4.3 S
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. When the Stability control function
is prematurely terminated, the current measurement data are out-
put to the interface (PC, USB memory device or USB printer) with-
out 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.
