sure and input the salinity of the measured medium first.
When the salinity correction is switched on, the [Sal] indicator is displayed in
the measuring screen.
Air pressure correction The air pressure is automatically used for air pres-
sure correction during calibrating and for the display of the oxygen saturation
[%] parameter.
You can view the current air pressure in the sensor menu when an IDS D.O.
sensor is connected. In the measured value display, press the <ENTER> key.
The current air pressure is displayed as a piece of information.
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 11.7.3
A
UTOMATIC STABILITY CONTROL, page 107) in the System menu, you can start a
measurement with Stability control manually at any time.
You can switch the salinity correction on or off and enter the salinity
in the menu for calibration and measurement settings (see section
11.4.1 S
ETTINGS FOR D.O. MEASUREMENT, page 101).
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.
