Selecting the
displayed
measured parameter
You can switch between the following displays with <M> :

Conductivity [
μ
S/cm] / [mS/cm]

Resistivity [
Ω
·cm] / [k
Ω
·cm] / [M
Ω
·cm]

Salinity SaL [ ]

Total dissolved solids TDS [mg/l] / [g/l]
The factor to calculate the total dissolved solids is set to 1.00 in the fac-
tory. You can adjust this factor to meet your requirements in the range
of 0.40 to 1.00. The factor is set in the menu for the parameter, TDS.
Freezing the measured
value (HOLD function)
With the HOLD function, you can freeze the current measured value.
The displayed measured value stops changing until you switch the
HOLD function off.
Note
If the HOLD function is active, you can, e.g. start a manual measure-
ment with stability control.
Stability control
(AutoRead )
The stability control function (AutoRead) continually checks the stability
of the measurement signal. The stability has a considerable impact on
the reproducibility of measured values. The display of the measured
parameter flashes until a stable measured value is available.
You can start the Stability control function manually at any time, irre-
spective of the setting for automatic Stability control (see section 4.4.3)
in the System menu.
1 Freeze the measured value with <AR> .
The [HOLD] status indicator is displayed.
2 Release the frozen measured value again with <AR> .
The HOLD function is switched off.
The [HOLD] status display disappears.
1 Freeze the measured value with <AR> .
The [HOLD] status indicator is displayed.
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 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. Mea-
surement data meeting the stability control criterion is marked
by AR.
