You can switch between the following displays with <M>:
 Conductivity [μS/cm] / [mS/cm]
 Resistivity [Ω·cm] / [kΩ·cm] / [MΩ·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
0.40 ... 1.00. The factor is set in the Measurement menu for the param-
eter, TDS.
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 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.
You can start the Stability control manually at any time, irrespective of
the setting for automatic Stability control (see page 23) in the Measure-
ment menu.
1 Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed.
The HOLD function is active.
