4.4.2 Measuring
You can carry out conductivity measurements as follows:
Selecting the
displayed
measured variable
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
factory. You can adjust this factor to meet your requirements in the
range of 0.40 to 1.00. The factor can be set in the TDS measuring
menu.
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
measurement with stability control.
1 Perform the preparatory activities according to section 4.4.1.
2 Immerse the conductivity measuring cell in the test sample.
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.
