4 MEASUREMENT MODE
The α lpha CON 190 controller is capable of taking conductivity measurement with
Automatic (ATC) or Manual (MTC) Temperature Compensation.
The measurements are displayed distinguishingly by the annunciators on the front
panel.
4.1 Measurement mode display
Press the MODE key to toggle between Conductivity and Temperature
measurement mode.
Conductivity Measurement Mode
The controller displays the selected Conductivity range number, R X (X ranges
from 1 to 8), for 2 seconds before displaying the Conductivity measurement. The
µS or mS annunciator will light up depending on which range is selected.
Conductivity Range Range No., R Resolution Cell Constant
0.00 – 20.00 µS/cm 1 0.01 µS/cm 0.1
0.0 – 200.0 µS/cm 2 0.1 µS/cm 0.1
0.0 – 200.0 µS/cm 3 0.1 µS/cm 1
0 – 2000 µS/cm 4 1 µS/cm 1
0.00 – 10.00 mS/cm 5 0.01 mS/cm 1
0.00 – 20.00 mS/cm 6 0.01 mS/cm 1
0.0 – 200.0 mS/cm 7 0.1 mS/cm 1
0.0 – 200.0 mS/cm 8 0.1 mS/cm 10
Temperature Measurement mode
Press MODE key once to view the temperature measurement. The °C annunciator
lights up. The display shows ATC or MTC, then the current measured temperature.
For selection of temperature compensation ATC or MTC, see Setup program P4.1.
NOTE: After pressing the MODE key to display Temperature, if there is no further
key-press, the Controller will automatically revert to Conductivity Measurement
mode after about 30 seconds.
