MEASUREMENT MODE

The

α

lpha TDS 190 controller is capable of taking TDS 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 TDS and Temperature measurement
mode.

Conductivity Measurement Mode
The controller displays the selected TDS range number, R X (X ranges from 1 to
8), for 2 seconds before displaying the TDS measurement. The

ppm

or

ppt

annunciator will light up depending on which range is selected.

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 TDS Measurement mode after
about 30 seconds.
