7.2.6 Difficulty Calibrating Permeate Conductivity
The integrity of the permeate conductivity circuitry on the main logic
board can be verified by connecting a fixed resistor in place of the
conductivity probe.
1. Turn the machine OFF.
2. Unplug the power cord for the ECM-100.
3. Disconnect the permeate conductivity wires from terminal
posts 27 and 28.
4. Install a 5 or 10 K ohm resistor between terminal posts 27 and
28.
5. The resulting conductivity should be displayed on the ECM-
100.
• 10 K ohm should give a reading of 10 S.
• 5 K ohm should give a reading of 20 S.
6. If the ECM-100 does not display the correct permeate
conductivity then the main board may need to be replaced.
