1. Take a sample of the permeate from the permeate sample port
[about 8 ounces (0.24 L)] in order to establish the known
conductivity.
2. Measure the permeate conductivity reading from the sample
collected.
Be sure to rinse the conductivity meter thoroughly in a stream of
water from the permeate sample valve before taking the reading.
3. Locate the potentiometer marked “perm” on the main circuit
board.
The main circuit board is in the door of the enclosure.
The potentiometer marked “perm” is in the center on the right-hand
side of the circuit board.
4. While the machine is running, adjust the potentiometer marked
“perm” until the ECM-100 permeate conductivity reading
matches the conductivity as measured by the hand-held meter
[at 77F (25C) for some meters] while the machine is running.
• Counterclockwise (CCW) increases the conductivity
reading.
• Clockwise (CW) decreases the conductivity reading.
5. Saving to Factory Settings (Menu 11).
NOTE:
Whenever a value is adjusted it must be saved in the Factory Settings
Menu (11).
• Press ESC twice to return to the ECM-100 default menu.
• Press the ARROW keys to scroll to the Maintenance Menu
(07).
• Press ENTER to select the Maintenance Menu.
• In the Maintenance Menu, use the ARROW keys to scroll to
the Factory Settings Menu (11).
• Press ENTER to select Factory Settings.
