4.7.4 Measurement board
The different measurement boards for the EC and TC sensors are illustrated in
Figure 7. The type of board is easily identified by the color of the J8 connector. For EC boards this
connector is colored orange, and for TC boards it is colored black.
It is extremely important that sensors are connected to the correct measurement board. Connecting
a TC sensor to an EC measurement board (and vice versa) will cause irreparable damage to the
measurement board.
