Step 2: Set the conductivity in the same manner as the wet calibration procedure. Step 3: Connect a different value resistor to the "Drive" and “Ground" terminals, and verify the linearity. If the transmitter displays an incorrect value (±2% of reading), contact Sensorex technical support. Parts per Million (PPM) Factor When the unit in the calibration menu is PPM, the following information is useful. -
