5 CONDUCTIVITY CALIBRATION IMPORTANT: When Calibration mode is entered, controller automatically goes into a “HOLD” mode where the 4-20 mA output freezes and relays are de-activated (if it was in an activated condition). Upon return to measurement mode, both 4-20mA output and relay activities resume, depending on settings. - Page 16 50 9 50 0 ENTER d o n e ENTER Notes: You can view the calibrated Conductivity value from Setup program. See Setup program P5.0. Controller displays calibrated conductivity point for selected range. If calibration is not done for the selected range, controller displays ‘- - - -‘. If after thorough cleaning of electrode and ERR1 is displayed after an attempted calibration, consider changing electrode.
