To protect the device from static electrical discharge, the user must be electrostatically discharged before touching the instrument!

  • Page 10: Connecting The Sensor

    5.1 Connecting the sensor To connect the pH redox electrode, special coaxial lines are recommended as specified by JUMO datasheet 202990. Standard commercial antenna or computer lines with coaxial construction are generally not suitable. They may result in faulty readings or could destroy the pH or redox electrode.

    5.2 Customizing the special coaxial line Example: ~40 mm Strip insulation from the line as shown in the drawing. Remove the black semiconducting layer (2) from the insulation of the inner conductor as indicated. Twist the shield (1) and insulate with a shrink tubing. Insulate the black semiconducting layer with shrink tubing (2) to prevent short circuits.

  • Page 18: Operation

    7.2 Operation The instrument can be operated on different levels. Access to all levels (except the user level) is protected by different codes On the User level (USER) all parameters can be viewed and/or modified depending on user rights (see Enable level). On the Calibration level (CALIB) the electrode zero point (intercept point) and/or the electrode slope can be calibrated.

  • Page 25: Configurable Parameters

    8 Configurable parameters Parameters can be set with the setup program or on the instrument. Since some parameters are independent of each other, it may be necessary when one parameter is changed to adjust others as well. Example: When the measurement variable is changed (from pH to redox voltage or vice versa) the display format, setpoints, and other parameters are adjusted.

  • Page 40: Calibration

    9 Calibration 9.1 General information The zero point (intercept) and slope of pH sensors stray from copy to copy. During the service life of the sensor, up to the time it must be replaced by a new sensor, the zero point and slope change. To allow for precise measurements, the transmitter must be adjusted (calibrated) to the current sensor parameters.

  • Page 41: Starting Calibration From The Calibration Level "Calib

    Calibration can be cancelled at any time with the EXIT key. Old calibration data will not be lost. Calibration is performed using the instrument keys. The zero point and slope of a sensor can also be entered manually. This should only be done in exceptional cases.

  • Page 42: Canceling Calibration And Error Messages

    9.3 Canceling calibration and error messages Calibration can be cancelled at any time with the EXIT key. Old calibration data will not be lost. During the calibration process, the transmitter calculates the electrode parameters zero point and if applicable slope. If the calculated values fall outside the permissible parameter limits, an error message is generated.

  • Page 43: Acknowledging Errors

    The parameter limits for NULL and SLOPE have been violated and/ or the two calibration points Ref.1 and Ref.2 are too close to each other. For two-point calibration of a pH sensor, the minimum spacing is 2 pH. For two-point calibration of a redox sensor, the minimum spacing is 2 mV.
