    Where a convenient installation is not possible using the standard cables between sensors and transmit- ter, a junction box and extension cable may be used. The Yokogawa BA10 junction box and the WF10 extension cable should be used. These items are manufactured to a very high standard and are neces- sary to ensure that the specifications of the system are not compromised.

  • Page 51: Temperature Compensation

    Parameter setting 5-9 5-2-3. Temperature compensation Why temperature compensation? The conductivity of a solution is very dependent on temperature. Typically for every 1 °C change in temperature the solution conductivity will change by approximately 2 %. The effect of temperature varies from one solution to another and is determined by several factors like solution composition, concentra- tion and temperature range.

    (we recommend Yokogawa's Personal Conductivity Meter). The reference tempera- ture of both meters should be the same, and as far as possible you should perform the calibration at the reference temperature, as there will otherwise be temperature compensation errors if the temperature compensation functions of the two meters are not exactly the same.

    Appendix 2-7 12-4-2. Commissioning Mode Settings 12-4-2-1 Output Range Setting Refer to Sec. 5-2-1 1. What does output range setting involve? When linear output (linear relationship between conductivity and analog output) is selected, the meas- urement range corresponding to the 4 to 20 mA DC analog output range must be set. The default measurement range is 0 to 1,000 mS/cm.

When washing finish- es, and a new batch starts, HOLD is turned OFF again and the sensor reverts to conductivity measure- ment. 4. Auto Return If AutoReturn functions are enabled, the instrument reverts to measurement mode after a preset time (10 min.
