Preface This manual serves to explain the use of the lpha CON 2000 Series. The manual functions in two ways, firstly as a step by step guide to help the user operate the instrument, and secondly as a handy reference guide. This instruction manual is written to cover as many anticipated applications of the lpha CON 2000 as possible. If you have any doubts concerning the use of the instrument, please do not hesitate to contact the nearest Eutech Instruments Authorised Distributor. [. . . ] The transmitter returns to the Measurement mode and the old calibration values remain active. The calibration security code automatically resets from "11" to "000" after the transmitter returns to Measurement mode.

1. The display momentarily shows the cell type ("2 CELL" or "4 CELL") to which the transmitter is configured before displaying the last set cell constant (k) Important: If set for a 2 cell operation, make sure that the outer and inner electrode points are shorted on the connector (pins 15 and 16 shorted and pins 17 and 18 shorted). Immerse the sensor in a suitable standard solution, whose value is within the measurement range selected in the transmitter. Note: The calibration standard must have a value that is 10% to 100% of full scale of the range selected. For example, if the range in the controller is selected to be 2000 µS (range 4), then the calibration standard value should be 200 µS to 2000 µS. The display then shows the current measured value of the calibration standard solution. Once the reading stabilises press the or key to adjust the measured value to that of the standard solution. Note: The acceptable calibration window is ±40% of the displayed (default) value. If the display is 1000 µS, the values to which it can be adjusted is 600 to 1400 µS. If there is a calibration error the transmitter displays "ERR" and return to the measurement mode. This serves as a diagnostic feature to indicate the effectiveness of the electrode which will degrade with time and usage. An effective electrode should be within the calibration factor window of 0. 60 to 1. 40. Press the ENT key to return to the Measurement mode.

Note: If you entered the Calibration mode from the Setup mode, the transmitter will return to the setup menu. Note: When calibrating with manual temperature compensation, the transmitter automatically changes from the preset process temperature to the calibration temperature. After leaving the Calibration mode, the transmitter switches back to the process temperature (for setting the calibration temperature and the process temperature, see section 6. 3).
