5. ALIBRATION Calibration push button CAL The calibration should be performed after the installation The instrument housing should be grounded Press the CAL button for a few seconds The blue LED will light first then it will be blinking and then the LED will show the colour of the relating operation state as indicating the successful calibration procedure The calibration procedure contribute that after the installation the capacitance change occurring in the tank will be learned by the electronics and considered as initial reference capacitance value If the unit is installed in hazardous Dust Ex environment where the housing cover is not allowed to remove when the unit is energized the calibration can be done without removing the housing cover by a magnet The supplied permanent magnetic screw allows performing the calibration procedure through the aluminium housing 14 CHE op LY fr This case the status LED will blink blue during the calibration All the other configuration settings Sensitivity range selection Sensitivity fine adjustment Delay adjustment Fail safe operation mode selection and switching the Magnetic Calibration switch to ON state should be carried out outside the hazardous environment e g in the control room before mounting the instrument The calibration can be performed multiple times ckm1051a0600h
6. Thank you for choosing a NIVELCO instrument We are sure that you will be satisfied throughout its use 1 APPLICATION The NIVOCAP CK capacitance level switches operate in the RF radio frequency 130 kHz range The instrument is less sensitive to deposits provided by the so called reference probe construction The RF operation principle and the probe construction make the instrument suitable for detecting level of powders and solid materials with relative dielectric constant grather than 1 5 and liquids The device needs to be calibrated after the installation During the operation the electronics continuously evaluates the capacitance difference of the connected measurement probe Until the probe and its close surronding are free in the air the medium to be measured don t reach the probe the minimal capacitance of the measuring and the reference probe is constant Erelative 1 compared to the instrument housing When the medium reaches the probe the basic capacitance will increase Eretative gt 1 The electronic measures this capacitance change compared to an initial capacitance value recorded by the calibration procedure The reference probe construction allows that the material build ups on the probe can be ignored preventing false switching The measurement can be done in four ranges see Chapter 4 Sensitivity range selection 4th sensitivity range 0 5 pF Erelative between 1 5 2 0 3 sensitivity range 2 5 pF relative
