Page 20: Function Check
® Measuring / Operation 70x IQ (SW) 2 cm With air temperatures under 5 °C we recommend performing the function check and user calibration not in air but in air-saturated water that has a higher temperature. You obtain air-saturated water by pouring water several times in and out of two vessels so that it sparkles. - Page 21 ® 70x IQ (SW) Measuring / Operation Press The sensor starts the check. The display switches to the mea- sured value display. The CAL indicator flashes instead of the main measured value. At the same time, the momentary rela- tive slope flashes as the secondary measured value with the addition of TEST.

Page 22: User Calibration
® Measuring / Operation 70x IQ (SW) 4.2.3 User calibration Principle The user calibration can either be done in water vapor-saturated air or in air-saturated water (see C HECK OR CALIBRATION MEDIUM page 4-1). With the calibration procedure, the relative slope of the sen- sor is determined. - Page 23 ® 70x IQ (SW) Measuring / Operation Wait for the measured value to be largely stable (temperature adjustment).
