Page 2: Positioning The Instrument
User manual Positioning the instrument Insert the sword-sensor into the stack for only approx. 10 cm, and push it a few more centimetres into the stack every 10 seconds. Let your humimeter RH5 adequately adjust to the material (at least five minutes) before you start to measure, particularly when the material pile was stored at a different temperature than the device. -

Description of definitions Relative air humidity: indicates the relation between the current water vapour pressure and the maximal possible water vapour pressure (called saturation vapour pressure) The relative humidity shows the degree the air is saturated with water vapour. For example: 50% relative humidity indicates that at the current temperature and the current pressure the air is saturated with water vapour for half of its value, 100% relative humidity means that the air is totally saturated. -

Operating the instrument Switching on: Press for three seconds. Changing the calibration curve: Setting date and time: 2 times - Options – date / time Set date and time using the button , according to the format indicated (JJ.MM.TT). After entering the year, press the button for entering the month and again for entering the day. - Page 7 Proceedings Preparation To ensure as good as possible inspection results it is essential that the measuring device, the calibration equipment and the calibration ampoules have approximately the same temperature. This temperature has to be between 20° C and 26° C. The best way to ensure the same temperature of the different components is to store all components together in a room with only small temperature fluctuations minimum over night –...
