Humidity - CalibrationModules for measuring relative air humidityOur humidity data loggers are supplied with a precisely calibrated humidity sensor. It is recommended thathumidity sensors used in normal environments are checked every 6 - 12 months and recalibrated ifnecessary. In particularly contaminating environments, it may be necessary to clean the sensor verycarefully using water or a max. 40% alcohol solution.Method of humidity verification:Using our SCS calibrated calibration solutions forthe operating points with relative humidity valuesof 0%, 10 %, 20%, 35%. 50%, 65%, 80% and90%.Verification is more important than calibration!Making use of the calibration solutions, it ispossible to simulate a variety of humidity levels atthe sensors. The module should then beevaluated and the results checked. There is noreal point in carrying out recalibration unless adeviation of more than ±2% is determined.RecalibrationThe PC software provides support for automaticrecalibration of the modules. The followingequipment and materials are required:- a calibration unit- calibration solutions for 0% .. 95%- a calibration box or thermally insulated box- evaluation software elproLOG WIN- a PC interface (only for Hamster andHOTDOG)Recalibration of the modules is carried out byselecting “Extended Setup” from the programmenu. For most applications, calibration with the80% solution will be suitable. After the procedureis started, an automatic program runs in themodule for a period of 3 hours, after whichcalibration is complete. The logger status shows,if the calibration has been successful or not.sensor part of the module. The sealing ring can thenbe pulled on.The actual calibration process begins automaticallyafter 2.5 hours. It is necessary to keep the ambienttemperature constant during calibration. The module,with calibration unit fitted, must therefore be kept inan insulated box for a period of at least 3 hours afterthe start of the process. It can be evaluated at theend of this time. The module’s temperature and timeranges can, if necessary, be reprogrammed before itis put back into use.Clean well and dry in acurrent of airSelect a short timeinterval.Start “calibration”only if you wish torecalibrate.Empty calibration solution overfabric discClose the unit, push onto sensorand pull on sealing ringLeave in insulated containerthen evaluateIMPORTANT:The calibration unit must be absolutely clean anddry before it is used. The unit should, therefore,be disassembled, washed and then driedthoroughly in a current of air. The fabric discsupplied (except for 0%) is then inserted in thebaseplate of the unit. The ampoule containing thecalibration solution is broken open and the liquidpoured over the fabric disc. The unit, with thebaseplate underneath, is then pushed onto theIMPORTANT:Humidity probe and module are forming a pair.Calibration values must be entered before the first use.D-DZ-6001E9.1999
