26 MAINTENANCE HygroSmart HS3 User s Manual 6.2 Probe Adjustment Procedure The probe electronics provide a functionality which allows the user to apply a 5 point correction table to the reading received from the sensor module, and adjust the probe accordingly. The usage of the adjustment tool in the application software is covered in Section 3.6. This section specifically relates to the method of generating the known conditions required to make accurate adjustments. In order to make a valid adjustment, the probe should be exposed to a environment of stable humidity and temperature, which is also measured by an authoritative traceable reference instrument. Michell Instruments offers a number of devices suitable for the purpose, either with or without temperature control. HygroCal100 The HygroCal100 enables quick and convenient generation of a known humidity condition at ambient temperatures. Its chamber allows seven relative humidity probes of various diameters to be installed into the chamber simultaneously. The probes can be powered directly from the HygroCal100, and monitored via the intuitive touch screen user interface. This interface also allows the programming of a calibration profile, so that a series of humidity values can be generated and held automatically for a set time period. The readings from all probes under test and the built-in reference can also be logged for completely autonomous operation. The system is entirely self-contained, and weighs just 3.2kg (7lbs) (including the battery pack), so is easily portable for making multiple on-site checks. OptiCal For calibration at a variety of temperatures, the OptiCal humidity calibrator provides a stable and accurate calibration environment over the 10 to 90% RH and +10 to +50 C (+50 to +122 F) range. The stand-alone, transportable calibrator requires no external services other than mains power, and features an integrated chilled mirror reference instrument to enable the operator to perform calibrations that are traceable to national standards Issue 1, February 2016
