25DVD-240On customer request, probe for air temperature and relative humidity measurement is delivered.In that case, additional connector for connection of this probe (USB type) is installed on moisture meter .Air temperature and relative humidity measurement using portable moisture meter and probe for airtemperature and relative humidity is very simple and quick. It is only required to connect the probe touniversal portable moisture meter via special USB type connector, turn the meter on and press the buttonDSVT-03DVD-2409.1 Air temperature and relative humidity measurement procedureDVD-240DSVT-03DVD-240to read current air temperature ( ), i.e., press the button to read current air humidity ( ).It is required to wait at least 1 minute before initial measurement in order to allow the sensor inside the probe toadopt to ambient conditions (if it was previously stored on significantly different temperature or humidity). Also,for more accurate measurement, if hole measurement set is taken from cold into warm room, it should be leftfor short time (several minutes) to adopt, and then proceed with measurement.During temperature and humidity measurement inside the dryer, probe body should be placed inside thechamber, while part of cable with connector and portable meter is held outside of it. This is precautionmeasure to avoid damaging the meter if operating conditions are exceeded. Measurement should beperformed after sensor is adopted to ambient conditions inside the chamber (few minutes).in C in %o
