5 seconds The ROTRONIC HW4 software is required to view the measured or calculated data on a PC monitor. Connect the data logger to the HW4 PC as explained under “Initial Start-up”. HW4 is also required to download and save the recorded data to disk. -
Page 16: Practical Advice For Measuring Temperature And Humidity
Non-moving air is an excellent insulator. When there is no air movement, surprising differences in temperature and humidity can noted over short distances. Air movement at the probe generally results in measurements that are both faster and more accurate. © 2015; Rotronic AG IN-E-HL20-V1_16 GlobalTestSupply www. -
Page 17: Maintenance
Long term stability of the ROTRONIC Hygromer humidity sensor is typically better than 1 %RH per year. For maximum accuracy, calibration of the HL20 should be verified every 6 to 12 months. -
