1620A “DewK” Thermo-Hygrometer Getting Started Guide Replace the battery cover. Replace the DC power cord and switch the power on. Used batteries must be disposed of properly. See the WARNINGS section at the beginning of this guide. Sensor Configuration The thermo-hygrometer can be used with one or two sensors of either type attached at either of the two ports. -
Page 23: Measuring
5 General Operation Measuring The thermo-hygrometer will automatically make measurements on enabled channels at the set period when a sensor is attached. Channels are enabled using the CHANNEL SETTING func- tion in the CHANNEL menu. The measurement period is also set with this function. Unit of Temperature The thermo-hygrometer is capable of displaying temperature in Celsius (C) or Fahrenheit (F). - Page 24 1620A “DewK” Thermo-Hygrometer Getting Started Guide First, consider that the sensor actually measures its own temperature, not necessarily the tem- perature of the air around it. Ideally, the sensor’s temperature will be the same as the air, but they might be different under less than ideal conditions. One such condition is when there is a source of radiated heat that is “seen”...
