To calibrate the thermohygrometer, use a temperature/humidity generating chamber to
produce reference temperature and reference humidity. A chamber capable of achieving a
temperature repeatability within ±0.1°C, humidity repeatability within ±1.0%, and humidity
variability between 0 and 90% is required.

- Page 2 Temperature calibration The upper figure of the LCD indicates temperature and the lower figure indicates humidity. The value is decreased by turning the respective volume control counterclockwise and increased by turning it clockwise. (1) Leave at 23°C, 0%, for 30 minutes. (2) Use a flat head screwdriver to adjust VR1 to 23.0°C.
