Data sheet
Place your hygrometer in the room where you want to measure the humidity level. Please observe the following guidelines:
All hygrometers have a margin of error of +/- 5%. To compare two displays, the measurement must be carried out under the same conditions (e.g. same temperature) and in the same location.
The battery may be inserted incorrectly. Make sure to slide it under the 2 metal tabs, otherwise there will be a bad contact.
Take a paper clip and press the ON/OFF button underneath the device to display/deactivate the clock.
The clock settings are saved after 5 seconds without input.
