4.5.1 Temperature calibration
To calibrate temperature, we recommend a mercury or red spirit
(fluid) thermometer. Bi-metal (dial) and other digital
thermometers are not a good source and have their own margin
of error. Using a local weather station in your area is also a poor
source due to changes in location, timing (airport weather
stations are only updated once per hour) and possible
calibration errors (many official weather stations are not
properly installed and calibrated)
4.5.2 Humidity calibration
To calibrate humidity, you will need an accurate source, such as
a sling psychrometer.
4.6 Logging Mode
The logging mode to be set on the PC software.
There are three types of logging mode: Cycle Mode, Acyclic
Mode, and Segmented Mode.
The default mode is Cycle Mode.

You can set max. 4 time periods through the setting menu on
the PC software. These periods can’t be overlapped. The time
period must be later than the current time. It will start logging
from the set start time and stop from the set end time in a time
period.
Time period icon
