Note: During each log interval, the HygroLog is active for only the few seconds required to
measure and record the data. The rest of the time, the HygroLog is in a "sleep mode". In this
mode, humidity and temperature conditions, including alarm conditions, as well as events such as
removal of the probe are neither detected nor recorded.

Memory

The HygroLog can record a maximum of 5,450 data samples. Each data sample includes
the following information: humidity, temperature, date and time.
Events such as the removal of the HygroClip probe, the replacement of batteries, etc.,
are also recorded. Limit the number of such events so as to maximize the amount of memory
available for recording actual data.

Display (HygroLog D)

Description of the Display Functions:
Humidity 0 to 100 %RH or %HR
Temperature -50.0 to 199.9°C or °F (Fahrenheit temperature values above 200 are
displayed without decimal)
Operation Immediately after programming, the LC display does not show the
measured values during the first two measuring cycles. After this initial
phase, the display is updated
during each log interval.
Alarm Indication Alarm conditions are indicated by one or more triangles at the bottom of the
display. Several alarm conditions may be displayed simultaneously. An
upward pointing triangle indicates that the maximum alarm value was
reached or exceeded. A downward pointing triangle indicates that the
minimum alarm value was reached or exceeded. Inside the triangle, the
letter H or the letter T denotes humidity or temperature.
The alarm indication remains on the display even after conditions have
returned to normal. The alarm indication can be turned off only with the
HW3 software.
