Full Memory
Measurement is stopped when the memory is full (32 000 values)
Wrap around
Readings never stop, The oldest records are replaced with newest ones as the
number of readings exceeds the memory capacity.
After
The logger stops readings after a number of readings defined in the corresponding
edit field
Date
Readings stop at user-predefined date and time. In case the logger memory
capacity is reached before the date defined, readings are also stopped
Channels
Register Card with parameters related to temperature measurement. There are two
separate Channels: Channel 1 for Temperature and Channel 2 for Humidity
Unit
Defines the unit of the Temperature (channel 1) value measured: ºC or ºF and %
RH only for the humidity (channel 2)
Value
Defines how the value measured will be registered. 3 Options are available:
Instantaneous
The logger measures the temperature once at the end of the predefined
measurement interval (Period) and save the measured value in the internal
memory. The minimum interval between measurements is 1 seconds.
Average
The Logger takes 10 equidistant measurements within the predefined
measurement interval (Period), build the average of these ten values and store the
result in the internal memory. The minimum interval between measurements is 10
seconds.
Maximum
The Logger takes 10 equidistant measurements within the predefined
measurement interval (Period) and stores the highest value of them in the internal
memory. The minimum interval between measurements is 10 seconds.
Minimum
The Logger takes 10 equidistant measurements within the predefined
measurement interval (Period), and stores the lowest value of them in the internal
memory. The minimum interval between measurements is 10 seconds.
Offset
Gives the user the possibility to automatically correct the value logged.
Alarm
Defines limit values that, when exceeded (high) or undershot (low), characterize an
alarm condition. Alarm events are informed to the user through a flashing mode of
the Alarm Indicator.
Input
Parameter only available in Channel 2 (humidity). It allows disabling of humidity
measurements, hence, saving all memory capacity for temperature measurements.
After filling all the fields select OK and settings will be sent to the logger
Note: After clicking the OK button all previous settings and previous data logged are lost.
