It is possible to set a customize serial number
to Alpha-Log. When Use a substitutive serial
number=YES, this number will be used on the
data file instead of the factory serial number.
It is possible to set the Alpha-Log name and
geographical information. Time zone is needed
to assign the time stamp to the measurements.
Go to Registry-> User and Site information
For more information see §4.1.1.
2.2.2 Setup of the operative mode based on the available energy
Set operating parameters to allow effective management of the available energy. Go to System-> General
settings.
Set the Operative mode:
- Always ON: when main power supply is used.
- Low Power: when power from solar panel is
used.
Set two power thresholds:
- Power threshold high: below this value, Alpha-Log
runs the measurements but stops the data
communication procedure (Run limited).
- Power threshold low: below this value Alpha-Log
stops even the data acquisition procedure (Low
battery). On display the “Power low” information
appears.

2.2.4 Alpha-Log sensors configuration
When one of configuration models suggested by 3DOM is used, remove the sensors not used and/or to add
the ones missed. To add sensors, it is possible to search inside the 3DOM sensors library:
1. In the section Data Logging, select
Measures(1).
2. Press [Add](2).
3. Enter the commercial code (e.g. DMA672.1) and
launch the search (3), or select the code from its
category (4) and press [Ok].
If the sensor hasn’t been found, see chapter
§2.2.4.1.
4. Select Add a new input type (e.g. “DMA672.1: Analog
input”) and press [Add].
5. Set/check that the parameters are appropriate for the
selected type of sensor (e.g. DMA672.1 sensor: Filter
value=50. The quantities measured by the sensor (e.g.
DMA672.1: “RelHumidity”and “AirTemp”) will appear.
6. Double click on the new measurement name and
check parameters in the next labels are correct:
General, Sampling, Elaborations
7. Repeat the operation for the next sensors.
See also §4.1.6.
2.2.4.1 Configuring sensors is not available in the 3DOM sensors library

Alpha-Log can acquire the measurements coming from the ALIEM module connected to its RS-232-Com2(6)
or RS-485-Com3 port(10). Configuration of each ALIEM module must be imported inside the Alpha-Log
configuration. During this procedure the acquisition and elaboration rates are defined for each quantity. Here
the instructions in case ALIEM (model MDMMB1110) is connected to Alpha-Log RS-232 Com2.
This operation should be performed after completing the inputs configuration of ALIEM module (see §3.3).
