M-Log additional features
M-Log is an instrument designed to acquire, elaborate and store measures from sensors connected
to its analogue, digital and serial inputs. On the base of the acquired data it can operate field
actuations according to the programmable algorithms.
5.1
Starting and running the survey
Note:
The first operation to do after turning on the instrument is to check the date and time
displayed by the datalogger; in case of disagreement with the current date and time, update them
(see §
Errore. L'origine riferimento non è stata trovata.
).
M-Log performs the measurements and processings as they always belong to only one survey. The
execution of survey is made in automatic way, few seconds after the starting of instrument.
The features of datalogger configuration can be changed through software 3DOM; after a
configuration change and its transmission to the instrument, all data in the memory will be
automatically deleted and a new survey will start. The data management is allowed by application
software on the PC.
5.1.1
Automatic recognition of probes
M-Log dataloggers complete with inputs with mini-din connectors (series ELO009) are equipped
with function for auto-recognition of probes made by LSI LASTEM.
The inner library of M-Log allows the instrument its auto-configuration according to LSI LASTEM
sensors physically connected to datalogger (for its operation see §4.3.1.3); the library assigns the
respective measurements (acquired and calculated) to each specific recognized sensor and in this
way it automatically setup the configuration with more suitable parameters.
The measurements configured in this library (programmed thanks to experience of LSI LASTEM
engineers) have acquisition times and other management modes in accordance with type of
measured quantity. It’s however possible to modify the configuration parameters (processing time,
acquisition rate, name of the measurement …); in order to carry-out this modification, follow the
instruction below:
1-
open 3DOM software;
2-
download configuration from instrument (see §4.4.8 of SWUM_00339 manual);
3-
modify the interesting parameters (see §4.4 of SWUM_00339 manual);
4-
save the configuration and re-send it to instrument (see §4.4.7 of SWUM_00339 manual).
The programming of new configuration produces the erasing of all data in the instrument
memory; for this reason it’s recommended to transfer data on PC, through same program,
before you setup new configuration.
In order to allow the instrument the right acquisition, the acquisition rates of measurements must be
lower or equal to elaborated rate. During auto-configuration function, one or more measurements,
having acquisition rate higher than rate setup for processing, can be generated in M-Log; to avoid
this possible error, M-Log has been equipped with function of automatic correction that restores the
acquisition rates (if they are higher) equal to elaborated rates automatically.
