Built-in Data Logger
ETL3000/ETLONE is provided with a built-in microprocessor.
The system runs several measuring cycles inside a minute interval, then performs a minute
average.
The arithmetical average is calculated for each channel and data are stored with the
clock/date information.
If the ETL3000/ETLONE is switched off, stored data are kept in the memory and the clock
runs regularly.
When the ETL3000/ETLONE is switched on, the display shows the introducing words
“Environmental monitoring station” , the configuring command for the modem is sent twice
after 1-2 seconds and then the concentration values for all channels are displayed and
updated at the interval of 1 minute
The standard archive stores the
Hourly Averages
with a buffer capacity of 10 days storage.
As an alternative, the ETL can be ordered to store the
15 min averages
, In this case the
buffer storage capacity is only of 2,5 days.
Once the memory buffer is full the new data is overwritten on the oldest data.
The ETLBUS application is provided with a data logger which stores an instantaneous data
every 10” including the GPS data (if supplied) for a total of 14 hours of buffer.
O
nce the memory buffer is full the new data is overwritten on the oldest data.
All concentration values for gaseous pollutants are stored and displayed on the instrument
in volume concentrations, then through the @ COM3000 software, the operator can change
the concentrations in weight or leave them in volume.
As regards the gas and noise measurements, the displayed value is calculated on a
linearization of the calibration curve memorized in the FLASH memory (see set of
commands).
ETL3000/ETLONE with hourly mean or 15' mean, needs to use two different versions of
@COM3000 which are not compatible on the same PC.
The choice of hourly or 15 minutes averages has to be done with the purchase order.
ETLBUS needs to use a specific @COM3000 Software called @COM3000-BUS
