Note: Additional explanation on the day change
Basic setting Day change over Meter reading of the
counter module red line
Measurement cycle 1min. Measurement value blue line
The highest value of the day was already achieved at
the time of the last measurement before the day change
(no new pulses between the time of the last
measurement and day change) The highest value of the day is recorded at the time of
the first measurement after the day change (new pulses
between the time of the last measurement and day
change)
5.3 ALOHA transmission mode
ALOHA transmission mode is a special connection mode whereby the myDatalog4 establishes a
connection to the myDatanet server for 10min.
InitiatingALOHA transmission mode:
l
Directly on the device using the solenoid switch (see "Solenoid switch" on page 57). The GSM
network is re-selected during this process. This means that a list of all of the GSM networks in
the receiving range of the device is created from which the first GSM network is then selected
that is not on the "Ban list" (see "Ban list" on page 29) and that is part of one of the service
providers supported by the integrated SIM card (see www.microtronics.at/footprint).
A speech bubble in the measurement instrument list (see "myDatanet Server Manual " 805002)
with the title "Aloha" indicates that a device is in ALOHA transmission mode.
Clicking on the speech bubble with the "Aloha" title opens the ALOHA data window (see
"myDatanet Server Manual " 805002). It contains the internal "Battery" and "GSM level"
measurement values. The measurement values for the last thirty minutes are always shown in the
ALOHA data window, which means that data from a previous ALOHA transmission may be included.
The ALOHA data is generated every three seconds independently of the normal measurement value
and is thus not saved with the standard measurement data.
