Using the Master in vehicles
The most efficient way to program the loggers and read out data
is to drive slowly through the transmission range of the loggers
in a vehicle with the
Master
. This is generally preferable to a foot
patrol. It is important to ensure a stable radio connection between
the
Master
and loggers for the data transmission.
Note:
When programming the loggers from a passing vehicle it is im-
perative to always maintain the radio connection.
The
Master
aerial can be swapped for a
magnetic antenna at-
tachment which is placed on the vehicle roof
to improve the
reception quality.
The magnetic antenna attachment is available to buy as an ac-
cessory.
It should be noted that the unit will drain power from the vehicle
battery when the engine is not running if this is used as an
exter-
nal power source
for the
Master
(using the TG8 docking station
and M4 vehicle cable). The
Master
should, therefore, always be
switched off when not in use.
