Recommended Deployment
•
Position the loggers in a shady/sheltered area where
possible. This helps to avoid the elements effecting the
accuracy of your data.
•
I
t’s
a good idea to chain and padlock your instrument in
place if
it’
s situated in a publicly-accessible area.
•
If used in a wet-well situation, ensure the instrument is
situated above the
‘h
igh-wate
r’
mark, the instrument is
not meant to be submerged.
•
Consider the nature of the gas being measured, some
gases are
‘heavy’
and will naturally accumulate close to
the floor/ground of the area being logged.
•
The amount of air movement in the deployment area can
affect the accuracy of gas reading measurements taken.
Ensure that there is sufficient air flow to allow natural
diffusion of target gas to where the instrument is taking
readings. Too much air flow may mean target gas passes
too quickly over the sensor for the sensor to respond.
•
I
t’s
common for the Odalog to be placed into areas
covered by thick concrete and/or metal covers. It is
important however that the signal can still transmit when
deployed. Ensure reliable communication continues
during
‘
start-up
’
mode when all covers/lids are closed on
the area. It should be noted that if the open-air signal is
poor, it is likely the signal will be noticeably less or unable
to connect when placed into a shielded deployment area.
•
The Odalog G20 RTX uses wireless transmission to
connect to the internet server, communication can
sometimes be disrupted by other similar devices and
electrical interferences by nearby equipment. Ensure the
Odalog is not placed near high voltage cables or
electrical machinery (e.g. pumps).
Signal Strength
The signal strength (as per the last transmission, NOT real-
time), will be displayed in the STATUS screens as a number
“%”
under the SIGNAL heading. The symbol on the INST
screen will also give an approximation of signal strength by
the number of segments present:
The above figure displays the different segments of the Signal
Strength.
