Instrument Status Icons - LANDTEC GEM5000 Operating Manual

GEM5000 Gas Analyzer

6.3 Instrument status icons

The following icons may be displayed on the instrument screen:
Icon Description
Battery charge state
Gives the operator an
estimation of the battery
charge state. For example
100% gives about 8 hours
use in the field and 50%
would mean that there is
approximately 4 hours
battery life remaining.
Pump status
This icon is displayed
along with a counter
showing the pump run-
time. This counts down
where the operator has
specified the pump run-
time; if not it counts up;
the icon turns red when
stalled.
GPS signal strength
This icon shows the signal
strength the analyzer's
GPS module is able to
provide. Full, okay and fair
strength respectively.
This indicates when
Bluetooth has been
enabled. The color
changes from gray to blue
when connected.
Data logging
This icon indicates that the
data logging feature is in
operation.
Legacy mode
This icon indicates that the
analyzer is in legacy mode
and hence is ready to
connect to a PC.
Icon Description
Battery charge state
Indicates less than 2 hours of charge
remaining.
Pump stalled
This icon is displayed when the pump
stalls. The instrument's gas inlet (or
outlet) may be blocked. This warning is
most commonly caused by a water-
logged or dirty sample filter. Change the
sample filter and check for obvious
blockages in the sample tubes.
Alternatively, a small amount of
adjustment can be made to the low flow
detection point to compensate for minor
changes in the performance of the pump
fitted to the instrument.
GPS failure
The GPS was unable to get a line of sight
lock on enough satellites. Or, it may be
that it hasn't had time to get a lock.
Language
This icon indicates the currently selected
operating language. This can be changed
via the main menu.
Service overdue
This icon indicates that the analyzer is
overdue for service
USB disabled
This icon indicates that the analyzer has
reached a battery critical state, and
hence has turned off its USB
connectivity.
