What could be the cause of a spike in a temperature channel in ValSuite while all
other channels remain constant?
A battery failure and a disconnected sensor have similar results in ValSuite. The
temperature will spike just before the data logger shuts down. One way to
differentiate between the two is to check the temperature just before the spike. It
is a good indication that the battery is dead, if the temperature drops just before
the spike. If the temperature immediately spikes, a disconnected sensor may be
the issue. This pertains to all loggers and sensors. Before sending a sensor / logger
in for service, verify the results in ValSuite first and, if necessary, run a voltage test
on the battery.
What temperatures should the data loggers be at before being returned to the
reader station?
If the loggers are too hot or too cold to be held by hand, they are not to be placed
in the reader station.
When I read my logger, it gave me no data. What can cause this?
Option 1 – Broken Sensor:
If the reader station slot turned green and the data appears in graph, the logger
read ok. Check the data and see if there is 1 sample around -62°C or +62°C. If this is
the case the sensor must be exchanged to a new.
Option 2 – Dead battery:
It is possible for a battery to have enough power to be recognized, but not enough
power measure and store samples. Test the battery in the activator and replace it if
necessary.
Option 3 – The data logger was refreshed:
If the data logger was started and had turned green, but was refreshed while still in
the station, it will stop before being placed in the process. Therefore, any data
logger that turns green should not be refreshed.
I replaced the battery in my LyoPro data logger, but I still get a low/critically low
battery warning when I try to start it?
The error messages are collected on the data loggers last read. If the battery was
replaced, start the data logger for a few minutes and then read it. If the error goes
away the unit is ready to be used.
