TriLink

Symptom
I pressed the ON key on TriLink
and it did not turn on.
TriLink displays BT_fail during
startup
Bluetooth connections is denied
(even after pairing)
I see voltage units when
sampling using the microphone.
I started a new logging and the
data logger stopped immediately
afterwards.
The recorded data is "noisy"

Cause of problem
•
After pressing the ON key wait 3
seconds for TriLink to "wake up"
•
Try charging the battery, it may be
weak.
•
You are using unsuitable AC/DC
adaptor (see page 12).
•
The USB cable is connected
•
The USB cable is connected
• The microphone is monitoring the sound
wave shape, which is displayed in
voltage units. The sound level,
measured in decibel values, is another
mathematical description of the sound
amplitude.
•
First check if the sampling rate was so
fast that the experiment began and
ended in less than a second. If this is
not the reason, recharge the 2.4V
battery and try again. TriLink monitors
the battery power during the logging. If
the battery voltage is not sufficient, the
logging is stopped automatically.
•
With voltage or current sensors, use
short connections between the circuit
being tested and the sensor. In some
cases it is advisable to connect the (-) of
the current sensor to the ground
terminal
•
Avoid working near strong
electromagnetic fields. (e.g. engines,
fluorescent lights )
