APPENDIX A
TROUBLESHOOTING
Symptom:
After being in a damp, cold environment, the logger does not
function.
Cause, Correction:
Condensation may have formed inside the logger,
shorting out the circuitry and discharging the battery. Allow the circuit
board to dry thoroughly in a warm location.
Symptom:
Simple Logger
®
II does not start recording.
Cause, Correction:
Make sure battery power is present. Make sure
the PRESS button is pushed long enough to light the GREEN LED and
released before the next LED lights. Make sure the RED LED is not
double- blinking. If it is, memory is full and you need to erase the data (see
§
3
.7). Make sure the SLII is properly configured
so that you have Storage
Rate, Recording Period and at least one Measurement Channel specified
Symptom:
Cannot find the instrument when pairing the Bluetooth con-
nection.
Cause, Correction:
Make sure the Blue LED is single blinking, indicating
that the instrument Bluetooth module is active.
Symptom:
Even though the pairing of the Bluetooth is established and
the LED indication is active, the instrument will not connect to the
Simple
Logger
II
Control Panel.
Cause, Correction:
Make sure the Low Battery LED is not blinking. If the
batteries are below 2.2V the instrument will have enough power to run the
circuit but not enough to maintain a stable connection. Replace the bat-
teries.
