Simple Logger
®
II Model CL601
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:
The instrument 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 § 4.7).
Make sure the Simple Logger
®
II is properly configured so that you have
Storage Rate, Recording Period and at least one Measurement Channel
specified.
Symptom:
The instrument does not respond to a button press even with
fresh batteries installed.
Cause, Correction:
Make sure that the instrument is not OFF. Press the
button for a short duration (less than 0.5 seconds). If the LEDs do not
flash, then the instrument is OFF. Turn the instrument ON by pressing the
PRESS button for two seconds. The LEDs will light solid once the instru
-
ment has turned on and you may release the button at that time.
Symptom:
The instrument does not communicate; LED’s blink dimly at a
fast rate.
Cause, Correction:
This is a fault condition that can be resolved by man
-
ually erasing the memory (refer to §4.7).
