Troubleshooting
The A160 logger will not power on.

Check that the AC adapter is plugged in to an outlet and the
A160.

Use a paper clip or toothpick to press
“

”
on the base of the
logger.
The readings on the LCD don
’
t change.
Check to see if the display is in maximum or minimum mode.
“
Bat

and the green LED keep flashing.
The adaptor output voltage is not 5VDC (±10%), 500mA. Please
ensure you are using the correct adapter.
Why won
’
t the logger connect with the computer?
The COM Port settings may need to be changed in SpecWare
software.
I accidentally sprayed water on my A160.
If you haven
’
t done so already, unplug the AC adapter. Shake
any water out of the A160. Set the A160 in a ventilated area for
at least a day, preferably more. Do not plug it in until you are
confident that any water has evaporated. Water damage is not
covered under warranty.
