Troubleshooting

The OneTouch® Ultra® 2 Meter displays messages when there are problems with the test strip, with the meter, or when your
blood glucose levels are higher than 33.3 mmol/L or lower than 1.1 mmol/L. Messages do not appear in all cases when a
problem has occurred. Improper use may cause an inaccurate result without producing an error message.
In this section, screens that display "SEE OWNER'S BOOKLET" means you should refer to this User Guide.
TROUBLESHOOTING AND DETAILED INFORMATION ABOUT YOUR SYSTEM
Message What it means
You may have a very low blood
glucose level (severe hypoglycaemia),
lower than 1.1 mmol/L.
You may have a very high
blood glucose level (severe
hyperglycaemia), over 33.3 mmol/L.
Meter is too hot (above 44°C) or
too cold (below 6°C) to work
correctly.
There is a problem with the meter.
Error message could be caused either
by a used test strip or a problem with
the meter.
What to do
This may require immediate
treatment according to your
health care professional's
recommendations. Although this
message could be due to a test error,
it is safer to treat first and then do
another test.
Re-check your glucose level. If
the result is HIGH GLUCOSE again,
obtain and follow instructions
from your health care professional
without delay.
Wait a few minutes and insert a
new test strip. If you do not get
another TEMPERATURE ERROR
message, the meter is now within
the operating range.
Do Not use the meter.
Repeat the test with a new test strip;
see Section 3, Testing your blood
glucose.
