How to Troubleshoot Error #5 in a One Touch Ultra Mini

The OneTouch UltraMini is a small glucose meter that can be carried in a pocket or purse. It is operated with only two buttons and can hold 500 test results in its memory. The meter is simple to operate and will provide an error code to assist in diagnosing problems that occur during glucose testing. If error code number 5 -- Er5 -- appears on the display screen, troubleshoot the meter to correct the problem and achieve accurate testing results.

Instructions

• 1

  Check the display on the meter. If it displays "Er5," there is a problem with the test strip. Using a damaged test strip or failing to apply enough blood during testing causes this error code.

• 2

  Discard the test strip and repeat the glucose test with a new strip. Inspect the new strip for damage. If it is visibly damaged, discard it and use an undamaged test strip.

• 3

  Insert the test strip into the port on the OneTouch UltraMini. A blood drop icon will appear on the display when the meter is ready for testing blood glucose.

• 4

  Lance your fingertip with a lancet to obtain a fresh sample of blood. Touch the blood sample with the end of the strip so that blood is drawn into the channel. Hold the strip on the sample until the channel is filled. Avoid scraping the strip against the skin.

• 5

  Watch the display. Test results appear after five seconds. If the meter displays the error code again, use a new bottle of testing strips. The strips may be old or damaged.
