Troubleshooting error 70-11
Possible cause 1: The strip was not inserted within the time limit on the Insert strip screen.
Start the test again and insert the strip when prompted by the analyzer.
Possible cause 2: Wine has entered the strip port and is preventing the meters sensor pins from detecting an inserted strip.
Clean the analyzer strip port with lint-free paper.
Note: Flooding may be indicated if a strip is removed from the analyzer with traces of wine on the top of strip (separate from the porch).
To clean the strip port with lint-free paper:
- Remove the protective cap that sits over the Sentia strip port.
- Using absorbent, lint free paper, carefully blot up any excess liquid from the inside of the protective cap and strip port face.
- Cut a fresh piece of lint-free paper to test strip width (or less). Gently insert into strip port. Do not force.
- Remove paper (taking care to remove it all)
- Repeat steps 3-4, until paper comes away clean.
Note: While cleaning spills, always keep the strip port pointed downwards to avoid getting liquid into the analyzer.
Possible cause 3: A non-wine residue has been introduced to the strip port and is preventing the meter sensor pins from detecting an inserted strip. E.g., paper lint.
IMPORTANT: always use lint-free paper when cleaning the Sentia strip port.
You may choose to clean the analyzer strip port with ethanol.
To clean the strip port with ethanol (+ used test strip):
1. Follow steps 1-2 as above for a lint-free paper clean.
2. Add a small amount of reagent grade ethanol (≥ 95%) into a beaker or other small vessel - enough to cover the electrode legs of a Sentia test strip (~10mm/0.4 inches).
3. Briefly dip an old/used test strip into the ethanol to wet it. Then give this strip a few shakes to remove excess solution.
4. Insert wetted test strip into the strip port.
5. Move the inserted strip back and forth in the strip port with a gentle push-pull motion. Repeat this motion four times.
6. Repeat steps 2-5 another three times.
7. The strip port should now be clean. Replace the strip port protective cap and leave the device to dry for 10-15 minutes.
