How to fix HemoCue Glucose 201 Blood Glucose Meter showing ERROR code 900-930?
If the HemoCue Blood Glucose Meter shows ”ERROR” and a digit code 900–930, turn off the analyzer and turn it on again after 30 seconds. Take a new microcuvette and repeat the measurement. If the problem continues, see specific error code below.
Why does my HemoCue Glucose 201 display ” ”?
If your HemoCue Blood Glucose Meter displays a blank screen showing only ” ”, it likely means the batteries need replacement. Turn the analyzer off and replace the batteries with 4 new AA type batteries. If you're using a power adapter, check that it's properly connected and working. If the problem persists, the analyzer may need service.
Why are measurements on patient samples higher or lower than anticipated with my HemoCue Glucose 201 Blood Glucose Meter?
If measurements on patient samples are higher or lower than anticipated when using your HemoCue Blood Glucose Meter, it could be due to several factors. Check the expiration date and storage conditions of the microcuvettes. Remeasure the sample with a new microcuvette, and check for air bubbles, using a new microcuvette if needed. The optronic unit may need cleaning. If these steps don't resolve the issue, the analyzer may require service.
Why my HemoCue Glucose 201 Blood Glucose Meter has no characters on the display?
If your HemoCue Blood Glucose Meter displays no characters, it could be due to several reasons. First, ensure the analyzer is receiving power by checking the power adapter connection to both the power source and the analyzer, and inspect the adapter wire for damage. If using battery power, replace the batteries with 4 new AA type batteries. If the issue persists, the display may be faulty, and the analyzer needs service.
What to do if my HemoCue Glucose 201 displays 'HHH'?
If your HemoCue Blood Glucose Meter shows 'HHH', it means the measured value exceeds 444 mg/dL (24.6 mmol/L). Check the expiration date of the microcuvettes and remeasure the sample with a fresh microcuvette.
What does error E08 mean on HemoCue Medical Equipment?
Error E08 on your HemoCue Medical Equipment indicates a light-blocking item in the cuvette holder. Ensure the analyzer and microcuvettes are used according to the HemoCue Glucose 201 RT operating manual and the package insert.
What does error code E06 mean on HemoCue Medical Equipment?
Error code E06 on your HemoCue Medical Equipment indicates an unstable blank value, possibly because the analyzer is too cold. Turn off the analyzer and allow it to reach operating temperature.
What does error code E70-E71 on HemoCue Medical Equipment mean?
Error codes E70–E71 on your HemoCue Medical Equipment suggest a faulty cuvette or a possibly lipemic sample. Verify the system is used as instructed. Fill a new cuvette and perform the measurement again. If the error code persists, use a suitable laboratory reference method to analyze the specimen.
What does E00 error mean on HemoCue Medical Equipment?
The E00 error code on a HemoCue Medical Equipment indicates either a faulty cuvette or a circuit board issue. First, check the expiration date of the microcuvettes and try a new microcuvette.
What does error E09-E30 mean on HemoCue Medical Equipment?
Error codes E09 to E30 on your HemoCue Medical Equipment typically indicate a dirty optronic unit or a faulty electronic or optronic unit. Turn off the analyzer and clean the optronic unit as described in the Maintenance section.
