How to fix a HemoCue Medical Equipment with no display?
If your HemoCue Medical Equipment display is blank, it could be due to a lack of power, depleted batteries, or a faulty display. First, ensure the power adapter is correctly connected to both the power supply and the analyzer, checking for any cable damage. If using battery power, replace the batteries with four new AA 1.5 V batteries.
How to troubleshoot error codes on HemoCue Medical Equipment?
If your HemoCue Medical Equipment displays an error code, try these steps: Turn the analyzer off, wait 30 seconds, and then turn it back on. Use a new microcuvette and repeat the measurement. If the error persists, consult the specific error code details.
What to do if HemoCue Medical Equipment shows error E07?
If your HemoCue Medical Equipment displays error code E07, it indicates low battery power. Replace the batteries with four new AA 1.5 V batteries after turning off the analyzer. Alternatively, use the power adapter.
How do I resolve HemoCue Medical Equipment error codes E01-E05?
HemoCue Medical Equipment error codes E01 through E05 usually 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.
Why does my HemoCue Medical Equipment display show blank spaces?
A blank display on your HemoCue Medical Equipment could mean the batteries need replacing or there's an issue with the power adapter or circuit board when using AC power. Replace the batteries with four new AA 1.5 V batteries after turning the analyzer off. Also, verify that the power adapter is correctly connected and functioning.
Why are measurements on control materials out of range on my HemoCue Glucose 201 Blood Glucose Meter?
If measurements on control materials are out of range (too HIGH or too LOW) when using the HemoCue Blood Glucose Meter, consider these potential causes: the microcuvettes are beyond their expiration date, damaged, or improperly stored; the optical eye of the microcuvette is contaminated; the control has not been mixed well or is not at room temperature; air bubbles are present in the microcuvette; the optronic unit is dirty; the control is not suitable for use with the HemoCue Glucose 201 system; the calibration of the analyzer has been changed; or the controls are beyond their expiration dates or have been improperly stored. To address this, check the expiration date and storage conditions of both the microcuvettes and the control materials. Remeasure the sample with a new microcuvette, e...
What does error 911 mean on my HemoCue Blood Glucose Meter?
If your HemoCue Blood Glucose Meter displays error code 911, it means that the analyzer cannot detect a valid EEPROM memory configuration. You can try turning off the analyzer and then turning it back on after 30 seconds to retry testing. If the problem persists, the analyzer needs service.
What to do if my HemoCue Glucose 201 Blood Glucose Meter shows error 930?
If your HemoCue Blood Glucose Meter displays error code 930, the electronic “SELFTEST” failed. Turn off the analyzer and allow it to reach room temperature. If the problem continues, the analyzer needs service.
What to do if my HemoCue Glucose 201 Blood Glucose Meter display gives erroneous characters?
If the display shows erroneous characters on your HemoCue Blood Glucose Meter, it indicates that the analyzer needs service, as either the display or the microprocessor is out of order.
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.
