What to do if there are no characters on the display of HemoCue Measuring Instruments?
- MMrs. Christina BeckSep 23, 2025
If there are no characters on the display of your HemoCue Measuring Instruments, it could be due to: 1. The analyzer not receiving power. Check that the power adapter is connected to both the analyzer and the AC power supply, and ensure the cable isn't damaged. 2. If using battery power, the batteries may need to be replaced. Turn off the analyzer and replace the batteries with 4 type AA batteries.
