- How many readings are held in the meter's memory?
- What happens once the memory is full?
- What altitude can I use my meter at?
- Can I change the units of measure in my meter?
- My reading is 'HI'; what does 'HI' mean?
- I keep seeing a rectangle with a '-' and '+' on the screen. What does that mean?
- I keep getting an E-1 error on the screen. What does this mean?
- How many batteries does the meter need?
The FreeStyle Optium can store up to 450 events, including control solution, blood glucose and blood β-Ketone results.
The FreeStyle Optium has a rolling memory; once you reach 450 events, the oldest event is replaced with a new reading.
Clinical testing demonstrates that altitudes up to 2,195 metres (7,200 feet) above sea level does not affect the FreeStyle Optium's results.
The FreeStyle Optium meter is supplied only in the UK and Republic of Ireland with the unit of measure as: mmol/L
After a test on the FreeStyle Optium, if the reading is 'HI', this means your reading is higher than 27.8 mmol/L
This sounds like the 'Battery Icon'. Your battery is getting low and needs replacing as soon as possible.
E-1 usually means the FreeStyle Optium is either too hot or too cold to work correctly. Move the meter and test strips to a location where the temperature is within test strip operating range.
The FreeStyle Optium requires 1 x CR2032 v3 Lithium battery.
