Can I check my readings while I am exercising?

Any movement can cause the device to reset its readings. If you are in the middle of exercising, we advise to take readings during resting phases while the body is not mobile. If you have finished, wait 10-15 minutes before taking a reading.

What is the SpO2 and pulse rate range the pulse oximeter can register?

The digital pulse oximeter is able to measure SpO2 between 70% and100%, and pulse rate between 30 and 250 beats per minute (bpm).

Can the 500E-B Pulse Oximeter be used on children?

Yes. However we recommend our children pulse oximeter instead – specifically designed for smaller fingers. The larger finger chamber of the 500E-B may be too big for children with small fingers, affecting its accuracy.

How do I know the battery is low?

The battery icon will display the low power indicator. Please replace the batteries.

Why does the reading fluctuate and why is the reading different on different fingers?

It is normal and natural for your SpO2 and pulse rate to fluctuate as the amount of arterial blood pulses and changes with each heartbeat. A ±3 fluctuation in your SpO2 is considered normal.
