FR945 PulseOximeter - Scale on the right and allDay mode

Former Member over 4 years ago

Hello everybody

I have two questions about the pulse ox of my fr945

1. If I go to the pulseOx widget I see two scales: the one on the left goes from 90 to 100 and is fine. The one on the right is a bit odd... it goes from 2k to 4k. I read it should be my altitude.. but i have never been a such altitudes (they should be in meters according to my user setting) with my watch. Even if they were in feet, I never got at 2k feet with my watch.. What do I misunderstand?

2. I see that the pulseOximeter has the modes Off / DuringSleep / AllDay.

However I read that in order to have an accurate reading i should stay completely still with wrist at the height of heart for 20/30 seconds.

This is something that almost never happens during my days (probably this is true for everybody).

What would then happen if i turned the mode to AllDay? Would I get a bunch (100%) of inaccurate readings?

Thanks in advance!

The green bar at the top is the SpO2, using the left scale.

The grey graph along the bottom is the altitude, using the right hand scale.

Any ideas? especially on the scale on the right?

Hi, the scale is in meters for me. The gray area in the graph should be your altitude. What altitude are you on?

For me, 400m elevation is correctly displayed. Can you post a screenshot?

As for the PulseOx, I have it on all day, but it really is just a gimmick. It definitely has an offset in general and I wouldn't trust it.

All right.. I see thanks.. It was a bit misleading to see such a huge scale (up to 4000m) given the fact that I spend all the time at around 400m... I was expecting a narrower scale (like 200m-600m or something like that).
