View Full Version : Erratic Polar HRM Readings
Erratic Polar HRM Readings
I have a Polar S625X HRM which has similar functions to the Polar 725. I have been getting erratic readings no matter where I am at. In the city, out in the country side, etc... The erratic readings are in the cadence and speed. I get max speeds of 65 to 70+ mph and max cadence of 170 to 200. I wished I could go and spin that fast but unfortunately I can't. I will be contacting Polar but I wanted to see if anyone has had the same problem and what they did to fix it. My sensors are in the recommeded mounting locations and heart rate is usually within range.
I am considering selling the Polar and going with a Cateye Wireless.

sounds like you're using the wireless sensors. They can pick up interference from some sources and give readings like you're describing. I have the wireless system on one of my bikes and have seen the same thing...depends on where I ride however.
I don't know about the Cateye Wireless, but I suspect this is something you can find with most wireless systems.
Not much help I know, but that's probably what's causing the issue.

my wireless flips out whenever i ride next to high voltage power lines. are there lots of those on your route?

I don't have the Polar model with cadence and all of the other nifty fuctions, but the plain hrm model is affected by all sorts of things - things that my husband and I have noticed especially -being around lots of other people using wireless hrm's, those invisible fences that are used for dogs, and the cart retention system at our local Safeway. We think the fences and the cart system may work on the same principle. They all make the hr read out shoot up to 211.
I have a cateye wireless computer (not a hr or cadence model) as well, and the two do not interfere with one another, but the speed reading on the cateye flips around a bit. It usually is flips around lower to accurate. I think the sensor does not always make accurate contact, especially if it is bumpy. I think it may be a trade off of going wireless, but I kept breaking wires so I'm happy to go with it. Plus it works fine in the rain, which my husbands wired computer does not do and rain we have plenty of here in Seattle.
i get hr readings of 220+ when i leave the house... i live at 600m+ sea level and its a fast downhill but its only when i leave... i dont get it riding back up.... very wierd....
I haven't had many problems with mine at all. I use the wireless cadence and speed sensor with my s520. I do get an higher speed reading on occassion, but thats it. I have all the sensors turned up to the highest "broadcast" range--not sure if that would make a difference or not. I haven't done many rides in large groups lately, but the ones I have done I don't get much interferance either.
I was thinking of turning up the power on the sensors to the max on mine. I would be willing to give up some battery life for accurate readings. I have 2 bikes and they both give erroneous readings. I'll try that. I am the only one that I know of on my group rides that uses a Polar. I have tried using it in different environments and it seems to consistently give false maximum readings.
Another quirky thing is that the odometer will not give separate readings for each bike. I figure that if there are settings for bike 1 and 2, there should be separate counters for each.
Thanks for your replies.

My old polar HRM does this with powerlines as well - also when when salt and oils from sweat bridges the contacts on the chest unit : note check state of batteries .

Are you in a tuck? At times I've seen my HR readings shoot up between 200-230 (from 120-130) when I get the transmitter (on my chest) too close to the receiver (on the stem of my bike...)

I suppose we could all go back to using wires.
