Polar CS400 Speed Readout Delay

stevieboy

I've just bought a CS400 HRM and everything works fine, but the speedo takes about 5 seconds to respond to movement. Once it's being read it tracks the speed perfectly albeit about 5 seconds behind actual speed and when i come to stop it takes 5 seconds to respond back to zero. I admit that I never took much notice of my previous speedo but I don't recall it being this slow.

Is this normal (does it when installed on stem and an inch from sensor)?
