Question about Timex Digital 30 Lap Heart Rate Monitor 5C401
Timex Model M515Incorrect readings when using a TIMEX Heart Rate Monitor - despite changing bateries twice and cleaning the electrodes on chest strap.Wore another HRM (simultaneously)to compare and TIMEX is off and drifting / jumping by several tens of beats - sometimes just "maxes" out at heart rate of 240 and gets "stuck @ 240. The watch functions just fine, the timers, stopwatch etc is OK. Issue is just with Heart rate monitor portion.This is my best HRM and I hate to just leave it in the drawer!
I´m experienced the same problem of incorrect readings after a long time without use. I cleaned the rubber parts of the chest strap with soap and water, than I use some silicone grease or other silicon liquid to keep the rubber hydrated. Make a careful cleaning in the contact area between the rubber and the plastic parts, the fissure in these area use to be full of "sweat dust".
