Heart rate readout has returned!
This morning I was looking into the possibility of either replacing the PM3 with a PM5. Or getting a new heart strap. Or even the possibility of doing both. Before making a decision regarding those choices, I re-visited the rowing machine, unplugged all three cables (USB cable to desktop computer which runs RowPro, cable connecting PM3 to rowing machine’s Power Generator Assembly and the cable connecting the PM3 to the heart rate signal receiver). After looking at the plugs of all three cables, I plugged them back into the PM3.
Also, I removed and checked the heart rate receiver, which is mounted under the rowing machine rail. Then I re-placed the heart rate receiver back to its location under the rail.
After that, I donned one of the 2 heartstraps and got a heart rate readout. Then, I switched to the other heartstrap and also got a readout from that one.
So though I don’t know why there was no readout yesterday, the problem seems to have been cured.
Today’s training session was an easy 6K with an additional warmup and warmdown totalling another 4K. Same as yesterday, but it was done with more enthusiasm with HR readout on screen.
Happy rowing to you.
