Pulse Heart Rate Diagnostics:
Heart Rate Receiver / Chest Strap Diagnosis:
1. There should be a constant 4.5Vdc – 5Vdc across the brown & black wires on the heart rate receiver
harness. If you measure 0Vdc across those two points, then the remote control console is bad.
2. If the heart rate receiver is working properly, this is what you should see on your voltmeter.
TABLE A – (Without Transmitter)
WIRES Vdc OHMS
BROWN & BLACK 5 Vdc 6.13m OHMS
BROWN & RED 5 Vdc 0m OHMS
BLACK & RED 0.7 Vdc 0m OHMS
If the heart rate receiver is working properly with your pulse simulator or chest strap, this is what you should see
on your voltmeter.
TABLE B – (With Transmitter)
WIRES Vdc OHMS
BROWN & BLACK 5 Vdc 0m OHMS
RED & BLACK 0.1 – 0.4Vdc 0m OHMS
RED & BROWN
Voltage will fluctuate from
2.9 Vdc – 4.9 Vdc
(Fluctuation gets faster as
you increase your heart
rate)
Ohms will Fluctuate from
6.10m ohms – 20m ohms
(Fluctuation gets faster as
you increase your heart
rate.)
If you get the readings from TABLE B and the upper display board still will not show a heart rate output
then the upper board has failed.
If the heart rate receiver is not working properly with your pulse simulator or chest strap, this is what you should
see on your voltmeter:
TABLE C – (Heart Rate Receiver Failed)
WIRES Vdc OHMS
BROWN & BLACK 5 Vdc 0 ohms
RED & BLACK 0.1 – 0.4 Vdc 0 ohms
RED & BROWN
2.9
(Reading will be steady)
6.10 OHMS
(Reading will be steady)
