Hr (Heart Rate) Signal; Hs/Hr (Hand Sensor) Receiver - Technogym RUN PERSONAL Technical Service Manual

RUN PERSONAL + UNITY: Service & maintenance manual - rev. 4.1
6.16. NO HR (HEART RATE) SIGNAL
HUMAN BODY "CONTINUITY": It is statistically recognised that for some people it
is difficult (if not impossible) to measure their HR by Hand Sensors. This may be due
to numerous causes which are able to alter the continuity of the "electrical" contact
between the user's skin and the HS electrodes, such as: hands only just washed or
particularly dry, acidity of the skin and/or a particular body fat mass index. For these
people it's suggested to wear the chest belt.
CORRECT HAND SENSOR USE: Grasp both the upper and lower plate avoiding
clenching them too hardly. Avoid washing the hands using soaps that can dry the skin
too much.

supply power
Components
involved:
Display Board
Receiver Board
Connector cables

Driver
What to do:
Check the
Display Board SW and
the earthing of the
Receiver Board.
Check the voltages input
to the Display Board.
Reconnect and/or
replace
Check that there is NO
continuity between the
HS plates and the earth
on the Cardio Receiver
(to prevent discharges
to earth).
Replace.
Check the voltages
output to the Driver.
