Question 3: Irregular heart rate reading
Answer 3:
a) The most common reason for irregular readings
especially at the beginning of exercise session is
that there is no proper connection between skin
and the electrodes of transmitter. To ensure a
proper connection, electrodes should be wetted
prior to exercising.
b) Elastic strap is too loose allowing transmitter to
move during exercise.
c) Ensure that there is no anyone else wearing a
transmitter in the reception area of your receiver.
If there are other transmissions close to you
crosstalk may appear, unless you are using the
coded Products Polar products.

d) Pacemaker and other implanted devices may
change the electrical characteristics and
operation of heart so that transmitter detects
several beats instead of one beat.
e) Some people have a reversed ECG signal
compared to normal a ECG signal possibly
causing a transmitter to send two pulses for each
heart beat. Please turn transmitter upside-down.
f) Interferences. Electrical equipment such as
monitors, motors, LED displays, transformers
switches, cellular phones and etc. generate
electromagnetic noise which may cause missing
or extra pulses resulting in incorrect heart rate
reading.
