and replace the controller if there is any error
E32
The controller detected that the
motor was running in the
opposite direction for more than
one week.
Check whether there is anything that forcibly makes the
motor rotate in the opposite direction, check whether the
motor is installed normally, make sure that there is no
problem, and see whether the electronic watch returns
E32 error, and if there is any replacement of the motor or
controller
E33

Hand Pulse Technology
Our products come equipped with hand pulse sensors which are used to pick up tiny EKG/ECG signals
that run through the body when your heart beats. These electrical EKG/ECG signals are very small and
that they must be amplified 1000 times to make the signal useful for the computer to display your pulse.
To ensure proper operation:
- The user must maintain good, consistent contact on all four sensors
- The users skin cannot be too dry or too wet
Other factors that could affect the reading:
- Change of grip on the sensors (during slow pace walking and up to running)
- Tightening of hand muscles will produce small electrical signals
- Static electricity charges from the air or from walking on the treadmill
EKG/ECG Sensors may filter through actual EKG/ECG signals and “Noise” factors that may affect the
reading. This will cause the pulse reading to be delayed and will take longer to update the display as the
heart rate changes. Too much noise will create an incorrect reading. Medical conditions or having no
electrical signal in the hands are other factors that may affect pulse readings as well.
These are limitations of hand pulse technology and even the most expensive systems (which can cost
upwards of
$3,000) used in hospitals have the same problems. The difference is that a patient in a hospital is not
running on a treadmill. Hand pulse technology works well on stationary exercise machines like bikes and
even elliptical cross trainers but are not perfect on a treadmill. We offer treadmills with a wireless heart
rate receiver which may be a more accurate option.
To test if your hand pulse sensors are working up to speci
fi
cation, hold them while standing on the side step
rails, not walking, and see if the reading is more in line with what you would expect. This will eliminate the
movement and static electricity factors. If your hands are dry, then wet them slightly (saliva works as a great
conductor if this doesn’t bother you).
