The system measures vertical Average and Peak Velocity of the weight lifted.
By using the known mass, the system also calculates Average Power, Peak Power and Peak
Force in the concentric phase of weight training.
To calculate Peak Power and Peak Force, the system uses equation:
P = F x v
, where
F = (m x g) + (m x a) ,
g-acceleration of gravity and a-acceleration
The system also measures downward average velocity; rest time between reps or sets;
displacement; concentric, eccentric and total work time.

2.1 Battery Installation
New rechargeable batteries are pre-installed in a battery compartment.
Before the sensor unit is operated, it is necessary to pull out a safety plastic strap from the battery
compartment to release the battery contact. The rechargeable batteries come pre-charged, ready
for use.
The Tendo MyUnit has a built-in battery charger. To charge the batteries, use the AC / DC power
adapter (included).
