• Instruction Manual

Turn on the power, 'Welcome to the KEDO test instrument', press the 'start' button, voice prompt 'please test' to start doing sit-ups, record the number of sit-ups completed in one minute, the final test score is announced by voice; after completing one action, there will be a buzzer to indicate the count; when you complete one, if you do not hear the buzzer, it means your action is not standard or in place, and you should make adjustments in time.

The subject lies down fully on the test bench with their legs slightly apart and their knees bent to about 90 degrees. Their fingers are crossed and placed behind their heads, and their feet are placed in the footrests of the test bench to fix their lower limbs. When the subject sits up, if their elbows touch or exceed their knees, it counts as one complete action.

Lie down with both shoulder blades touching the test platform. The test probe detects two positions: 1, the back should be against the mattress, and 2, the position where both elbows touch or exceed the knees, counting once for each rotation.

The entire testing process is accompanied by voice synchronization prompts. Please follow the prompts to operate. If you want to disable the voice function, press the 'Voice Key'.
