Press to measure the length of one leg (a)
Press to measure the length of the middle
side (b).
Press to measure the length of another
side (c).
Device automatically calculates the length of
hypotenuse (x).
Press to measure the length of one leg
according to prompts on the screen (a)
Press to measure the length of one leg (b)
Press to measure the length of another side (c)
Device automatically figures out the length of
right-angled side (x)
In Pythagorean measurement mode, the
right-angled side must be less than the length
of the hypotenuse before the instrument can
calculate, otherwise the instrument will display
an error signal prompt. In the Pythagorean
measurement mode, in order to ensure the
measurement accuracy, it is necessary to ensure
that the measurement is from the same starting
point, and the measurement is performed in the
order of the hypotenuse and the right-angled side.
