The Pythagorean Measurement
There are 4 modes for measuring triangular distance with Pythagorean
Theorem. It creates convenience for users to carry out indirect
measurementincomplexenvironments.
1. Press the " " button 3 times or the " " button once. The
hypotenuse of " " will ash on the display. Press the " READ " button
tomeasurethelengthofthedottedhypotenuse(a)accordingtothe
instructions on display. Press the " READ " button to measure the length
ofthedottedangleside(base)(b).Thedevicewillautomatically
calculatethelengthofthesolidright-angleside(height)(x).
2. Press the " " button 4 times or the " " button twice. The right-angle
side of " " will ash on the display. Press the " READ " button to measure
thelengthofthedottedright-angleside(b).Thedevicewillautomatically
calculatethelengthofthesolidhypotenuse(x).
3. Press the " " button 5 times or the " " button 3 times. The
hypotenuse of " " will ash on the display. Press the " READ "
buttontomeasurethelengthofthedottedline(a)accordingtothe

Note: In the Pythagorean measurement mode, the length of the
right-angle side must be less than the hypotenuse, or the wrong signal
indicator will be shown on the display. To ensure measurement accuracy,
measurementmustbetakenfromthesamestartingpointfollowedbythe
hypotenuse, then the angle side.
Cumulative and Regressive Measurement Function
Single distance can be measured by cumulative or regressive operation of
plus/minuscalculation.Userscanusethe" +" button to enter cumulative
and regressive function after getting the single distance measurement
result. Press the " +" button or the " +" button, "+" appears on the main
display area and enter cumulative measurement mode. Display shows the
cumulative value of last measurement value and current
measurement value.
Holdthe" +" button or press the " +" button. On the main display, "-"
will appear and enter regressive measurement mode. Display shows the
difference value of last measurement value and current measurement value.
The area and volume can be accumulated and subtracted, as well as the
distance.Thefollowingexamplesillustratethecumulativeandregressive
function area, to which cumulative and regressive of volume are similar.
Area accumulation: Measure the rst area to get a result as shown in
gure 1. Press the " +" button or the " +" button to measure the
second area and get a result as shown in gure 2, and a plus sign will be
shownintheleftbottomcorner.Lastly,pressthe" READ " button to get the
sum value of these two areas. The result is shown in gure 3.
