A. Lamp-house and standard frame choice

Open the case, select the correct uniformity lamp-house (example the outside Dispersion lamp), require the illumination of the bright side is same (the illumination Min is zero), The max can clear the “lobat 1999” on the display, if can’t clear should weaken the Illumination)

B. Press the power switch

It display(the tolerant is 5000 standard board, unit is cm2 Memory is zero), press the zero button, the instrument display the stochastic number, Adjust the zero adjust screw, sketchy first then adjust the inching, let it disply 000, put The standard board on the measure board, if according to the error require, let the Object on the measuring board, cover the press board, them measure the area.

C. Standard board sum the result

If the oject area is bigger than the measure board, we can divide into small part, then Sum the result.

For example, the first area is 210cm2 , press the measure button (m) it display “lobat210” Press the memory button(m+), it display 11 character. Then press the zero button(z), it display The stochastic number, adjust the zero button (z), take the object on the measure board, for Example it display 198cm2 , press the measure button(m), it display lobat198cm2 , press the Memory button(m+), then display 11 character, the result memories. If need measure and memory several time, only press the rm button, it can display the memory Button. If it not exceed 999, it will display directly, if exceed 999, it only display two character for Example lobat13, press the rm second time, display 084, so the memory is 13084. If the memory is over 65535, it display 88, it means the memory is overflow, it need press rm, Then can read the result, the result is before the last time measured. If need to measure continute, Should press rst button, clear the memory.

Not euphotic leaf we think the s1=s2 (s1 mean the measure result, s2 mean the real area) if the Leaf euphotic is too much, s1

How to got rate of the euphotic?

Take the standard board on the measure board, take something clearly cover the object, for

Example, use the 150 standard board, with cover the clearly thing, the result is 144, if cover with

Opacity thing the result is 150, so the rate of the euphotic isη = (s-s)/s * 100%

Η -- -- mean the rate of the euphotic

S---- mean measure area cover with the opacity thing.

S ---- mean the real area

S=s * (1+η)

For example if measure the leaf s=98cm2

Η = (100-98)/98*100%=2.0408%

S = 98*(1+20.408%)=99.99cm2

Actually the thick of the leaf not as same, so the euphotic rate is not same, we need to measure The rate for every leaf.
