Netefatsa hore lihlahisoa tsa k'hamphani li fihlela litlhoko tsa bareki, li fana ka motheo oa tlhahlobo ea sehlahisoa, le ho netefatsa boleng ba sehlahisoa.

Boholo ba ts'ebeliso

Tekanyetso ena e sebetsa ho lihlahisoa tsohle tsa module ea TFT e hlahisoang ke XX.

Lisebelisoa tsa Teko

Mochini oa ho lekanya oa motlakase, sesebelisoa sa liteko, khalase e hōlisang, lebone la fluorescent, caliper ea vernier

Morero oa mehlala le ho lekola maemo a tikoloho

Yuniti ea tlhahiso (kapa ts'ebetso ea QC) e etsa tlhahlobo e felletseng bakeng sa tlhahlobo ea ponahalo le tlhahlobo ea ts'ebetso ea motlakase, le bakeng sa litekanyo tsa boholo kapa tlhahlobo e ikhethileng, sekhechana sa pele sa mofuta ka mong se sampuoa le ho lekoa li-5pcs.

Yuniti ea boleng e lekanya li-5pcs bakeng sa sampole ea pele ea mofuta o mong le o mong, mme e sebelisa GB / -2012 tlhahlobo e tloaelehileng ea moralo oa nako e le 'ngoe bakeng sa tlhahlobo ea ponahalo, mme boemo ba tlhahlobo ka kakaretso ke II.
