DRK156 Whakamatau Atete Mata

Ka taea e tenei mita whakamatautau te rahi o te pukoro te ine i te impedance o te mata me te parenga ki te whenua, me te whanuitanga mai i te 103 ohms/□ ki te 1012 ohms/□, me te tika o te awhe ±1/2.

Nga tono
Hei ine i te kaha o te mata, tuuhia te mita ki runga i te mata hei ine, ka pehi me te pupuri i te paatene ine whero (TEST), ko te rama-rama (LED) e tohu ana i te nui o te inenga mata ine.
103=1 kiloohm LED matomato
104=10k ohm LED matomato
105=100kohm LED matomato
106=1 mega ohm LED kōwhai
107=10 megaohm LED kōwhai
108=100 megaohm LED kōwhai
109=1000 megaohm LED kōwhai
1010=10000 megaohm LED kōwhai
1011=100000 megaohm LED kōwhai
1012=1000000 megaohm LED whero
>1012=aramarama whero weweti
Ine i te ātete ki te whenua
Whakauruhia te waea whenua ki roto i te turanga o te whenua (Ground), e whakamau ana i te taha matau o te hiko o te mita (kei te taha o te turanga). Honoa te topenga alligator ki to waea whenua.
Whakanohoia te mita ki runga i te mata hei ine, ka pehia me te pupuri i te paatene TEST, ko te rama marama tonu e tohu ana i te nui o te aukati ki te whenua. Ko te waeine o tenei ine he ohms.
paerewa hangarau
Ka whakamahia e te taputapu te tikanga whakarara D-257 paerewa ASTM mo te whakarara i te hiko hiko, ka taea e ia te ine i nga ahuatanga rereke, te tuku hiko, me te whakamaarama.
