DRK156 Dada Resistance igbeyewo

Mita idanwo ti o ni iwọn apo le ṣe iwọn idiwọ mejeeji ati resistance si ilẹ, pẹlu iwọn jakejado lati 103 ohms/□ si 1012 ohms/□, pẹlu deede iwọn ± 1/2.

Awọn ohun elo
Lati wiwọn impedance dada, gbe mita lori dada lati wa ni wiwọn, tẹ ki o si mu awọn pupa wiwọn (TEST) bọtini, awọn continuously tan ina-emitting diode (LED) tọkasi awọn bii ti awọn wiwọn dada impedance.
103 = 1 kiloohm alawọ ewe LED
104 = 10k ohm LED alawọ ewe
105 = 100kohm alawọ ewe LED
106 = 1 megaohm ofeefee LED
107 = 10 megaohm ofeefee LED
108 = 100 megaohm ofeefee LED
109 = 1000 megaohm ofeefee LED
1010 = 10000 megaohm LED ofeefee
1011 = 100000 megaohm LED ofeefee
1012 = 1000000 megaohm pupa LED
> 1012 = LED pupa ti o ya sọtọ
Ṣe iwọn resistance si ilẹ
Fi okun waya ilẹ sinu iho ilẹ (Ilẹ), eyiti o ṣe idiwọ elekiturodu wiwa ẹgbẹ ọtun ti mita (ni ẹgbẹ kanna bi iho). So agekuru alligator pọ si okun waya ilẹ rẹ.
Gbe mita naa sori dada lati ṣe iwọn, tẹ mọlẹ Bọtini idanwo, LED ina nigbagbogbo tọkasi titobi resistance si ilẹ. Ẹyọ ti wiwọn yii jẹ ohms.

Imọ Standard
ACL385 gba ASTM boṣewa D-257 ni afiwe elekiturodu ọna ti oye, eyi ti o le awọn iṣọrọ ati leralera wiwọn orisirisi conductive, electrostatic itujade, ati insulating roboto.
