ZC29 Grounding Resistance TesterDetailed product description：

ZC29 Grounding Resistance Tester

Overview:
The ZC29B grounding resistance tester is suitable for measuring the resistance values of various power systems, electrical equipment, lightning rods, and other grounding devices. It can also measure the resistance value of low resistance conductors and soil resistivity.

This instrument complies with the industry standard ZBN21012 of the People's Republic of China for grounding resistance meters.

Technical features:

1. The measurement range and accuracy are shown in the following table:

model	Measurement range Ω	Minimum division value Ω	Accuracy%
ZC29B-1	0-10	zero point one	three
	0-100	one
	0-1000	ten
ZC29B-2	0-1	zero point zero one
	0-10	zero point one
	0-100	one

2. The auxiliary grounding resistance affects the change amount. When the auxiliary grounding resistance changes from 500 Ω to the specified value in the table below, the allowable change amount should not exceed the specified value in the table.

Auxiliary grounding resistance (Ω)	0	one thousand	two thousand	five thousand
Allow variable to be changed for percentage representation of grade index (%)	one hundred	one hundred	one hundred	two hundred
