Product Introduction

The ground resistance measuring instrument is a new type of ground resistance measuring instrument which combines the three-end button and four-end button measuring methods by using advanced medium and large scale integrated circuit instead of the traditional manual manual power generation.

The working principle is that the DC/AC converter in the machine changes DC into low-frequency constant current of AC and the circuit is formed by auxiliary ground electrode C and measured object E which generates AC voltage drop on the measured object and is fed into AC amplifier for amplification through auxiliary ground electrode P and then sent to the meter head for display through detection. With the aid of multiplying power switch three different quantity limit can be obtained: 0 ~ 2 Ω 0 ~ 20 Ω 0 ~ 200 Ω.

The earth resistance measuring instrument is suitable for measuring the earth resistance of various devices and the conductor resistance value of low resistance in electric power post and telecommunication railway communication mining and other departments. The table also measures soil resistivity and ground voltage.

Product Characteristics Product Characteristics

1、The grounding resistance measuring instrument is constructed with high-strength aluminum alloy as the casing. In order to prevent industrial frequency and rf interference the phase-locked loop synchronous tracking and detection mode is adopted on the circuit and the switch capacitor filter is equipped to make the instrument have better anti-interference ability.
2、DC/AC conversion technology is adopted to convert DC into AC low-frequency constant current for easy measurement.
3、 Allow auxiliary grounding resistance of 0 ~ 1.8kω (RC) 0 ~ 40KΩ (RP) shall not affect the result of measurement.
4、the grounding resistance measuring instrument does not need manual adjustment and balance 3(1/2) position LCD display in addition to measuring the earth resistance but also can measure low resistance conductor resistance soil resistivity and ac voltage. If the test circuit does not display &ldquo on the header; 1 & throughout; Stands for overflow in line with conventional measurement habits.
