KD2571B2 Ground Resistance Meter

　　It is used to measure the ground resistance of various grounding devices. The four-wire method can avoid the influence of lead resistance. It can also measure soil resistivity, resistance of low-resistance conductors and ground voltage.

　　Features

• 　　Using synchronous detection and other technologies, it has strong anti-interference ability.
• 　　The four-wire method can eliminate the bow-line resistance error by measuring the grounding resistance.
• 　　Adopt digital microprocessor, 3 1/2LCD large-screen digital display, with backlight and reading lock function.
• 　　Two working modes, 10 seconds short timing, 5 minutes long timing, automatically stop the test and lock the reading, accompanied by sound and light prompts.
• 　　can measure and calculate soil resistivity.
• 　　Built-in large-capacity lithium battery, equipped with a special charger, can work continuously for about 8 hours, the battery symbol shows the power level, and has a battery under-voltage alarm function. Dry batteries can also be used as a backup power supply for the instrument.
• 　　When the measured earth electrode is open or the auxiliary earth resistance of the current electrode is greater than the upper limit, there will be an open circuit "OPEN" indicator.
• 　　has a shock-proof, dust-proof and moisture-proof structure to adapt to harsh working environments.
