ETCR2000 clamp type grounding resistance meter

ETCR2000 clamp type grounding resistance meterProduct Introduction

ETCR2000 clamp type grounding resistance meterThis is a major breakthrough in traditional grounding resistance measurement technology, widely used in the measurement of grounding resistance in power, telecommunications, meteorology, oil fields, buildings, and industrial electrical equipment.
When measuring a grounded system with a circuit, there is no need to disconnect the grounding lead or auxiliary electrodes, which is safe, fast, and easy to use.
It can measure grounding faults that cannot be measured by traditional methods and can be applied to situations where traditional methods cannot measure them, because this instrument measures the comprehensive value of grounding body resistance and grounding lead resistance.
There are two types of jaws: long jaws and round jaws. Long jaws are particularly suitable for situations where flat steel is grounded.
In addition, it can also measure the leakage current and neutral line current of the grounding system.

Precautions for use:

A. During the power on self-test, the instrument should be in a relaxed and natural state, and fingers should not touch the clamp handle when holding the instrument with one hand. This is important for ensuring measurement accuracy.
B. When the measured resistance is high (e.g. greater than 100 ohms), to ensure measurement accuracy, before pressing the POWER button (i.e. before the instrument is powered on), press the clamp handle to open and close the clamp 2-3 times, and then start the instrument. This is important for ensuring measurement accuracy of resistors greater than 100 ohms.
C. Always keep the contact surface of the jaws clean. The anti pollution ability of this instrument is already very strong, but excessive pollution can still reduce the measurement accuracy of the instrument. Especially the measurement accuracy of resistors above 100 ohms.
D. The anti drying ability of this instrument is already very strong. There is sufficient resistance to dryness for the current on the tower grounding wire. However, the low-voltage transformer connected to the zero system still needs to undergo power outage testing due to its large unbalanced current.
E. Please remove the battery from the battery compartment when not using this instrument for a long time.
