BulletPoint6 : The clamp contact surfaces must be kept clean, cannot rubbed with caustics and coarse material. Avoid any impact onto this tester, especially the clamp jaw contact surface. Confirm that the tester and accessories are in good condition, and the meter and test line insulation layer is not damaged, exposed or disconnected before use. During measurement, it is forbidden to touch bare conductors and the measuring circuit loop. Confirm that connector plug of line has been inserted in the tester interface closely. Please don’t supply over 100V AC or DC voltage between testing device and interface. Otherwise, the tester may damage. BulletPoint7 : Clamp Meter Resistance Measurement Principle The basic principle of the clamp earth resistance tester measure earth resistance is measuring the loop resistance, as shown in the figure1. The clamp jaw part of the tester is comprised of voltage coil and current coil. The voltage coil provides excitation signal, and will induce a potential E on the measured loop. Under the effects of the potential E, the current I generate on the measured loop. The meter will measure E & I, and the measured resistance R can get by the following formula: R=E/I BulletPoint8 : 3-wire method & 4-wire method Resistance measurement Principle The 3-wires and 4-wires method measures the grounding resistance value measurement by the rated current pole-changing method (suitable for accurate measurement of single-point grounding system), that is, the AC rated current I flows between the measuring object E grounding pole and the C (H) current pole, The potential difference V between the grounding pole of the E and the voltage of the P(S) voltage, and the grounding resistance value R is calculated according to the formula R=V/I.
