The Metravi CAL-ER Earth and Ground Tester Calibrator is used for calibrating grounding resistance testers, equipotential testers and other instruments which require a standard resistor.

It is widely used in building quality inspection stations, supervision companies, construction companies, lightning protection companies, electric power departments, etc.

Features:

• Connection: 4-wire method
• Insulation Resistance: 10MΩ above(between the circuit and shell 500V)
• Safety Standards: IEC61010-1,CAT ? 600V,Polluted Gradation
• The military grade instrument is composed of 9 pieces of 1/2w, high-precision, military-grade wire- wound resistors.
• It has stable performance and strong structure, especially convenient for calibration & testing. When calibrating resistors, one can direct shift and test without replacing the test line.
• Fully meets the national weather service order "lightning protection device detection qualification management approach" specified in the range of 10-3 ~ 105 Ω.

Range & Accuracy:

• 0.001Ω; 2%
• 0.01Ω; 0.5%
• 0.1Ω; 0.2%
