res: ETCR033H High Voltage Clamp Leakage Sensor is specially designed for high voltage current measurement, uses the latest CT technology with unique automatic plug function, composed of special detection clamp and high voltage insulation rod; the integration design of clamp and lead area ensures high-precision, high-reliability and high stability year-round uninterrupted testing.  ETCR033H High Voltage Clamp Leakage Sensor can be used in the measurement of high voltage line current, currents on both sides of transformer, variable ratio test, online current monitoring below 60KV, safe and time saving. If not use insulation rods, it can also be used as high-precision low-voltage clamp current and current leakage sensor to accurately measure 1mA current or current leakage. It is widely used in power plant, substation, industrial and mining enterprise, inspection station, electrician maintenance department for current sensing, power audit and field working. Insulation rod is light and convenient, with the characteristics of moisture resistance, high temperature resistance, anti-impact, anti-bending, high insulation and scalability.  2.Specifications:                Function        High voltage AC current, low voltage AC current, high and low voltage variable ratio, current leakage testing                 Clamp Mode        Clamp CT                 Dimension        Width, height, thickness: 76mm×255mm×31mm                 Clamp Dimension        Φ33mm                 Output Signal        Mutual inductance current signal or voltage signal (model selection)                 Voltage Signal        Full range output 0-3VAC or 0-2.5VDC (external 5VDC power supply)                 Measuring Range        0.00mA-600A                 Resolution        0.01mA                 Accuracy        0.
