Large Caliber Single Phase Clamp Power Tester Meter Gauge with RS232 Interface
Introduction
★ETCR7300A Large Caliber Single Phase Power Tester is well designed and manufactured for measuring three phase AC voltage, current, leakage current, phase between current and voltage, phase between phase voltage, frequency, power energy, phase sequence, active power, reactive power, apparent power, power. It is a multifunctional, digital, intelligent tester. Its large caliber 80mm×80mm can clamp electric cable of 80mm diameter, or 96mm×4mm flat cable and steel earth wires. It has all the functions of Large Caliber Leakage Clamp Meter and Micro Power Clamp Meter. Besides, it also has this functions such as distinguish transformer wiring group, inductive and capacitive circuits, test second circuit and bus differential protection systems, read the phase relationship between CTs of the differential protection, check the meter wiring right, repair lines and equipment, etc. Provide operators with a safe, accurate and convenient tester.
★ETCR7300A Large Caliber Single Phase Power Tester’s clamp core is made of special alloy, adopt the latest magnetic shielding techniques, can almost shield the influence from external magnetic field, to ensure the high precision, high stability and high reliability of perennial uninterrupted measurement. The meter can store 200 sets of data, with RS232 interface, upload stored data to the computer through the system software, implementing online real-time monitoring, historical inquires, dynamic display. With the function of historical data read, preserve, print, and backlight, data hold, etc. It is a necessary tool for electrical safety testing.
