ETCR4000 Double Clamp Digital Phase Voltammeter is a multifunctional instrument specially designed for field testing, with high accuracy, high stability, low power consumption and easy to use and other features. It can direct measurement of AC voltage and AC current in the measured circuit which not open-loop, measure the phase between two voltages, two current and voltage current, and indirectly measure the power factor and power of the circuit. Distinguish three-phase phase sequence, transformer wiring group, inductive and capacitive circuit, test secondary circuit and bus differential protection system, Read out the phase relationship between each group of CT in differential protection, check whether the wiring of the electricity meter is correct or not, overhaul the line equipment etc.

ETCR4000 Double Clamp Digital Phase Voltammeter adopt super large LCD display screen , digital high 40mm , and with white screen backlight , display clear and obvious, shows the exquisite and luxurious appearance.

ETCR4000 Double Clamp Digital Phase Voltammeter suitable for electric power, petrochemical, metallurgy, railway, meteorology, industrial and mining enterprises, scientific research institutes, metrology departments, etc.
