[Voltammeter]ETCR4000 series digital phase voltammetry meter

2026-6-16 16:16:53

1�� Introduction
The ETCR4000 series digital phase volt ampere meter is a carefully designed and manufactured dual channel, multifunctional, digital, handheld measuring instrument for on-site measurement of phase, voltage, current, leakage current, phase sequence, etc. It adopts the latest CT technology and digital integration technology to ensure high precision, stability, and reliability for year-round testing. It is widely applicable in fields such as electricity, metering, communication, railway, petroleum, chemical, metallurgy, construction, scientific research and teaching units, industrial and mining enterprises, etc.
The ETCR4000 series digital phase volt ampere meter can measure the phase between any two phases of voltage (U-U), any two phases of current (I-I), and any phase of voltage and current (U-I) on site. It can also distinguish between inductive and capacitive circuits, determine the phase sequence of three-phase voltage, detect the wiring group of transformers, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, and check the correctness of the wiring of the electricity meter.
The ETCR4000 series digital phase volt ampere meter adopts the latest CT technology. When detecting current, there is no need to disconnect the measured line, and non-contact measurement is required. When detecting the phase between U1-U2, the two inputs are completely insulated and isolated. The housing is made of engineering insulation material and equipped with rubber anti vibration protection sleeve, which effectively ensures the safety of operation and avoids possible short circuits in the measured line caused by misconnection, which may burn out the measuring instrument.
The ETCR4000 series digital phase voltammetry meter adopts a large high contrast blue screen backlit LCD (64 mm × 54mm), which displays clearly at a glance! Its current clamp needle shaped design is particularly suitable for places with dense wiring.
