Product Introduction

ETCR4020 Large Caliber Double Clamp Digital Phase Voltmeter, also known as single-phase phase voltammeter, digital phase voltammeter, voltammeter, phase measuring instrument, is used to measure two-way AC voltage, current, phase between voltage, phase between current, phase between voltage and current, frequency, phase sequence, active power, reactive power, apparent power, power factor, etc., to determine the transformer wiring group, inductive, capacitive circuit, test the secondary circuit and the female difference protection system, read out the phase relationship between the CT of the mobile protection group, check whether the wiring of the meter is correct or not, and overhaul the line equipment , etc., to provide electricity inspectors with a safe, accurate and convenient new type of power meter.It is especially suitable for electrical energy billing systems and relay protection systems, electrical energy metering, electricity consumption inspection, and power audit in the power supply marketing department, and meter installation and reception, relay protection, differential detection, start-up testing, substation maintenance, or power training, skill competitions, etc. in the biotechnology department.
ETCR4020 Large Caliber Double Clamp Digital Phase Voltmeter adopts a 2.8-inch TFT color LCD screen, and all parameters are displayed on the same screen, which is clear at a glance.It is a comprehensive upgrade of the mechanical knob-type phase voltammeter, which reduces the cumbersome operation, reduces the possibility of misoperation, and has high test accuracy and easy to use.The instrument is equipped with anti-vibration, non-slip, high-insulation sheath, USB communication interface, can store 1200 sets of data, upload the stored data to the computer through the system software, realize online real-time monitoring and historical query, read, save, report, print historical data, etc.
1. Large-caliber current pliers are used, which are suitable for testing of thick wires and high currents.
2. Input by voltage transformer and current clamp, there is no high voltage in the machine, and the two inputs are completely isolated, which is safe and reliable.
3. The pointed and small jaws are suitable for places with dense wiring.
4. The test line adopts a special power cable, and the elastic rod plug and alligator clip are insulated and protected.
5. Storage function, 1200 sets of data storage.
6. USB communication interface.
