Introduction to Handheld Digital Dual Clamp Phase Voltage Ampere Meter

　　CJVA-20BHandheld digital dual clamp phase voltmeterHaving the characteristics of intelligent instruments (such as measurement/storage/query/output/printing functions), it is widely used in the power industry for relay protection, maintenance companies, power installation and other departments. It is also suitable for detecting the secondary circuit of power lines in large power consuming enterprises such as chemical, metallurgical, mining, railway, etc.

Main purpose:

Distinguish the positive and negative phase sequence of the line;

Measurement of electrical parameters for power lines;

Determine the speed of operation of the electricity meter, calculate the correction factor, and collect electricity fees reasonably;

Detecting the wiring group of transformers and the secondary circuit wiring of relay protection;

Distinguishing between inductive and capacitive circuits;

Can be equipped with a high current clamp meter for power line loss management data collection;

　　Main functions and characteristics of handheld digital dual clamp phase voltmeter

Adopting a 65X50 LCD display screen with high brightness backlight, displaying 3 sets of data on one screen, the interface is intuitive and clear.

Direct function key operation, automatic range switching without shifting gears.

Measure the true effective value of voltage and current, as well as the phases of U-U, U-I, and I-I. Real time measurement of electrical parameters such as active power, reactive power, apparent power, power factor, and frequency.

The dual channel symmetrical design ensures mutual insulation, safety and reliability. It can detect and distinguish the wiring group of transformers. When measuring the U-U phase value, the two voltage input circuits are insulated and isolated, which will not cause a short circuit in the tested line or burn out the instrument.

The current amplitude and phase characteristics are flat, and the phase can be accurately measured within the range of 5mA-10A.

Equipped with a pointed nose clamp shaped current transformer, it has high measurement accuracy and strong anti-interference ability, making it particularly convenient to use in situations with dense wiring.

The instrument is simple to use and easy to operate, making it very suitable for use as a wiring discrimination training tool and teaching instrument in various power schools.

The instrument has an automatic power-saving management function, which automatically recognizes the working status, does not shut down during operation, and can automatically shut down when no one is using it.

Ultra small streamlined structure, anti drop wristband design, handheld, small size, light weight.

Optional data storage function for querying, uploading, and printing reports of on-site data.

Optional online real-time data recording function, connected to a computer to collect on-site data and draw curve graphs.
