Actually See Your Result
Write your information in black and white. Whereas our terminal is convenient enough to be detected, there are instances that you will be faced with the scenario whereby there are numerous sets of data that require to be looked at. You could easily do this by connecting the terminal to a printer and it can be configured and printable at the same time.
Wider Measurement Range
It possesses a more extensive span of measurement. Current and voltage have an additional broad range of measurement. TA - 272 -3P is capable of measuring a wide range of current with 500:1 range in order to provide accurate measurements. Its actual display is 10000:1 with a minimum start - up current of 1mA and also high voltage can be metered.
We Are the All-Mighty
We can be even greater than your fantasy. TA - 272 - 3P will be able to fulfil the regular testing parameter requirements and will be capable of being configured with a printer. In addition, with no pulse meters, TA - 272 - 3P may operate the electric energy accumulation.

Case
Product Case
A national energy service provider experienced constant difficulties in making sure that three-phase energy meters in industrial parks and commercial complexes are accurate. Technicians used several misaligned tools to verify meter error, diagnose a wiring problem and measure electrical parameters- created fragmented data, increased on-site operations and hard to resolve billing error or inefficient energy use.
The TA-272-3P Three-phase Calibration Terminal was able to deal with these pain points with its all-in-one design. It integrates accurate error calibration, total parameter measurement (voltage, current, power, 2 nd to 51 st harmonics), and wiring fault detection into a single instrument.
It has USB, Bluetooth, and WIFI connection and therefore allows transfer of data smoothly to central systems, and has adaptive communication features which makes it compatible with different meters.
The terminal is highly accurate even when dealing with large current ranges which avoids the use of guesswork when diagnosing problems and using the compensation to determine the electricity.
