          Product Features
1. The instrument displays three-phase voltage, three-phase current, and three-phase power,
    and automatically calculates the impedance voltage percentage of the transformer,  converting
   to the load loss at rated temperature and rated current. It automatically determines the iron core
   model of the oil-immersed or dry distribution transformer. The instument has an alarm self-adapting
   function during the test, which is convenient for on-site users.
2. The instrument displays three-phase voltage, three-phase current, three-phase power, and the
   distortion rate of the applied power waveform. It automatically calculates the no-load loss of the
   transformer under the rated voltage and corrected the waveform distortion
3. It can be used to check the defects of single-phase transformers or when there is no three-phase
   electricity on site. The instrument can record the data of three single-phase measurements, and can
   calculate the no-load current, no-load loss, impedance voltage and load loss of the transformer
  according to the different connection methods of the transformer.
4. The measurement of zero-sequence impedance is suitable for transformers with a neutral point
   on the high-voltage side, and the instrument can record zero-sequence impedance, zero-sequence
   reactance, zero-sequence inductance, impedance angle, and zero-sequence resistance.
5. The instrument has a built-in rechargeable lithium battery, which can output a three-phase sine
   wave inverter power supply, and the output voltage is automatically adjusted. It has soft start and
   soft stop functions. It does not require any external power supply to achieve the measurement of
   distribution transformer capacity and model judgment At the same time, it shows the transformer
   impedance voltage and the load loss converted to rated temperature and rated current.
6. It can be directly measured within the allowable measurement range of the instrument, and the
   voltage and current transformer can be connected outside the measurement range. The instrument
   can set the ratio of the external voltage and current transformer to directly display the value of the
   applied voltage and current.
 7. The instrument has a harmonic analysis function, which can measure the content rate and tota
   l distortion rate of multiple harmonics, with the original waveform and histogram display.
 8. The instrument uses a large-screen LCD display, which can display three-phase voltage,
   three-phase current, three-phase power, three-phase average voltage, average current, three-phase
   total power and related data on the same screen. Display and use Chinese menu, Chinese
   prompt, simple operation.
 9. AC and DC dual use: lithium battery power supply or 220V AC charger power supply.
10. Intelligent charging management, remaining power display, low battery alarm, automatic
   backlight adjustment to save power.
11. Clock and date display without power failure; data storage methods are divided into local
   storage and USB storage, in which the local storage can store 200 test data, and the local
   storage can be transferred to USB storage; the format of USB storage data is Word ,
   Can be edited and printed directly on the computer.
12. The printing function of the thermal printer is fast and silent.
13. The human-computer interaction interface is more friendly: the status bar at the top of
   the screen displays the plug-in status of the USB flash drive in real time. When operating
   an unconnected device, it displays the corresponding unconnected prompt message.
14. Small size and light weight, easy to carry and use.
