Domestic multifunctional ratio tester with small size

Multi functional ratio tester

Performance characteristics:

1. Dual use of AC and DC: lithium battery power supply or 220V AC charger power supply adaptive.

2. One charge can continuously measure the transformation ratio group of 100 transformers.

3. Intelligent charging management, remaining battery display, low battery alarm, automatic backlight adjustment, saving power.

4. The fully three-phase sine inverter power supply outputs with automatic voltage regulation and features soft start and soft stop functions, resulting in fast testing speed and high accuracy.

5. Three phase transformer, single-phase transformer, PT, Z-type transformer ratio, group, polarity testing function.

6. It has blind testing function, which means conducting ratio and group tests without knowing the high and low voltage connection methods.

7. CT variable polarity testing function.

8. It has angle difference testing function during single-phase testing.

9. The tap gear can be tested up to 197 gears.

10. The testing range is wide, up to 10000.

11. High and low voltage reverse connection protection function.

12. Output short-circuit protection function.

13. Clock and date display without power failure; The data storage methods are divided into local storage and USB storage. Local storage can store 500 pieces of test data, and local storage can be converted to USB storage; The USB flash drive stores data in Word format, which can be directly edited and printed on a computer.

14. Thermal printer printing function, fast and silent.

15. Small size, light weight, easy to carry and use

Notes:

1. During the measurement period, do not touch the test sample.

2. If the test line is short circuited and the high and low voltages are reversed, the fuse will be blown. After the fuse is blown, if measurement is taken, the LCD screen will display the words "Measuring, please wait!" and then stop. At this point, please shut down, replace the fuse with the same capacity, and retest.

3. The connection should maintain good contact, and the instrument should have good grounding!

4. The workplace of the instrument should be away from strong electric fields, strong magnetic fields, and high-frequency equipment. The smaller the interference from the power supply, the better. It is recommended to use lighting wires. If the power interference is still significant, the instrument can be powered by an AC purification power supply. The capacity of the AC purification power supply should be greater than 200VA.

5. When the instrument is working, if there is disorder in the LCD screen display, no response when pressing all buttons, or if the measured value is far from the actual value, please press the "reset" button, or turn off the power, and then operate again.

6. If there are no characters displayed on the LCD screen or the colors are very light, adjust the brightness potentiometer to the appropriate position.
