Characteristics of LCD display automatic ratio tester

High quality fully automatic ratio tester

Product Introduction:

It is a new generation intelligent transformation ratio testing instrument that uses a microcontroller as the core for measurement calculation and automatic control, with a fully Chinese menu operation interface. It has the advantages of intuitive display, good stability, high accuracy, wide measurement range, and does not require three-phase power supply on site.

Performance characteristics:

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

2. Fast testing speed, completing single-phase testing in 7 seconds.

3. 240 * 128 color LCD display screen, with a more intuitive interactive interface.

4. Z-shaped connection transformer test.

5. It has the functions of blind variable ratio testing and group testing.

6. Non power-off clock and date display, data storage function (can store 50 sets of test data).

7. The protection function of high and low voltage reverse connection.

8. Transformer short circuit and turn to turn short circuit protection function.

Product Features

1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.

2. Internally equipped power supply, automatically generating three-phase high-power test power supply.

3. It can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.

4. It can automatically perform waveform distortion correction, temperature correction, voltage correction, and current correction (short-circuit test under non rated current conditions). Operators only need to input the correction index instrument according to the transformer type to automatically calculate the corrected results, which is very suitable for units that do not have slightly larger capacity transformer short-circuit test conditions.

5. Voltage circuit width limit: The voltage can be measured up to 750V without switching gears to ensure accuracy. The instrument itself will not be damaged due to incorrect voltage gear selection.

6. The function of indicating the percentage of remaining battery power is not simply a low power alarm.

6. Large screen, high brightness LCD display, full Chinese character menu and operation prompts for friendly human-machine dialogue, touch buttons for easier operation, wide temperature LCD with brightness adjustment, suitable for winter and summer seasons.

7. Users can print out the results of the test data at any time through a micro printer.

8. The test result storage function can store 200 sets of capacity test data.

Technical Indicators:

Range: 0.9 to 10000

Accuracy: ± (reading x 0.1%+2 words) (less than or equal to 500)

± (reading x 0.2%+2 words) (greater than 500 but less than or equal to 3000)

± (reading x 0.3%+2 words) (greater than 3000)

10～99.999（0.001） 1000～9999.9（0.1）

4. Working power supply: built-in battery or external charger, charger usage conditions, input 100-240VAC, 50/60Hz

Charging time: about 5 hours

6. Instrument weight: 3.5Kg

7 Instrument volume: 260mm (length) x 200mm (width) x 160mm (height)

Notes:

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

If the test line is short circuited and the high and low voltage are reversed, the fuse will melt. After the insurance is blown, if measurement is performed and it shows' measuring in progress', please wait! Stop afterwards. Please shut down, replace the fuse with the same capacity, and retest.

3. The connection should be protected to ensure good contact. The instrument should be well grounded!

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 cables. If the power interference is still significant, the instrument can be charged using AC purification power cables. The capacity of the AC purification power supply should be greater than 200VA.
