Transformer Test Equipment 100KΩ Touch screen LCD DC Resistance Tester
Main features
1. Be operate by Android mobile phone or tablet
2. Maximum output voltage of instrument -24V, convenient to select a larger test
current when the resistance value is high, so as to improve the test speed
3. Use new power supply technology, with many current ranges and wide measuring range.
Automatically select the current according to the load. Suitable for DC resistance measurement
of small and medium-sized transformers and voltage transformers.
4. With many protection functions, such as back EMF impact, wire breaking and power-off during the test,
overheat of power supply and so on.
5. With function of any temperature conversion of copper and aluminum materials, touch to input any
winding temperature and conversion temperature.
6. Intelligent power management technology, the instrument works in the minimum power state,
effective energy saving, reduce heating.
7. Seven inch high brightness touch color LCD, clear display under strong light, full touch screen operation,
free switching between Chinese and English.
8. With own calendar clock and power-off storage, which can store 1000 groups of test
data and can be consulted at any time.
9. With Blueteeth communication, RS232 communication and USB interface for computer
communication and USB data storage.
10. Test results can be printed.

Points for Attention
1. It is necessary to wait until the discharge is over and the alarm stops before removing the wiring, otherwise it is dangerous.
2. When measuring the no-load voltage regulating transformer, the discharge must be reset before the reverse tapping, and the tapping point can be switched only after the alarm stops.
3. When selecting the current, refer to the range in the technical index column. When the current exceeds the range, the instrument is always in the "charging" state because the current cannot reach the preset value. At this time, press the reset key to reset the instrument and select a smaller current gear again. Under the range, the display "current is too small", when the two states appear, to confirm the range, select a larger current for testing.
4. After the test, press the "reset" key, the power supply of the instrument will be disconnected from the winding, discharge at the same time, sound alarm, and the ammeter will return to the zero position. At this time, the display will return to the initial state. After the discharge sound is over, the wiring can be reconnected for the next measurement or the test line and power line can be removed for bundle measurement.
