Ⅳ: Functional Characteristics About The DC Resistance Test:

1. For large transformers whose five-column core and low-voltage windings are connected in delta, the instrument can use the method of high and low-voltage series excitation for testing. The instrument automatically connects the magnetizing circuit of the windings, which can quickly and accurately test the DC resistance of the low-voltage windings.

2. 7 inch high resolution LCD touchscreen, easy on-site operation. Good visibility even under strong light.

3. The instrument is equipped with three-phase test function, in order to complete the three-phase direct resistance measurement in one connection of the star-connected winding, and automatically calculate the three-phase unbalance rate, which greatly saves the measurement time and improves the work efficiency. The phase-by-phase test function can also be used to perform phase-by-phase tests on transformers with YN and D(Y) connections until the test is completed.

4. Comprehensive protection circuit and sound discharge alarm, clear discharge indication.

5. Easily set the test winding, tap position, phase, test temperature, converted temperature etc.

6. Internal data storage up to 100 sets.

7. RS232 port and USB Port for data storage and PC communication.

8. Built-in high-speed micro printer.

Ⅳ: Safety Measures When Doing the Test:

1) Must read this manual carefully before using the tester;

2) The tester operator should understand the common knowledge on general electrical devices or instruments;

3) The tester can be used indoors and outdoors, but it should be protected from rain, corrosive gas, excessive dust, and high temperature;

4) The tester is a precision instrument and any severe vibration must be avoided;

5) The tester should be maintained, repaired and adjusted by professionals;

6) After the test, be sure to wait for the discharge alarm to stop before turning off the power and removing the test wires;
