There are four DC currents to select for HYZC-40 which has a large output power,the power of the tester itself is very little. Used four lines, it is quick,stable,high precision for testing the winding resistance. In addition, it has a strong ability for anti-jamming ,over current ,over voltage and discharge. the security is also very high, So it is a ideal tester for testing various resistances especially the sensibility equipment.

3. Notice:

1. Make sure that the equipment to be tested is out of electricity and unconnected with others and the ground pillar is connected to the earth firmly before you start to test;

2. Check the supply power: AC220V±10% 50Hz;

3. Make sure the U+(U-) is inside of the I+(I-),otherwise a error will occur;

4. The test wires must not be cut off until the buzzer is stopped and the indicator light is off when testing the inductance object, otherwise an accident will occur;

5. The tester is verified, you cannot verify it if without any special case;

6. If the fuse or other devices are to be replaced,please use the same model;

7. Make sure the tester is far from oil and water when you store it, the temperature range is -10～50℃,and the relative humidity is not more than 95％,there is not caustic gas in the store room, Please do not strike it strongly.
