HZ-3340D 40A 3 Channels Transformer Winding Resistance Tester

hz-3340d

HZ-3340D three-channels 40A DC resistance tester is an electronic device used to test the resistance value in DC circuits. It is characterized by a three-phase power input and a maximum current output of 40 amperes, and is equipped with a high-precision resistance testing device. The tester uses a digital display screen to display measurement results and has real-time data input and output functions, enabling fast and accurate testing and analysis of the circuit. In addition, the tester can also perform polarity testing to confirm that the circuit connection is correct and functioning properly. This tester is widely used in fields such as power systems, electrical engineering, manufacturing, and scientific research.

Safety Measures

1.Be sure to carefully read the operation manual before using the instrument.

2.The instrument operator shall have general knowledge about the use of general electrical equipment or instruments.

3.The instrument can be used both indoors and outdoors. However, be sure to avoid using it at the following places with rain, corrosive gas, too high dust concentration, high temperature, or direct sunlight, etc.

4.The instrument is a high-precision instrument; therefore, it is required to avoid severe vibration of the instrument, and some shock absorption measures shall be taken during transportation.

5.Repair, maintenance and commissioning of the instrument shall be performed by professional personnel.

6.To ensure personal safety, a reliable ground wire shall be connected before turning on the power; in addition, the ground wire shall be removed after removing the power.

7.It is forbidden to dismantle and move test clips and power supply lines during test. The test lines can be removed after discharging alarm sound is ended upon test completion.

8.For no-load voltage regulation winding, it is forbidden to switch the no-load tap changer when test is being conducted or discharging is not completed.

9.When the power supply suddenly fails during the test, the instrument will start to discharge automatically. At this time, it is forbidden to immediately remove the test lines; they can be removed after the discharging alarm sound is ended.
