Zc-205a DC resistance tester of our company adopts new power technology, which has the characteristics of small volume, light weight and large output current. The whole instrument is controlled by single-chip microcomputer, which can automatically complete self inspection, data processing, display and other functions, with automatic discharge and discharge indication functions.
DC resistance tester with power supply
This paper introduces the use of its power supply:
A. DC power test:
Close the power switch, the power indicator is on, press the "start stop" key, and then select the corresponding resistance gear switch for testing. After the test, press the "start stop" key, and the "discharge" indicator light will be on (if the stored power of the tested object is small, the "discharge" indicator light will not be on). After the discharge, the "discharge" indicator light will be off, and then the test clamp will be changed for another test.
B. AC power test:
Connect the AC AC220V power supply, the corresponding indicator light (charging indicator light or full indicator light) will be on, close the power switch, the power indicator light will be on, press the "start stop" key, and then select the corresponding resistance gear switch for testing. After the test, press the "start stop" key, and the "discharge" indicator light will be on (if the stored power of the tested object is small, the "discharge" indicator light will not be on). After the discharge, the "discharge" indicator light will be off, and then the test clamp will be changed for another test.
C. Charging:
Connect the AC AC220V power supply, when the "charging" indicator light is on, it means that the inductive load tester is being charged. If the rechargeable battery in the instrument has enough power, the "full" indicator light will be on. At the same time, the battery in the machine is charged. (the DC resistance tester is designed with a charging protection circuit, and there will be no overcharge.)
Finally, it should be noted that in the case of strong electromagnetic field interference, it is recommended to use DC power supply for test. In this state, the test value is stable and the power frequency interference resistance is strong.
Zc-205a DC resistance tester has the advantages of high testing accuracy and simple operation, which can realize the fast measurement of the direct resistance of the transformer, and is very worth purchasing. In addition, if you don't understand, you can always consult our online customer service for details.
