Operation method of DC resistance tester

1. Before use, check whether the input and output lines are intact. After confirming, plug in the power cord. At this time, the power indicator lights up, indicating that the power line is connected. If there is an abnormal phenomenon, After checking the cause, deal with it.

2. Check whether the range of the voltmeter is appropriate and whether the voltage regulator is above the zero position. When selecting the range, choose according to the actual situation. When measuring the resistance of the whole machine and measuring isolation, electric poles and grounding, etc. When the resistance is different, their required ranges are different.

3. When connecting the output line to the test product, pay attention to placing the current line outside the voltage line. When starting the test, make the test product in a proper connected state, and set the DC resistance tester to the When the button is pressed, the indicator light turns on.

4. Adjust the voltage regulator so that the current evenly rises to the corresponding current value. Observe the change of the pointer. If there is any deviation, it must be modulated at any time to ensure the accuracy of the detection. After the detection is completed, it is necessary Make a test record for later review.

When using the DC resistance tester, you must be proficient in the operation method and take safety precautions. If the resistance tested by the sample is found to be abnormal, the DC resistance tester must be calibrated first, or renewed Perform a test to see if the data is very different, if it is not normal, repair it.
