The resistance tester includes microprocessor technology, and the measurement accuracy will be further improved in order to ensure the safety of its use process. It is used to test the DC resistance of transformers, motors, transformers and other equipment. Temperature range: working temperature 5 degrees Celsius to 49 degrees Celsius. It has the advantages of high precision, good retestability, single-button operation, simple and easy to use, and introduction of the calibration method of the resistance tester.
Step 1: Open the watch cover, and be careful not to damage the two wires connecting the power switch on the circuit board. Locate the three correction regulators on the lower right of the circuit board; make the watch at least 1/2 hour under this environmental condition, and then start the test after achieving self-balance.
Step 2: Connect the crocodile clip at one end of the cable and the banana plug at the other end. Connect all ends of the resistor with alligator clips. Three correction regulators, the top is "humidity" measurement, the middle is "impedance", the bottom is "temperature adjusted with a small screwdriver". Clockwise direction is for increasing value adjustment, and counterclockwise direction is for decreasing value adjustment.
Step 3: Press the power switch and compare the "temperature", "humidity" and "resistance" values. Press the power switch resistance again and observe the LCD display for the calibration measures of the resistance tester. Close the watch cover and tighten the four fixing screws. Press the power switch to determine whether the watch is working properly.
