Precautions for using the multimeter
(1) Carefully read the instruction manual to understand the structure of each part of the digital multimeter, and master its various functions and parameter limits during use.
(2) Determine the measurement items before measurement, determine the measurement method, and select the appropriate range. When measuring an unknown voltage or current, first turn the rotary switch to the maximum range, and then select a suitable range after a test.
(3) Before each measurement, check whether the sockets of the red and black test leads are correct, whether they are in the required function position, and whether the selection of the measuring range is appropriate.
(4) During the measurement process, it is strictly forbidden to switch the function gear at will. If it is really necessary to switch the function gear, the two test leads should be removed before the operation. Similarly, after the measurement, the test leads should be removed first and then switched to the OFF position.
(5) When measuring, use one hand to hold the insulating part of the red and black test leads for operation
