Whether it's a digital table or a pointer table, the usage is the same. To measure whether a wire is good, we actually use a multimeter to measure its resistance value. If the resistance value is infinite, it means it is broken. A resistance value close to 0 is good. The simple use of a multimeter is to first set it to the Ohm range (measuring wire, any range is acceptable), then short circuit the red and black lines. The digital meter should be 0, and the pointer of the pointer meter should be biased to the right. (Zero adjustment is not allowed here) Then measure the line segment that you need to measure. The reading that appears close to the short red and black lines should be a path, which is good. Conversely, it is broken.
