What are the preparations for the cable fault detector before use? When the cable fails, we need to use the cable fault detector to detect the cable fault. In order to ensure the normal use of the cable fault detector, what preparations do we usually have to do before the cable fault detector is used? When the cable fails, we need to use the cable fault detector to detect the cable fault. In order to ensure the normal use of the cable fault detector, we usually have to do some preparations before the cable fault detector is used. Today Let's take a look at what to do before using the cable fault detector. 1. Choose a suitable cable fault detector Because there are many types of cable faults, the detection methods of cable faults corresponding to different types of cable faults are also different, so for different types of cable faults, we need to choose different cable fault detection methods instrument. 2. Check whether the cable fault detector is damaged. Before using the cable fault detector, we should turn on the cable fault detector to see if the cable fault detector can still be used normally. If it cannot be started normally, we can also detect the cable fault. If it still doesn't work, then we have to choose another cable fault detector.
3. Test whether the multiple meter heads of the cable fault detector are sensitive to zero. The frequent use of the cable fault detector may cause the pointer of the cable fault detector to be unable to zero, or the cable fault detector is not used for a long time. The sensitivity of the head pointer is not enough. These situations will lead to very serious consequences when we use the cable fault detector to detect.
