Digital multimeter although measure current, current, resistance, capacitors, transistors along with other fundamental parameters, but additionally with the alternative use can expand the functions from it, make itself right into a multi-function meter.
Today, I will introduce a means of methods to look for the breakpoint from the wire or cable.
When there some breaks with wire or cable, because the exterior package from the wire or cable have insulations, so to look for the exact place from the breakpoint is extremely hard. We are able to use digital multimeter to assist us solve the issue. The particular techniques are as follow: put one for reds from the wire or cable which has a breakpoint attached to the firing type of 220V, and set sleep issues floating in mid-air. We are able to set the digital multimeter within the AC-2V profile, in the access side of firing line to began, one hands hang on the purpose of the black meter pen, another hands contain the red-colored meter pen move ahead the exterior insulation from the wire or cable's package, this time around, the need for current shows about .445V. When the red-colored meter pen move onto somewhere that the current is all of a sudden dropped to . a couple of volts which display on screen, therefore we can certain the position of the breakpoint is forward 15cm across the access side which around the firing line.
If use by doing this to check on shield, it'll no use in cases like this that's only wire damaged and shield package isn't damaged.
