How to use pliers table check fault

How to use pliers table checking fault - 2019 03 - 30 15:05:40 with clamp table check fault simple way is to put the table to sign like a & other; Month & throughout; Word inside a horizontal there less, if the short circuit, will di call, if don't have the short can't sound. And can call the watch on resistance, if the short circuit, can have resistance to the above, if there is no short circuit is 1. Clip-on ammeter is by the current clamp table a mix of iron core transformer and current meter. Current transformer iron core can open when pinched wrench; By measuring electric current through the wire can not cut off the can core open gap, when the iron core is closed after let go of the wrench. Through the core of the circuit under test wire becomes a coil current transformer, which through the current induced in the secondary coil current. So that the secondary coil connected to the ammeter has instruction - - - - Measure the current clamp table core of circuit under test. Clip-on table can be switch gear, a change in different range. But charged when not allowed to dial the shift. Clip-on table general accuracy is not high, usually is 2. 5 ~ 5 level. In order to use convenient, table and different range switch is used for measuring current and measuring voltage of different levels of functionality.
