How To Use Multiple Dc Ammeters To Measure A Load Current In Line Fittings?
Insulation Piercing Connector How to use multiple DC ammeters to measure a load current?
When you need to observe the load current at multiple locations, you can use multiple DC ammeters to measure the current of a load. The ammeters used in this connection method must have the same model and range, so that the readings of each meter are the same. The ammeters used must be connected in series, and the polarity cannot be reversed. In that case, if the ammeter is connected in parallel to current B, the pointer will bend or even burn and damage the power supply (because the internal resistance of the ammeter is very small, it is equivalent to short-circuiting B). Ammeters are usually installed on the panel of the distribution board, distribution cabinet or instrument box.
