What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.

What is ammeter selector switch?
A selector switch is normally used in a place to avoid 3 ammeters usage and instead measuring current in all the 3 phases using 1 ammeter only. Motto: SAVE MONEY.. :D The selector switch provided for ammeter is to check the amount of current taken from each phase supply. (ie) R,Y and B. Each phase supply should be covered with a current transformer with the rated amps capacities. The two leads of the the each phase CT are connected to the respective leads in the selector switch of the ammeter.
