The ammeter and voltmeters are moving iron instruments with an accuracy class 2,5.
The externally adjustable red pointer of the ammeter enables quick comparison of measured with set values.
On ammeter for 1 A and 5 A CT connection a scale can be slid in from the side, thus enabling simple and quick local alignment.Zones 1 & 2
