The meter can be used for demonstration of A.C or D.C. ammeter or voltmeter with different interchangeable scales. A magnetically damped, spring-controlled moving coil movement with a pointer, housed in a plastic case with glass front and rear panels enable all working parts to be clearly seen. With a pair of 4mm socket terminals and side zero adjustment control. The scales, 200mm long (approx.) are boldly marked and figured on both sides. Each scale is fitted through a slot in the side of the case and has a plug connector which also serves to locate and align the scale positively in position. Basic sensitivity of the meter is 5mA, 100mV F.S.D. Without scale. Accuracy: ? 2.5%, F.S.D., Scales: | | Range D.C.
