51528 Inter Scale
Demonstration Meter
These meters can be used for demonstration and for actual
measurements.
A magnetically damped, spring-controlled moving coil movement in
a wood case 330 x 150 x 320 mm high with glass front and rear
panels to enable all working parts to be clearly seen. With a
pair of 4 mm socket terminals and a centre/side zero adjustment
control.
The scale, 200 mm long ( approx. ) are doldly marked and figured
on both sides so as to be clearly visible to the class from the
front and to the demonstrator from the rear. Each scale is
fitted through a slot in the side of the case and has a plug
connector which also serves to locate and allign the scale
positively in position.
Basic sensitivity of the meter is 5 milli-ampere f.s.d. The
meter can be used for demonstration of A.C. or D.C. ammeter or
voltmeter with the interchangeable scales. Without scales.
Accuracy : + 2.5% |
