INTER SCALE ( DEMONSTRATION METER )

A MAGNETICALLY DAMPED , SPRING - CONTROLLED MOVING COIL MOVEMENT WITH A POINTER , 140 +/- 5 MM LONG HAVING A SPADE-SHAPED END IS HOUSED IN A WOODEN CASE 220 X 110 X 280 MM HIGH WITH GLASS FRONT AND REAR PANELS TO ENABLE ALL WORKING PARTS TO BE CLEARLY SEEN.WITH PAIR OF 4 MM SOCKET TERMINALS AND SIDE ZERO ADJUSTMENT CONTROL. THE SCALES, 130 MM LONG ARE BOLDLY 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 ALIGN THE SCALE POSITIVELY IN POSITION. BASIC SENSITIVITY OF THE METER IS 5 MILLI-AMPEAR f.s.d. THE METER CAN BE USED FOR DEMONSTRATION OF A.C. OR D.C. AMMETER OR VOLTMETER WITH THE INTERCHANGEABLE SCALES.

INTERSCALE DIALS : ALL INTERSCALE DIALS CARRY WITH THEM THE NECESSARY ACCESSORIES FOR CONVERTING THE METER TO THAT PARTICULAR RANGE OR FUNCTION.
