MS ANALOG INSTRUMENTS FOR ELECTRIC MEASUREMENTS INTRODUCTION These precision instruments (accuracy rating of 0.5) have been designed to be used in electrical engineering laboratories. Losses and response times of movable components are minimized, thus these apparatuses are light and damped, shockproof and vibrationproof. ELECTRICAL ENGINEERING The cases of these instruments are of shockproof thermosetting material. Scales are plotted with a high number of divisions; a lot of instruments have various scales to avoid the adoption of non integer or inconvenient constants. Electromagnetic (or moving iron) instruments are shielded against external magnetic fields and they have not any hysteresis; they can be used in both DC and AC always complying with the limits of accuracy rating. Here are the available instruments: • Ammeters • Voltmeters • Wattmeters • Cosphimeters • Frequency meters • Galvanometers • Ammeter transformers • Shunters INSTRUMENTS FOR IMPLEMENTING THE EXPERIMENTAL PROGRAMS OF ELECTRIC MEASUREMENTS AND MACHINES (Magneto-electric) MOVING COIL AMMETER mod.
