Objectives of this experiment: This demonstrator provides an insight into the working of an analog multimeter to the student. Selection of ranges made by patching wires is required for better understanding. Moving coil meter having a sensitivity of (0-200) mA has to be connected. This demonstrator provides an insight into the working of an analog multimeter to the student Selection of ranges is made by patch cords for better understanding. In this unit DC voltage ranges of 100mV, 1V, 10V, 100V are selected by using series resistors. AC Voltages are used, in the same ranges, by rectifying the input voltage before connecting to the appropriate series resistors. Meter protection is included to protect the meter against any accidental overloads, which will certainly burn the moving coil. Built in regulated power supply: 15V/500mA; + 1.5V/300mA
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
