Zener Diode Characterisitcs Apparatus

Zener Diode Characterisitcs Apparatus has been designed to study Forward and Reverse Bias Characterisitcs of a Zener Diode.
The instrument comprises if the following built in parts:

1. One continuously variable DC Regulated Power Supply of 0-15V with output brought out at 4mm sockets.
2. Two meters to measure voltage & current are mounted on the front panel & connections brought out at 4mm sockets / terminals.
3. One series Resistance & three Zener Diodes (3.3, 6.2, 9.1V) has been provided on the front panel with connections brought out at 4mm sockets.
