object:
to measure the value of unknown self inductance by owen's bridge
feature:

01. Owen's bridge circuit with arm values
02. ±15v dc at 100 ma, ic regulated power supply internally connected. 
03. 1 khz sinewave oscillator output 0 - 15 vpp. 
04. Audio amplifier and speaker for null detection. 
05. Three unknown value of inductor selectable by a band switch. 

06. Potentiometer 1k - 10 turn for selecting desired resistance value. 
07. Potentiometer for balancing the bridge. 
08. Adequate no. Of electronic components. 
09. Mains on/off switch, fuse & jewel light. 

* the unit is operative on 230v ±10% at 50hz ac mains. 
* adequate no. Of patch cords stackable 4mm spring loaded plug length 1/2 metre. 
* good quality, reliable terminal/sockets are provided at appropriate places on panel for connections/ observation of waveforms. 
* strongly supported by detailed operating instructions, giving details of object theory, design procedures, report suggestions and book
references.
