Application: General purpose laboratory precision instrument whose inductance value can be varied from 1 mH to 10H, in steps of 1mH. Used in modern laboratories engaged in research, design and development of electronic circuits, filter networks, equialisers, tuned circuits, oscillators, frequency analysers, etc. in audio and low radio frequency regions, as a temporary substitution for finding optimum value of inductance. Four decade ranges are used; 1mH ?9mH, 10mH ?90mH, 100mH ?900mH and 1H ?9H. Can be used upto 10Mhz. Description: Uses four special decade switches. Ferrite cores of appropriate permeability and special winding techniques are used for minimum stray inductance and capacitance. Specifications: Accuracy : 2% at 1KHz Q : 25 to 150. Other Models: DIB-1 : 100 ?H to 99.9mH, in steps of 100 ?H - 3 dials DIB-2 : 1mH to 999 mH, in steps of 100 ?H - 3 dials DIB-3 : 100 ?H to 999.9 mH in steps of 100 ?H - 4 dials DIB-4 : 1mH to 9.999mH in steps of 1mH - 4 dials |
