INTRODUCTION
The RCL-bridge PM 6302 is used to measure ohmic resistors in the range 0.05 Q ... 105-MQ, capacitors in the
range 0.5 pF .... 1050 uF and inductances in the range 0.5 42H ... 1050 H. When measuring capacitors and
inductances also a measuring value of the loss factor D or the quality factor Q is obtained.
For the adjusting a vernier with linear indicator scate is used. The unknown measuring value is obtained after
the adjusting by multiplying the scale value by the factor of the selected measuring range.
The bridge balance is indicated by a moving-coil indicator, which is controlled by an amplifier with
logarithmic gain characteristic, adjusting of the bridge sensitivity being then redundant.
Push-button SEARCH
is used to find quickly the correct measuring range in the searching mode,
For measuring electrolytic capacitors an external formation voltage can be supplied.

By means of an external adjustable d.c.-voltage it is possible to measure junction-capacitances on varicaps.
