Information

The RCL-bridge PM 6302 is used to measure ohmic resistors in the range 0.05 £1... 105 Mfi, capacitors in the range 0.5 pF ... 1050 fxF and inductances in the range 0.5 /jH ... 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 scale 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-buuon 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.
