1. GENERAL
Precision Wheatstone Bridge 2768 is an instrument designed for measuring DC resistance from
0.1 Ω to 110 MΩ.
This instrument is equipped with a galvanometer and a power source internally,
and the measured value is indicated in-line indication without using any additional equipment externally.
Moreover, this instrument is designed with maximum care for the precision and stability of
resistance elements and also for the insulation of the measuring circuit, and is provided with
a guard terminal and a ground terminal.
Therefore the precision measurement is accomplished with 2768.
