General Radio 1602B Impedance Measuring System

Description

RANGE: Theoretically, zero to infinity; practically, the lower limit is determined
by the smallest readable increment on the scale, which is 100 micromhos
(0.1 millimho). The upper limit is 1000 millimhos. Range is the same
for both conductance and susceptance, but susceptance can be either positive
or negative, i.e., the susceptance dial is calibrated from -20 to +20
mi II imhos. Multiplying factors from 1 to 20 are provided, and factors from 20
to 100 can be determined approximately.
