The LC Meter HM8018 offers a number of
features uncommon for an instrument of its
price range. Measured values are displayed on
a 3½ - digit LED with a basic accuracy of
0.5%. Measurements are performed at a 2
per second rate. Due to use of 3 oscillator
frequencies, which automatically switch upon
range selection, the instrument always opera-
tes at the optimum test frequency.
Besides L and C measurements, series and
parallel components of inductances and
capacitances can be determined with the
HM8018, providing easy evaluation of the
quality or dissipation factors of the com-

technique allows separation of real and imaginary
components up to a phase angle of 45° with
an accuracy of
resolution, 10mΩ Ω Ω Ω Ω / 0.01µS ensures precise and
reliable test results.
The accuracy and operability of the HM8018
make it ideal for use in virtually every area of
electronic technology, including quality control
and laboratory applications. The low number
of operating controls ensures that even non-
technical personnel can perform accurate
measurements after only brief instruction.
