Информация
The Distortion Analyser KM 6 is a multi-purpose instrument
for low frequency measurements in the laboratory, the
test line, for educational purposes and for use in
the hi-fi service department.
Designed for total harmonic distortion measurements in
the range 0.01% to 100% over a frequency spectrum of 10 Hz
to 100 kHz, the precision distortion factor meter is
equipped with a variable active Filter for the fundamental
frequency. The alignment to the 100% reference level
as well as frequency and balance alignment take place
semi-automatically. Rapid and accurate measurements
are ensured through 12 light-emitting diodes which
indicate the alignment conditions of the 100% reference
stage, the automatic frequency and balance circuit and
which also indicate the meter range selected. The
unit contains a sensitive AF-voltmeter for the voltage
range 300 m-V ... 300 V (f. s. d.). It can also be
used as a frequency meter over the range 10 Hz ... 100 kHz.
The unit is equipped with silicon semi-conductors
and integrated circuits. In addition to a standard
bench-top version with a tilting frame, the unit is
also available in a special version for mounting into
19 inch racks.
