Overview
This Operating Manual covers information on
safety and cautions. Please read the relevant
information carefully and observe all the Warnings
and Notes strictly.
In 1999 counts and 3-1/2 digits, the KN 8056 is a
manual testing automotive digital Multimeter.
Spotting a unique design with an extra large
screen, this meter has useful features such as a
fully-functional symbol display, connect prompt,
and full testing overload protection. For this reason,
it emerges as an electric multimeter with more
outstanding performance for safer operation than
other multimeters. In addition to the automotive
dwell and tach (rotation speed), this multimeter
can be used to test the AC voltage, DC voltage,
DC current, resistance, diode and continuity.
