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.
