          Auto  CirCuit  tester         

introduCtion

This circut tester is used to test automotive electrical 
systems from 12 to 24 volts. In order to save hours of 
testing the automotive electrical system, it is designed 
to test the system without re-connection between the 
vehicles battery and the testing components. It con-
tains the following functions:
•  Determine the polarity and circuit condition (short/ 

open).

•  Activating the components with positive or negative 

current without a jumper wire

•  Testing the voltage and continuity of the circuit.
•  Backlit digital display.
•  Locate misfiring cylinders.
•  Measuring frequency of the high-tension ignition 

pulses can also be used to calculate the rotational 
speed of engine according to the measured frequency.

•  Peak detection.
•  Testing the voltage of a circuit and displaying the 

voltage reading on the LCD display within 1/10 of a 
volt.

For testing and safety purposes, this unit contains 
short-circuit protection, which can also check the 
ground connection voltage drop tests. The short-
circuit protection system contains the auto reset circuit 

breaker so that the technician will not waste fuses 
during the testing. The extension cable with this unit is 
long enough for a technician to test the whole system 
of the vehicle. The technician does not have to con-
tinually search for a good ground connection.

iLLuminAtion

For testing in poorly lit or dark areas, the unit provides 
illumination for your convenience. The illumination will 
automatically be turned on as the technician connects 
it to vehicle battery.

imPortAnt

Please read the complete manual before you start to 
use this instrument.

Warning: risK oF deAtH

When current is provided to the unit a spark may  
occur when the tip contacts the ground or certain circuits. 
Therefore please do not operate it around flammable 
fluids or gases. Please do not operate it with 110/220 volt 
house voltage as it is only for 12 – 24 DC volt systems.
