DIGITAL Multifunction Voltage Tester
INTRODUCTION
This is an equipment used to test the automotive electrical system within 12-24 volts. In order to save
the testing hours for the automotive electrical system, it is designed to testing the system without re-
connection between the vehicle battery and the testing components.
FUNCTIONS
Determine the polarity and circuit circumstance (short/ open).
•
Activating the components with positive or negative current without jumper wire.
•
Testing the voltage and continuity of the circuit.
•
Illumination.
•
Locate missing cylinders.
•
Measuring frequency of the high-tension ignition pulses and we could calculate the rotational
•
speed of engine according to the measured frequency.
Peak detection.
•
Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display
•
within 1/10 of a volt.
WARNING
When current is provided to the unit, spark may be occurred when the tip contacts with ground or
•
certain circuits. Therefore please do not operate it around flammable.
Do not operating it with 110/220 volt house voltage as it is only for 12-24 volt system
•
Important: Read these instructions before using the device for the first time.
•
Be sure where you are testing, when applying positive and negative potential, components such
•
as Control module, potentiometer, etc. can be destroyed.
Manual transmissions always idle and automatic transmissions always insert "P". Faulty
•
measurements at the starter can be accidentally activated and can property damage and serious
injury.
Be careful when using the extended test tip, short circuit risk, because they are not isolated.
