Voltage Test - BGS technic 40105 Manual De Instrucciones

ACTIVATE THE COMPONENTS WITH NEGATIVE VOLTAGE ONLY
Apart from applying the positive voltage, technician can also use
this unit to provide negative voltage to the components. The
procedures are as follow:
1. Contact its tip to the negative pole of the component; at this
stage, the red LED should be on if the component working
correctly.
2. Push the polar switch backward and release it quickly. If the
LED goes from red to green, you may proceed further test. If
the green LED goes off or the circuit breaker of the short
circuit protection tripped, it means it has overloaded. This
may cause by the following reasons:
1. The component is short circuit or it has been connected
to the ground/ negative pole directly.
2. The component is a high current component.
If the circuit breaker of the short circuit protection has tripped, it
will auto-rest within no more than 60
IMPORTANT

Please operate this function with schematic and correct testing procedure because applying voltage
arbitrarily may cause damage to components. Use tip to apply negative voltage, which can be helpful
to diagnose the components.

When applying current to the components, please push the switch before contact the tip with the
components. In this case, the arcing will take place between the tip and the component instead of the
switch. And so it can increase the life time of the switch.
TRAILER LIGHT TEST
To test the trailer light, you need to follow the procedure:
1. Connect the ground test lead to trailer ground.
2. Probe the tip to the outlet of the trailer; push the polar switch
forward, then technician can diagnose the function of the
trailer light.

VOLTAGE TEST

Technician can also use this unit assisting with ground test lead to test the voltage of the circuit. However,
during the voltage test, please do not push the polar switch.
1. If probe tip is floating (not contacting a circuit), the red and green LED turn off.
2. If it contact the probe tip to a positive circuit. The red positive sign "+" LED will light and the voltmeter
displays the voltage reading within 1/10 of a volt.
3. If it contact the probe tip to a negative circuit. The green negative sign "-" LED will light.
