Ancel PB50 Car Circuit Tester Inspection Tool Automotive Power Circuit Probe Kit 12V 24V Electrical System Mechanical Works Tool

Auto Circuit Breaker
The tool is short-circuit protected. Its internal circuit breaker will trip if it becomes overload. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload.

When circuit breaker tripped, all other functions of the tool are still active, which means you can still probe a circuit and observe the voltage reading. When the circuit breaker is tripped, the tool will NOT be able to conduct battery current to the tip even when the power switch is pressed. Intentionally tripping the breaker and using the tool to probe can be considered an added precaution against accidental pressing of the power switch.

 Work mode
There are four modes to diagnose the electrical systems, which can be accessed by depressing the Mode Button and cycling through each one.

DC voltage 
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the DC voltage with a resolution of 0.1 volt. 

AC voltage 
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the Max. voltage, the Min. Voltage and frequency.

Resistance test
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.

Diode 
In this mode, the probe tip contact the positive terminal of the diode, connect the auxiliary ground lead to the negative terminal of the diode, the screen will display the forward voltage drop, indicates the forward bias. If exchange the probe tip and auxiliary ground lead, the screen will not display the voltage, indicates the reverse bias.

Voltage & Polarity Testing 
While the tool is in DC Voltage mode, contact the probe tip to a POSITIVE circuit. The red LED will light and the LCD displays the voltage with a resolution of 0.1V. A beep tone will sound.
If contact the probe tip to a NEGATIVE circuit, the green LED will light and the LCD displays the voltage with a resolution of 0.1V. A beep tone will sound.
If contact the probe tip to an OPEN circuit, neither of the LED will light.

 Continuity Testing 
While the tool is in Resistance mode, using the probe tip with chass is ground or the auxiliary ground lead, continuity can be tested on wires and components attached or disconnected from the vehicle’s electrical system. 
When the probe tip is contacting a good ground, the LCD will indicate “0.0Ω” and green LED will be on. A beep tone will sound .  In other cases, the LCD only indicates the resistance value. 
If the resistance value is greater than 100KΩ, the LCD will show “0L”. 
There is also another way to prove continuity of connections to ground or battery. Power up the connection using the power switch. If the circuit breaker trips you know that you have a good solid low resistance connection.
