12V 24V Truck/Car Circuit Tester Electrical Diagnostic Tool Power Probe Kits

  

Ancel PB500 Automotive Power Circuit Probe Tester Inspection Tools 12V 24V Electrical System Mechanical Fuel Injector Test Frequency Duty Cycle Test. PB500 Has 7 Test Modes.

DC Voltage, AC Voltage, Frequency, Duty Cycle, Fuel Injection Circuit Detection, Resistance, and Diode. Especially, in AC Voltage, Frequency, Duty Cycle and Fuel Inject Modes, user can long press the mode button to switch between Waveform Display Mode and Digital Display Mode. After the power is turned on, short press the mode button to enter the menu, select the test mode by pressing the up and down keys, and then press the mode button to enter the desired test mode.

ANCEL PB500 Electrical System Circuit Tester Functions. Diagnose 12 24V automotive electrical systems swiftly and accurately. Show battery voltage reading and help user determine circuit polarity immediately after connecting the PB500 clips to the vehicle battery. Test DC Voltage, AC Voltage, Frequency, Duty Cycle, Fuel Injection Circuit, Resistance, and Diode.

Especially, in AC Voltage, Frequency, Duty Cycle and Fuel Inject Modes, user can long press the mode button for 3 seconds to switch between Waveform Display Mode and Digital Display Mode. Activate electrical components and test their functions without jumper leads - by depressing the rocker switch to conduct a positive or negative battery current to the tip so as to power up electrical components.

Test bad ground contacts instantly without performing voltage drop tests. Help user to follow and locate short circuits without using external fuses. Test continuity with the assistance of its auxiliary ground lead.

The tool is short-circuit protected. If it becomes overloaded, Its internal circuit breaker will trip to protect the instrument from overload. When the circuit breaker is tripped, the tool will NOT be able to conduct battery current to the tip even when the rocker switch is pressed; however, all other functions of the tool are still active, which means you can still probe a circuit and observe the voltage reading. Crochet Hook Extension Cable x1. Rugged Blow Molded Case x1.

Before testing a circuit or component, make sure your tool is in good order by doing a quick self-test. Connect the vehicle battery properly to turn the instrument on, the instrument enters DC Voltage Mode by default, and the fast self-test is performed in DC Voltage Mode. The rocker switch is an on-off switch located on the tool's front side. The positive and negative poles are marked above and below the switch.

Press the Rocker Switch forward to activate the tip with a positive voltage. The Red LED should light and LCD display will read the battery voltage and tip voltage. A beep tone will sound.

Let go of the rocker switch and the LED will turn off and the tone will cease. Press the Rocker Switch rearward to activate the tip with a negative voltage. The Green LED should light and the LCD display will read the battery voltage and 0.0V (ground). Your tool is working correctly and is now ready for use. Ancel PB500 is ONLY for 12-24V vehicle battery electrical systems, and should NOT be used to test 110/220V household electric appliances; otherwise, it will be damaged. The LED and LCD pull no more than 100 milliamp of current, therefore when using this device as a test light or multimeter, it is safe for computer and airbag. While performing component activation, please pay special attention: when the instrument is powered on, if the rocker switch is pressed forward or rearward, it means that all the battery current is being introduced from the positive or negative pole through the probe. Please strictly follow the instructions to avoid damage to the vehicle's electrical component.
