PowerScan PS100 Automotive Circuit Tester 2.0, 12-24V Power Circuit Probe Tool, Electrical Short Open Circuit Finder, AC/DC/Resistance/Component/Signal/Test Light Automotive, 20ft Extension Cord

4 Advanced ModesQuick& Accurate4 modes via Mode Button. Just Contact probe to circuit, LCD
instantly displays results: 1DC
voltage: read the DC voltage with a resolution of 0.1 volts. 2AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle, shows the modulation from the ECM to an Alternator wire to see if the ecm is commanding the alternator on. 3Resistance: read the resistance between the tip and auxiliary ground lead, you can clearly check fuse/line continuity, pinpoint open circuits & verify switch functions. 4Tone
On/Off: it can indicate the tester's on/off status, You can turn it off to avoid ear interference from noise during testing.
Pro Continuity Tester & Signal Circuit TesterPS100 easily locates wire breaks and checks ground quality. 1
Resistance Mode: Connect the probe tip and ground lead. A solid connection reads 0.0 with a green LED. OL means an open circuit. You can even pierce insulation to test without disconnecting wires. 2
Power Switch Method: Applies voltage to check for ultra-low resistancegreat for ground tests. What to do when faced with reading a DTC to learn that a sensor may have a problem?
Signal Test: In AC mode, connect to the sensors signal wire and ground. As you operate the sensor, view live Max/Min voltage, frequency, and duty cycle on the LCD to confirm proper function.
Short Circuit Troubleshooting & Built-In Overload ProtectionAs a good relay tester, the PS100s resettable circuit breaker helps quickly locate short circuitsjust apply voltage along the line using its highly sensitive probes to pinpoint the issue, saving both fuses and money A built-in 10 Amp breaker also protects against overloads, cutting power and sounding a buzzer if limits are exceeded. The circuit breaker will trip if it becomes overloaded to protect the battery and give a buzzer warning. When the circuit breaker is tripped, the Electrical Probe Tester will NOT be able to conduct battery current to the tip even when the power switch is presseduntil it resets.
Quickly Identify Polarity & Highly Sensitive Probe PS100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative and open circuits. When the positive terminal is connected, the red LED test light is on, accompanied by a beep. When the negative terminal is connected, the green LED is on, along with low pitched tone. If it is an open circuit, the LED light will not light. By using red/green LEDs (illuminated only within ± 0.8V ) alongside the LCD reading, the PS100 provides quick voltage drop detectionturning a simple polarity check into a reliable diagnostic tool. The sharp stainless steel probe easily pierces wires and reaches tight areas.
