ANCEL PB600 Automotive Circuit Tester – All-in-One Multimeter, Oscilloscope, Injector & Relay Tester for 12V/24V Vehicles
The ANCEL PB600 is a next-generation automotive circuit tester and diagnostic probe that combines the power of a multimeter, oscilloscope, injector tester, relay tester, and more—into one compact, easy-to-use tool. Whether you're a professional mechanic or a DIY auto enthusiast, the PB600 provides all the essential diagnostic functions you need to test, diagnose, and repair complex vehicle electrical systems efficiently and safely.

ANCEL PB600 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 KM50 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.

PB600 - Upgrade of PB500
PB600 has Fuel Injector Testing, Frequency Testing, Duty Cycle Testing, and Display Forms: Waveform. These are the features that PB100 does not have.

Multimeter & Oscilloscope Test Module
The PB600 acts as a fully functional multimeter with advanced oscilloscope capabilities. Measure:
-
DC/AC Voltage
-
Resistance (0~1MΩ)
-
Diode forward voltage
-
Current (AMP)
-
Frequency (0Hz–1MHz)
-
Duty Cycle (0–100%)
Its oscilloscope mode offers a waveform view of AC voltage, frequency, and duty cycle, helping diagnose issues related to sensors, actuators, and signal integrity in real time. All data is displayed on a 2.4-inch HD LCD screen (320×240 DPI) with intuitive layout and clear visual indicators.
ANCEL PB600 has 8 test modes:
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.
Instant Component Activation & Electrical Testing
The PB600 lets you apply power or ground directly to components using the probe tip. This makes it ideal for:
-
Activating lights, motors, fans, relays, injectors, and solenoids
-
Testing bad grounds, open/short circuits, and voltage drops without the need to dismantle wiring
-
Dynamic component testing without separate wiring or tools

2 Forms Display Mode
To switch Waveform Display Mode and Digital Display Mode. (In AC Voltage, Frequency, Duty Cycle and Fuel Inject Modes)


Fuel Injector Testing & Cleaning Function
Fuel injector maintenance is critical for modern engines. The PB600 can generate four pulse modes to test and clean injectors when combined with a standard fuel injector cleaner. This function allows you to:
-
Trigger injectors manually or automatically
-
Measure injection voltage (0–180V) and pulse time (0–25ms)
-
Switch between waveform and digital display modes for precision
Relay Testing Simplified
Avoid unexpected breakdowns caused by faulty relays. The PB600 includes a dedicated relay test module that works with standard 4-pin and 5-pin automotive relays, allowing you to verify relay operation with:
-
Relay test wires and auxiliary probes
-
Clear pass/fail indicators
-
On-the-spot component verification for headlights, fans, radios, and more
🔌 Smart Auto-Detection with Real-Time Feedback
Equipped with smart test functions, the PB600 automatically detects and displays:
-
Positive/negative polarity
-
Voltage/resistance levels
-
Continuity with audible buzzer
-
Waveforms for complex signals
No manual range selection is needed—just probe and go. The 20-foot cable lets you access hard-to-reach areas from the driver seat or rear of the vehicle with ease.
🔋 Comprehensive Battery Testing Module
The PB600 includes a complete 12V battery test suite for:
-
Battery Health Test
-
Cranking Test
-
Charging Test
With a rating range of 100–2000 CCA, it supports most vehicle batteries and helps you diagnose performance issues before they lead to failure.
