V200Pro Circuit Tester
VDIAGTOOL V200Pro is a professional automotive circuit testing tool that combines circuit data monitoring and fault location functions, helping technicians quickly diagnose and solve automotive electrical system problems.
Dual Mode Operation
Mode 1️⃣: Circuit Data Value Monitoring - Measures whether circuit component parameters are within reasonable range
Mode 2️⃣: Circuit Problem Location - Precisely locates fault points through audible alarms
Applicable Models
Cars, SUVs, minivans, trucks, tractors, boats, and RVs
Voltage Range
6-42V DC Voltage
Dual Mode Working Principles
V200Pro provides two professional working modes to meet different circuit testing needs
- DC Voltage Measurement: Reads DC voltage with 0.1V resolution
- AC Voltage Measurement: Reads maximum voltage, minimum voltage, frequency and duty cycle
- Resistance Measurement: Reads resistance between probe and auxiliary ground wire
- Diode Measurement: Reads diode resistance value to determine if it is damaged
- Short Circuit Location: Locates short circuit position when fuses blow frequently
- Open Circuit Detection: Detects open connections and broken wires
- Current Leakage: Detects current leakage through tone changes
- Non-destructive Testing: Trace wires/cables without damaging the insulation
Note: Mode 2 requires 1 piece of 9V battery for power supply
Product Core Features
Innovative design and technical advantages of VDIAGTOOL V200Pro
Component Activation Function
By supplying current to directly contact the component to generate an activation signal, test lights, motors, wipers, radiator fans, relays, and various sensors to determine if the component is in good condition.
DC/AC Volt Measure
① DC Voltage Test
Detects the voltage value of the circuit
with a resolution of 0.1volt.
② AC Voltage Test
Detects the Max Voltage,Min.Voltage
and Frequency of the circuit.
Resistance Measure
Detect the resistance between the circuit
probe tip and auxiliary ground lead,
determines whether an electrical circuit is complete or broken and if the resistance of a component matches the
manufacturer's specification.
Overload Protection
Built-in short circuit protection function, automatically shuts down and restarts when overloaded to protect the device and vehicle electronics. This function can also be used to conveniently test for short circuits.
Located Open Break Wire(Mode 2)
Open Circuit problem localization. Accurate indication of fault points through audible alarms to assist in repairs
Diode Test
Detect the operation of the diode assembly
ortheactualforwardvoltageand
determineif it is conducting.
Product Appearances Design
Dual Charging Modes
Can be powered by car battery or cigarette lighter, no additional batteries or cables needed, more flexible and convenient to use.
One-key Dual Mode Switching
One-key switch between power circuit probe tester function mode and circuit breaker finder tool mode, no additional tools needed to determine cable/wire continuity and diagnose circuit breaker points.
Dual Headlights & LCD Display
Equipped with dual LED lights for low-light environments. High-definition LCD digital backlit display for clear reading day and night.
20ft Extension Cable
Comes with 20ft long cable and 20ft extension cable, can be powered via cigarette lighter, with alligator clips for easy grounding, allowing testing of circuit systems anywhere around the vehicle.
Quick Self-test
Quick self test to make sure it is working properly before you start using it.
Press the power switch forward to activate the tip with a positive voltage. The red LED lights up and display the battery voltage.
Press the power switch backwards to activate the tip with a negative voltage, the green LED should light up and the display will read 0.0V.
User Guide
Quick Start with V200Pro Circuit Tester
Prepare the Device
Take out the adapter cable to connect the device and the vehicle to power the device. Adapter cable connects to probe device at one end, with red and black clips at the other end.
Mode 1 Operation
Connect small clip to probe device and touch detection location. Start probe for testing. Freely switch between four detection modes.
Mode 2 Operation
Toggle switch to turn off probe screen (requires adding battery). Press and hold start button, probe along wiring. When clear audio alert sounds, that area is identified as circuit breaker.
Overload Protection
Sudden black screen or restart indicates overload (short circuit) at current position. Device has overload protection and will restart shortly for continued testing.
Volume Adjustment
Device self-tests with sound at startup. Adjust volume using right rotary button to suit different work environments.
Switch Operation
When starting probe test kit, first press power switch, then touch component with probe. This extends power switch lifespan.
