Led Display Circuit Probe Tester

• Precision Current Measurement: Engineered for high-accuracy, real-time electrical current measurement in both residential and commercial vehicles, this tester reliably detects subtle current variations with exceptional fidelity
• All-Weather Operational Capability: Featuring a blue backlit LCD display, this instrument ensures clear and consistent readability of current data under varying ambient lighting conditions—from bright daylight to low-light environments—thereby minimizing the risk of overlooking subtle current variations. An integrated light illuminates provides targeted illumination of the test area during nighttime or low-visibility maintenance, enabling accurate and efficient circuit diagnostics in darkness
• Robust Construction: Constructed from impact- and abrasion-resistant ABS/PC polymer with an rubber coating, this instrument delivers exceptional durability and long-term operational reliability. Its ingress protection rating ensures resistance to incidental liquid exposure, including spills and ambient moisture, supporting dependable performance in demanding workshop or outdoor environments
• User-friendly operation procedure: (1) Turn off the vehicle ignition and and remove the blade-type fuse from the vehicle’s fuse box; (2) Disconnect the vehicle’s corresponding circuit fuse; (3) Insert the tester’s safety plug into the designated wiring harness socket; (4) Verify that the circuit protection device is properly installed and functional; and (5) Finally, insert the safety plug into the vehicle’s fuse socket—ensuring compliance with the rated maximum load of 20 A at 48 V DC
• Notice: The tester must not be operated beyond its maximum rated load: 20 A at 48 V DC for a maximum duration of 10 seconds; Prior to connecting or disconnecting the tester, ensure the vehicle’s ignition switch is fully turned off; This device does not include an battery
