ADVANCED FOURWIRE TECHNOLOGY Uses fourwire AC true sine wave measurement to significantly reduce errors caused by test leads and contact resistance, delivering precise and dependable readings for electrical evaluations and quality checks. EFFICIENT MANAGEMENT TOOLS Includes two functional interfaces and supports an easytouse sorting function to streamline testing workflows, making it a practical addition in workshops, labs, and field service environments. ENERGYEFFICIENT DESIGN Builtin mobile power charging functionality provides longlasting operation and minimizes the frequency of recharges during use, improving productivity in both field and bench settings. ACCURATE RESISTANCE TESTING Measures resistance up to 200 ohms with a resolution of 01 milliohms. The HOLD button activates the ZR function to measure very small resistances down to 0.30 milliohms with accuracy. USE SCENARIOS Battery testing: Assess internal resistance of lithium cells and packs to monitor health and performance without interference from lead resistance. Electrical assemblies: Verify lowresistance paths in connectors, wiring harnesses, PCBs, and power supplies to ensure reliable operation. Field and lab work: Leverage the builtin management tools to sort and record test results quickly, reducing workflow time and improving data consistency.
