Adopting the four‑terminal measuring method, this low‑resistance tester ensures ±(0.1%FS+20dgt) high‑precision reading. Equipped with pass‑fail comparison and data‑storage functions, it suits wire, motor winding and conductive‑joint resistance detection for factory‑site testing.
Measuring Principle: Four terminal methods
Measuring Current: ≤334mA
Open-Circuit Voltage: About 5V
Compare Functions: Directly Display PASS or FAlL Results Compared to the Preset Value
Data Storage: 99 Groups
Charged Prompt at the Tested end: ≤30V DC Waring
Auto Power Off: About 5 minute
Battery Level Alert: Divided into 3 Sections for Proportional Display
Zeroing Function
Back Light Function
Data Hold Function
