MESR100 M6013 ESR Capacitance Ohm Meter In Circuit Tester

Introducing the MESR100 M6013 ESR Capacitance Ohm Meter In Circuit Tester — a versatile, in-circuit tester designed for quick, accurate checks on capacitors and resistance in TVs, LCDs, audio boards, and other electronics. This dual-function instrument combines an ESR meter capable of true in-circuit testing with an advanced capacitance meter, helping you identify bad capacitors and insulate faulty components without unnecessary desoldering. The MESR-100 portion uses a true 100 kHz sine wave to measure ESR, effectively removing capacitor impedance and revealing the true series resistance. The M6013 portion expands your toolkit with a wide capacitance range and a bright, easy-to-read display, making it perfect for DIY enthusiasts and professional engineers alike.

Benefits & Tips

• In-circuit ESR testing lets you spot bad capacitors quickly in TV, LCD, and audio board repairs without removing parts.
• Dual-terminal design and a built-in reference ESR table speed up troubleshooting with fast, reliable results.
• Use the M6013’s large 128x64 dot matrix LCD and auto-averaging for stable readings on tiny pF to large mF values.
