On a scope, with the meter open circuit, the test waveform is a rounded square wave. When connected to a 100 ohm resistor, the waveform is more of a triangle wave. When connected to a capacitor, it is somewhere between a triangle and a sine wave. **Q: can this meter perform a leak test on motor start capacitors?** A: No. This meter is for one test only - ESR of a capacitor. It does not perform any other tests. **Q: Values in 35v and higher columns decrease as you go down, columns for 10,16,25v decrease, then go back up. is this a typo? hint: look for ".12"** A: Better to use on of the ESR charts you can find online, not the one printed on the case (whether it's right or wrong) **Q: what is better about v2 (version 2) of this MESR-100 meter for the extra $10 it costs over the original version?** A: Compare MESR100 old V1 and new V2 Improvement: For an extra $10 I would get version 2 which is what I have now. 1) Change square wave to sine wave 100 KHz, reduce square wave’s high frequency component, and affect the reading passing the test leads and capacitor. 2) Higher Resolution up to 0.001 ohm. 3) 128X64 dot matrix LCD, with more larger value display and information 4) Embedded 25V capacitor table at LCD, auto display the capacitor is good or bad reference to common 25V electrolytic capacitor. 5) New plastic case, curve design for hand carrying. New stand for 60 degree stand on desk. 6) Use 2X AA battery, more convenience and longer battery life than 9V battery. 7) Support external USB power, using standard micro-USB port. ## Frequently Bought Together - Signstek MESR-100 V2 Auto Ranging in Circuit ESR Meter Capacitor Tester/Low Ohm Meter Up to 0.01 to 100R, Support in Measuring Capacitance Resistance Circuit - Lesnow solder wick braid 10ft Length Desoldering Wick Braid Remover Tool Solder Sucker 1 piece No-Clean soldering Wick Wire Roll and Disassemble Electrical Components - YIHUA 929D-V Electric Desoldering Soldering Iron Solder Sucker Desoldering Pump with Shorter Charging Handle and Desoldering Nozzles 1.0mm 1.2mm for Through-Hole Desoldering --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/4478349-signstek-mesr-100-v2-esr-meter-capacitor-tester-low-ohm](https://www.desertcart.sg/products/4478349-signstek-mesr-100-v2-esr-meter-capacitor-tester-low-ohm) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-12*
