The picture suggests 10ma, will it read to .001A?** A: Hi, Yes, the lowest current it will read is 0.01A (10mA), and it can not read to 0.001A ( 1mA). The resolution will be 0.01A when the testing current less than 10A. The resolution will be 0.1A when the testing current less than 100A. **Q: Can I use this instrument with 4 feet of wire between meter and current sensor transformer?** A: I use mine with a line cord attached the measure voltage and frequency of my standby generator and it works quiet well. My line cord iw over 4' Good Luck **Q: Does this allow for 220 volt input with 2 110 volt wires** A: Yes it measure up to 300 volts and will measure 2 lines of 110 volts if they are different phases just like the 220 in your home. **Q: One spec says 0-50A another says 0-100A. Can this device continuously monitor 70 amp at 110 volts?** A: Hi, I am sorry for that these two different description make you confused, since the listing had been locked by amazon, and we can't revise it. Here we confirm that Its measurement range is 0-100A, 80-300V, AC. So it can continuously monitor 70 amp at 110 volts, AC. ## Frequently Bought Together - KETOTEK Digital AC Voltmeter Panel Mounting Meter AC80-300V Frequency Counter 45.0-65.0 HZ LED Display Voltage Volt Frequency Meter Tester Gauge - Ogrmar Plastic Dustproof IP65 Junction Box DIY Case Enclosure (3.9"x 2.8"x 1.6") - DaierTek 30A 250V KCD2 KCD4 Rocker Switch DPST 4 Pin Red Lighted 120V Rocker Toggle Switch ON Off Heavy Duty T125-3Pack --- ## 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.com.pa/products/27807565-ketotek-digital-ac-voltmeter-panel-mounting-meter-ac80-300v-frequency](https://www.desertcart.com.pa/products/27807565-ketotek-digital-ac-voltmeter-panel-mounting-meter-ac80-300v-frequency) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-06-12*
