The poor English is confusing but there are some diagrams that might help. Basically there are two procedures, which I will outline below:1. Measuring the Earth Voltage: (do this test first)Why do this? I think it's to check there are no interfering voltages in the ground you are testing.a. Setup the meter and leads as shown in the diagram on page 5.b. Then plug the E lead into the V socket on the meter.The setup now looks like the diagram on page 6.c. Set the switch to EARTH VOLTAGEd. Read the LCD display and make sure it's less than 10 volts.e. Set the switch to OFF.f. Plug the E lead back into the E socket on the meter.2. Measure the Earth Resistance: (do this test second)Why do this? To measure the resistance of the earth rod you've just installed.a. Setup the meter and leads as shown in the diagram on page 5.b. Set the meter switch to 2000 ohms.c. Prest the TEST button and take an EARTH RESISTANCE reading.d. If no reading then set the meter switch to 200 ohms.e. Press the TEST button and take an EARTH RESISTANCE reading.f. If no reading then set the meter switch to 20 ohms.g. Press the TEST button and take an EARTH RESISTANCE reading.The rest of the instructions (starting on page 6) and the diagram on page 7 show an alterative way of measuring the EARTH RESISTANCE if you can't connect the E lead directly to the Earth rod under test.I tested the meter using the normal procedure outlined above. After driving in an 8 foot earth rod into fairly hard ground I measured an EARTH VOLTAGE of 0.2V and an EARTH RESISANCE of between 125 and 178 ohms (depending on the soil conditions); anything under 200 ohms is acceptable. ## Frequently Bought Together - DUOYI DY4100 Digital Earth Ground Resistance Tester Meter - Brady Authentic (M21-750-499) Multi-Purpose Nylon Label for General ID, Wire Marking, and Lab, Black on White- Designed for M210, M210-LAB, M211, BMP21-PLUS and BMP21-LAB Printers, .75" W 16' L --- ## 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.vn/products/49019940-duoyi-dy4100-digital-earth-ground-resistance-tester-multimeter-resistance-measurer](https://www.desertcart.vn/products/49019940-duoyi-dy4100-digital-earth-ground-resistance-tester-multimeter-resistance-measurer) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
