If not, the answer to this question will vary depending on which voltage setting you use and the resistance of the system you are testing. If for example, you test using the 1000v setting on a cable that has 2G-OHM resistance, the current is 1000 / 2,000,000,000 = .5 uA. **Q: Can it measure polarization index measurement (pi) and dielectric absorption ratio measurement (dar)?** A: Yes, Both require a megaohmmeter, You just have to follow the correct sequence /procedure ## Frequently Bought Together - BTMETER BT-6688B Megohmmeter 200 Gig Ohm Digital Insulation Resistance Tester, 500V/1kV/2.5kV/5kV Test Voltage, Auto Ranging, Backlight Display - Klein Tools ET600 Multimeter, Megohmmeter Insulation Tester, 4000 Ohms Resistance, 125V/250V/500V/1000V, Auto-Ranging TRMS Multimeter - ATOPLEE 3 Phase Sequence Presence Rotation Tester Indicator Detector Meter with LED and Buzzer 60V~600V (3 Phase AC) --- ## 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.gr/products/66364272-btmeter-bt-6688b-megohmmeter-200-gig-ohm-digital-insulation-resistance](https://www.desertcart.gr/products/66364272-btmeter-bt-6688b-megohmmeter-200-gig-ohm-digital-insulation-resistance) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-17*
