Fits portable four-terminal low-resistance testing where you need an Extech 380580 covering 200.0 mΩ to 2000 Ω with 0.1 mΩ resolution and over-temperature/over-voltage protection.
Key advantages
- Ranges — 200.0 mΩ, 2000 mΩ, 20.00 Ω, 200.0 Ω, 2000 Ω
- Resolution / accuracy — 0.1 mΩ max; ±(0.5% reading + 2 digits)
- Method — Four-terminal Kelvin
- Test current — 100 mA / 10 mA / 1 mA (range dependent)
- Protection — Over-temperature and over-voltage; Auto-Hold; 8× AA
Typical applications
- Bond and contact resistance.
- Field milliohm checks.
- Protected Kelvin testing with invalid-test indicators.
Selection guide
- Lowest range — 200 mΩ / 0.1 mΩ needs
- Kelvin leads — Lead set condition
- Power — 8× AA
- Protection — OT/OV indicators
Common mistakes
- 2-wire measurements including lead resistance.
- Wrong range/test current for DUT.
- Ignoring over-temp indicators.
