Fits general-purpose True RMS metering where you need an Extech EX430A with ±0.3% basic VDC accuracy, capacitance/frequency, Type K temperature, and a large backlit display.
Key advantages
- Accuracy — Basic VDC ±0.3%; True RMS AC
- Ranges — V to 600 V; A to 10 A; Ω to 40 MΩ; capacitance to 100 µF; frequency to 10 MHz
- Temperature — Type K −4 to 1382 °F (−20 to 750 °C)
- Functions — Autoranging; relative; diode; continuity; duty cycle
- Safety — CAT III rated; input fuse protection; 9 V battery
Typical applications
- True RMS troubleshooting on non-sinusoidal loads.
- Capacitance and frequency checks.
- Field kits needing Type K temperature.
Selection guide
- True RMS need — Prefer EX430A over average-responding models
- Temperature range — Type K span
- Form factor — 7.4 × 3.2 × 2 in; 0.75 lb
- Warranty — 3 years class
Common mistakes
- Confusing with heavy-duty IP67 EX520A.
- Exceeding 600 V CAT III limits.
- Wrong Type K probe temperature class.
