Intended for heavy-duty use, the 500 Series of industrial multimeters is waterproof to IP67 standards and drop-proof to up to 6 ft. All three models in the series carry a safety rating of CAT IV 600 V and CAT III 1000 V. Each meter measures voltage, resistance, electrical and electronic frequency functions, and DC/AC current. In addition, units feature 1000-V input protection for all functions, dual-sensitivity frequency functions, and diode open circuit voltage of 2.8 VDC. Other features include true RMS measurements with capacitance and Type-K temperature, peak hold, 6000-count LCDs on the EX510 and EX520, and a 44,000-count LCD on the EX520.
