PM Series digital multimeters offer superior user protection with UL safety ratings up to CAT III at 300V and CAT II at 600V, says the company. The units measure AC/DC voltage, frequency, capacitance, and resistance. Three models are available: PM51, PM53, and PM55. The PM53 and 55 have the AutoTectâ„¢ feature, which automatically adapts the meter to display volts or resistance modes.
