This compact digital multimeter measures only 4.25 x 2.2 x 0.5 and weighs a mere 3 ounces.The PM3 is designed for measuring low voltage circuits and is compliant with the EN61010-1 CAT.II 500V safety standard.The PM3 digital multimeter can perform all basic measurements such as voltage, resistance, capacitance, frequency, and duty cycle as well as continuity test. The probes in the Sanwa PM3 are internally connected with the circuit and cannot be removed unlike in a standard size multimeter.The device is EN61010-1 CAT.II 500V compliant, meaning it can be used to measure the main socket and plug-in loads such as home electrical appliances. For keeping the device protected against moisture and dust, the PM3 comes with a leather case that holds both the multimeter and test leads in place.
