Versatile and simple-to-use digital multimeters safely measure common ranges of voltage, current, and resistance, and are packaged in a very convenient compact size. They feature diode testing, continuity check with audible buzzer, a measurement rate of 2 readings per second, overrange and low-battery indication, and auto power-off.

Basic model 20250-50 offers manual ranging and measures AC and DC voltage to 600 V, resistance with continuity and diode function, and DC current to 10 A. Plus a dedicated battery test function lets you check the quality of your 9 V and 1.5 V batteries.

Full-featured model 20250-51 also measures AC current to 10 A, capacitance, frequency, duty cycle, and temperature via a type K thermocouple probe. An autoranging feature automatically selects the optimal measuring range for maximum resolution. Plus you’ll work more efficiently with the data HOLD and relative functions.

This model comes with two fuses (0.5 A / 250 V and 10 A / 250 V) for the probe terminals to prevent any injury, in the event of an overload, to the user or damage to the circuits. Another important feature is the continuity test. Setting the multimeter to the continuity test function, and latching together the probe’s tips, it produces an audible and solid tone with a good response time.

AC voltage measurement: No autoranging at 400 mV
