. This medium-sized pocket multimeter is palm sized and offers basic but powerful functionality for measuring electrical voltages, currents, and resistances. It has a maximum DCV of 600V and 600O, ACV 20V~600V, and AC current of 20mA~10A. The range selector switch allows you to easily select between resistance, continuity, capacitance, temperature, diode test, transistor hFE, and data hold. This multimeter has a large LCD display which makes the readings easier to read and display. It also includes a low battery indicator, overload protection and an auto power off function. For extra safety, it also has an alarm that sounds if the potential is above the maximum voltage. This feature makes it ideal for use in confined spaces and in hazardous environments. The pocket structure makes it highly portable and it fits easily in a toolbox. It includes accessories such as a test leads set, battery, and a user manual. The UT33B also has a USB port to facilitate data exchange. It is a great choice for professional or hobby electronics technicians who want a reliable yet affordable digital multimeter.
