The DT4255 is a digital multimeter designed for maximum safety with voltage measurement terminals that are protected by a fuse.
When using the resistance measurement function, a protective circuit functions to prevent a short-circuit accident in the event of erroneous operation such improperly supplying voltage input. Even if a short-circuit occurs inside the tester, a current-limiting resistor will limit any short-circuit current while a fast-blow fuse quickly and reliably disconnects the tester circuitry, preventing a short-circuit accident.
Features:
- Clamp-on sensor based current measurement eliminates the cause of accidents
- Accurately measure the fundamental wave alone by eliminating harmonic components with the DMMs low-pass filter function.
- True RMS measurement for accurate measurement of even distorted current waveforms
- To ensure operators ability to use measuring instruments safely, IEC 61010 classifies the locations in which instruments are used into a series of safety-based measurement categories (ranging from CAT II to CAT IV). Using an instrument that does not satisfy the required safety level can lead to an electrical accident.
