DIGITAL MULTIMETER DT4281/DT4282 DMM Speedy Performance of Professional Testing Two models provide high accuracy and fast response DC V ± 0.025% Basic Accuracy AC V 20 to 100kHz Frequency Characteristics Rich feature set to improve efciency LPF Memory No ‘A’ Terminal Safe, durable design CAT IV 600V Anti-Shock Design – Drop Proof DT4282 DT4281 Current measurement available with optional clamp. Survives 1m drop to concrete. Terminal Shutters – prevent erroneous test lead insertion Unnecessary terminals are closed by the rotary selector. Broad operating temperature range -15°C to 55°C

2 Improves efciency with useful functions suitable for professional testing such as new energy development and facility maintenance Additional Function Filter function Hold display value Auto Hold Relative display General Description Harmonic noise removal, fc = 630 Hz AC voltage, DCV + ACV measurement (AC600V/1000V only) Press [HOLD] to hold the displayed value. Automatically holds the display when the measured value becomes stable (within the set threshold range). Press [REL] to display relative values, taking the currently measured value as the reference value. Additional Function Max/Min...
