Efficient, High-precision Measurement
Like the DT4282, the DT4281 delivers the fastest response speed of any portable multimeter, improving the response time for DC measurement from previous models' 1.5 seconds to 1.0 seconds. it also offer exceptional noise resistance and yield stable measurement results immediately after measurement. Faster measurement lets technicians perform their tasks at a higher level of efficiency. Thanks to safety performance that allows use in applications up to CAT IV (600V), the most demanding measurement category, and an operating temperature range of -15°C to 55°C, the instruments are safe and 100% reliable.

High-accuracy, broadband measurement
With basic accuracy of ±0.025% for DC voltage measurement and a frequency band of 20 to 100 kHz for AC voltage measurement, the DT4281 delivers the highest accuracy and widest frequency band of any portable multimeter. Since measured values are true RMS values, the unit's indicated measurements are accurate, even when measuring a distorted waveform. Its ability to conduct high-accuracy, wideband measurement makes it ideal for use not only in the field, but also in research and development work, where high-performance is a must.

Unlike other TRMS-type instruments that are unable to measure voltage on the secondary side of an inverter, the DT4281 incorporates a low-pass filter function that enables them to make such measurements by eliminating the carrier frequency component. In this way, the instrument also serves as useful tool in inverter research and development.

Terminal shutter mechanism prevents mistaken test lead insertion
Because digital multimeters can measure numerous parameters such as voltage, current, and resistance, they have multiple input terminals, making it possible to insert measurement leads improperly. The DT4281 incorporates a shutter designed so that only the terminals needed for the measurement parameter in use are exposed when the user turns a rotary switch.

Backlit display facilitates use in dark locations
Both the DT4281 features a backlit screen. The white backlight is activated by pressing a display button, allowing measured values to be read accurately, even in dark locations. Additionally, the display will turn red if a voltage of 1,000 V AC/DC or greater is input to the instrument, providing an easy-to-understand warning of a potentially hazardous situation.

Internal memory capable of storing up to 400 data points
The DT4281 can store up to 400 data points. This capability dramatically boosts work efficiency when performing a large number of measurements, for example in battery maintenance work. Additionally, the optional communications package can be used to download measurement data to a computer or save graph displays and data in real time.
