Key Features
-
The DT4281 is our top-of-the-line high-precision 60000 count digital multimeter with all of the functions and features required for advanced testing in complex power and electrical applications
-
±0.025% DC V basic accuracy, wide 20 Hz to 100 kHz AC V frequency characteristics
-
Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
-
Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention)
-
Terminal shutter mechanism (prevents erroneous test lead insertion)
-
Dual display lets you check voltage and frequency simultaneously
-
The Ultimate Digital Multimeter, Featuring A Design Focused On Safety That’s Critical For Electrical Work
-
The DT4281, which is part of Hioki’s DT4280 series of high-end digital multimeters, is designed for maximum safety in electrical work
-
Connect an AC clamp to safely measure current
-
Accurately Measure The Voltage Output From The Secondary Sides Of Inverters By Eliminating Harmonic Components
-
Measure the fundamental wave alone by eliminating harmonic components with the DT4281’s low-pass filter function
-
Measure The Ripple Voltage Of DC Charging Systems
-
Measure ripple voltage with a superposed DC signal by using peak value measurement and DC + AC voltage measurement
-
Percentage Display For 4 To 20 mA Instrumentation Signals
-
The digital multimeter can convert and display instrumentation signals of 4 to 20 mA or 0 to 20 mA representing properties such as temperature, pressure, and flow rate from a transducer or other device that converts sensor data into an electrical signal
-
600.00 μA Range For Measuring Very Low Currents Used By Gas-Burning Devices
-
Accurately measure the very low currents such as burner flame currents
-
Clamp-On Sensor Based Current Measurement Eliminates The Cause Of Accidents
-
Mistakenly measuring voltage using the current range may lead to a short-circuit
-
The DT4281 eliminates the root cause of such accidents by providing clamp-on sensor based current measurement functionality instead of using conventional probes
-
True RMS Measurement For Accurate Measurement Of Even Distorted Current Waveforms
-
Digital multimeters implement two types of measurement: mean-value measurement and true RMS measurement
-
The two methods yield significantly different measurement results for current waveforms, which are often distorted
-
For accurate measurement, it is necessary to use an instrument with true RMS capability
-
Measurement Data Can Be Downloaded To, Reviewed On, And Saved To A Computer
-
Connect the DT4281 to a PC with the optional Communication Package DT4900-01 to easily graph data stored in the DMM’s internal memory and display measurement results in real time on the computer
-
Save important measured values in text format
-
Safe Measurement Requires Use Of An Instrument That Suits The Measurement Location
-
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
