Product OverviewThe Hioki DT4252 is a professional-grade, general-purpose True RMS digital multimeter (DMM) from the robust DT4200 series. It is engineered for industrial and field maintenance, providing high-speed response, high safety ratings, and precise measurement capabilities. With its ability to handle both voltage and direct current (up to 10 A) and its integrated low-pass filter, it is a versatile choice for diagnosing electrical panels, inverter output, and general electronic control circuits.Key FeaturesTrue RMS Measurement: Provides accurate readings on non-sinusoidal waveforms, which is essential when testing inverters, variable frequency drives (VFDs), and switching power supplies.Low-Pass Filter (LPF): Effectively cuts high-frequency harmonic noise, allowing you to isolate and accurately measure the fundamental voltage frequency on the secondary side of inverters.Direct Current Input: Capable of measuring up to 10 A directly through the input terminals, covering standard industrial current testing requirements.Safety & Durability:Safety Rating: CAT IV 600 V / CAT III 1000 V.Rugged Build: Dust-proof enclosure and drop-proof housing (tested for 1-meter falls onto concrete).Wide Temperature Range: Operates reliably from -25°C to 65°C.Advanced Functionality:Dual Display: Allows for simultaneous viewing of voltage and frequency.USB Connectivity: Optional communication package allows for real-time PC data logging, graphing, and reporting.Smart Hold: Features "Auto Hold" to freeze readings automatically when they stabilize, which is convenient when working in hard-to-reach areas.Technical SpecificationsFeatureSpecificationBrandHiokiModelDT4252DC Voltage600.0 mV to 1000 VAC Voltage6.000 V to 1000 V (True RMS)DC Current6.000 A / 10.00 AAC Current6.000 A / 10.00 AResistance600.0 Ω to 60.00 MΩCapacitance1.000 μF to 10.00 mFFrequency99.99 Hz to 99.99 kHzSafety RatingCAT IV 600 V / CAT III 1000 VDisplay4-digit LCD (max. 6000 count) + bar graphPower Source4 x LR03 (AAA) batteries (~130h continuous use)Dimensions84 x 174 x 52 mmWeightApprox. 390 g (including batteries/holster)SEO KeywordsHioki DT4252, True RMS Multimeter, Industrial Digital Multimeter, Electrical Diagnostic Tool, 10A DMM, Low-pass Filter Multimeter, Hioki DT4252 Specs, CAT IV 600V Multimeter, Inverter Testing, Professional Field DMM.
