The HIOKI DT4253 Digital Multimeter offers fast and professional testing. The standard models ensure a quick response and safety, and are thus suitable for HVAC testing.
The product provides ±0.3% DC V basic accuracy with broad 40Hz-1kHz AC V frequency characteristics. Its high harmonics (when measuring inverter fundamental waveforms) are reduced immensely by a low-pass filter (100Hz/500Hz). Numerous measurement functions, such as frequency, capacitance and temperature, are included. Large currents are measured using an optional clamp probe. It also offers optional USB communications function which enables PC measurements. It operates over a wide temperature range of -15-55°C (5°F-131°F).
