  • ±0.3% DC V basic accuracy, wide 40 Hz to 1 kHz AC V frequency characteristics
  • Low-pass filter (100Hz/500Hz) cuts high harmonics
  • Includes multiple measurement functions such as capacitance, and frequency
  • Current input terminal eliminated to enhance safety (only for DT4251)
  • Measures large currents with optional clamp probe (only for DT4251,DT4253)
  • USB communications function supports PC measurements (optional)
  • Broad -10 (14°F) to 50°C (122°F) operating temperature range

Regarding DMM Accuracy

Due to the many ranges and functions available in a DMM, only the basic accuracy is indicated for reference. Please refer to the individual catalogs for detailed accuracy information
