Speedy Performance of Professional Testing – Two Models Provide High Accuracy and Fast Response
- 60,000 count, 5-digit display, high-resolution measurements
- ±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)
- Includes multiple measurement functions such as DC+ACV, temperature, capacitance, and frequency
- Includes terminal shutter mechanism for accident prevention (prevents erroneous test lead insertion)
- Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention)
- USB communications function supports PC measurements (optional)
- Broad -15 (5°F) to 55°C (131°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
