Key features
- 60000 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)
- 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
