How to use digital multimeters
This video introduces how to use the DT4280 series of digital multimeters as well as some of the instrument’s featured functionality. Hioki multimeters are engineered to help professional electricians do their jobs safely and quickly.
- 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
