Product Description
The DT4282 is a high-precision 60,000 count digital multimeter with direct 10A input and all of the functions and features required for advanced testing in laboratories and R&D.
- 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)
- Measure up to 10 A with direct input (DT4282 only)
- Terminal shutter mechanism (prevents erroneous test lead insertion)
- Dual display lets you check voltage and frequency simultaneously
