| Digits / resolution | 4½ digit; the datasheet header states 60,000 count and its feature list 66,000 count readings resolution |
|---|---|
| DC voltage | 600 mV to 1000 V in five ranges; accuracy ±(0.06% of reading + 8 counts), one-year, all ranges |
| AC voltage (true RMS) | 600 mV to 750 V, AC-coupled; up to 1000 V DC bias permitted on every range; AC filter bandwidth 20 Hz to 100 kHz |
| DC current | 600 µA to 10 A; accuracy ±(0.25% + 4). Above DC 7 A (or AC RMS 7 A), 30 seconds ON followed by 30 seconds OFF is recommended |
| AC current (true RMS) | 60 mA to 10 A; measures AC components only (DC-coupled to the fuse and shunt) |
| Resistance | 600 Ω to 100 MΩ, 2-wire or 4-wire selectable; accuracy ±(0.04% + 6) on the best ranges |
| Other measurements | Capacitance 2 nF to 10,000 µF; frequency 20 Hz to 500 kHz; period 2 µs to 0.05 s; temperature via TC or RTD sensors; diode test (0-4 V at 1 mA); continuity (fixed 2 kΩ range, adjustable threshold) |
| Measurement speed | Up to 150 readings per second |
| Display | 4.3-inch TFT-LCD, 480 x 272, dual display, Chinese and English menus, built-in front-panel help |
| Input protection | 1000 V on all voltage, resistance, continuity and diode ranges; current ranges protected by a rear accessible 10 A 250 V fast-melt fuse and an internal 12 A 250 V slow-melt fuse |
| Math and recording | Min/Max/Average, standard deviation, dBm/dB, relative, pass/fail, hold, histogram, trend chart, bar chart; 10 K readings of history in volatile memory |
| Memory | 1 Gb NAND flash for configuration and data files; supports USB flash drive storage |
| Interfaces | USB 2.0 Full Speed Device and Host, 10/100 Mbit LAN; optional USB-GPIB adapter; standard SCPI command set compatible with mainstream bench multimeters |
| Cold junction | Built-in cold terminal compensation for thermocouple measurements |
| Power supply | AC 100-120 V or 200-240 V, 45-66 Hz; consumption 20 VA max |
| Safety and EMC | Conforming to EN 61010-1:2010 and low voltage directive 2006/95/EC; EMC 2004/108/EC and EN 61326-1:2013 |
| Dimensions and weight | 293.75 x 260.27 x 107.21 mm; 3.76 kg |
| Warm-up | 30 minutes for full accuracy; full accuracy from 0 °C to 50 °C (80% RH to 40 °C, non-condensing) |
| Scanner card | The SC1016 scanner card option is not compatible with the SDM3045X |
