Better than 0.5% accuracy DC | Wireless Range |
Better than 1.0% accuracy AC for harmonic content below 1kHz | The wireless range has been tested empirically through the following media to an iPhone 5. |
>10 Megaohm input impedance | |
50m air, line of sight | |
High Precision Voltage: | 5cm of refrigerator, door closed |
Up to 100mV with <15nV per count resolution | Engine compartment to the passenger seat of most vehicles |
Up to 1.2V with <200nV per count resolution | 10m air + safety shield of a Tesla Coil rock-bands testing facility |
>10 Megaohm input impedance | |
If used outside of the measurement range (0-1.2V), the overvoltage protection circuit will short this to the common (“C”) input. | Applications |
