Specifications for N2 - Neuron
| Neuron Specification Table | As of 05/01/2020 |
| Voltage | Radio: |
| Up to 600V, DC or peak AC | Protocol: Bluetooth Low Energy |
| Up to 420VAC RMS sinusoidal | |
| 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 |
