| 14 | Laser box: |
| 15 | * Temperature - the first number shows lidar internal ambient air temperature and the number in brackets () shows the temperature of electronics, |
| 16 | * Energy (uJ) – laser pulse energy, Pressure (kPa) – laser gas pressure. |
| 17 | |
| 18 | Gas Refill System box: |
| 19 | * Cylinder (kPa) – internal fresh gas cylinder pressure before the pressure regulator |
| 20 | * Lidar (kPa) – internal ambient pressure of lidar hull |
