Notes
1.All technical specifications were tested at T=23±2°C.
2.Measurements were conducted after a 15-minute preheat period with the 1550nm light source activated.
3.Battery life was tested with the backlight turned off for continuous operation. Using the backlight continuously may reduce operating time.
