Note:

* : the related technical indexes were tested at T = 23 ± 2 °C.

1. The instrument was preheated for 15 min by 1550 nm light source.

2. Testing at@1550nm.

3. The continuous working time of the battery is tested when the backlight of the meter is turned off, and the continuous working time of the continuous working time of the backlight of the meter is relatively shortened.
