This document introduces the features and applications of the RuiFu desktop 570 series optical power meters 575L, 577L, and 578L in Room 1001, Huaying Building, Nanshan District, Shenzhen. They have a wide measurement range, high resolution, remote control capabilities, etc., and are suitable for insertion loss and link loss testing.
The Richen 570 series light power meters (models 575L, 577L, 578L) are designed for insertion loss and link loss testing in production and laboratory environments. The manual provides detailed specifications, interface options, and instructions for remote control, data logging, and custom label printing.
Key features include a measurement range of +3 to -75 dBm, InGaAs detector, multiple calibration wavelengths, RS‑232 remote control, BNC analog output, and the ability to connect up to 16 meters in a multi‑channel system. Ordering information and part numbers for each model are also included. This manual is written in Chinese.
| Power range | +3 to -75 dBm |
|---|---|
| Resolution | 0.01 dB/dBm; 0.001 mW |
| Detector type | InGaAs |
