DW-16801 Optical Power Meter can test optical power within the range of 800~1700nm wave length. There are 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm, six kinds of wavelength calibration points. It can be used for linearity and non-linearity test and it can display both direct and relative test of optical power. This meter can be widely used in the test of LAN, WAN, metropolitan network, CATV net or long-distance fiber net and other situations. Functions 1) Multi-wavelength precise measurement 2) Absolute power measurement of dBm or μw 3) Relative power measurement of dB 4) Auto off function 5) 270, 330, 1K, 2KHz frequency light identification and indication 6) Low voltage indication 7) Automatic wavelength identification (with the help of light source) 8) Store 1000 groups of data 9) Upload test result by USB port 10) Real-time clock display 11) Output 650nm VFL 12) Applicable to versatile adapters (FC, ST, SC, LC) 13) Handheld, large LCD backlight display, easy-to-use Specifications
