will be not power off automatically. 

 

Pressing “    ”key for a longer seconds to turn off the unit. 

 

Wavelength shift, VFL and Optical Power Measurements 

Pressing “Laser” keypad to open or close 650nm VFL, when VFL is activated, 650nm will display on the LCD 
and the user that cannot perform optical power measurements. 

Pressing Mode to adjust the output power of VFL. The default output power is 10mW, and can be adjusted 1mW, 
5mW.  

 

 

 

 

 

 

 

 

Pressing “λ” to shift wavelength of optical power meter measurement. 

Pressing “UNIT” to shift units between dBm and mw. 

Pressing “REF” for short time to shift between dB and dBm. 

Pressing “REF” for a longer time to set the current optical power value as a reference. 

 

To avoid risk of eye damage, DO NOT look into the interface when VFL is activated.
