5．Usage Direction
5.1 Power ON/OFF
1. Press key on panel board to switch on the unit.
2. press and hold key for three seconds to switch off the unit.
5.2 optical Laser Source Module
1. Switch on the unit.
2. Press key to choose laser source module on the left top of LCD,press”Ok”key to confirm.
3. Choose operating wavelength and mode of operating as per the display of LCD.
5.3 Absolute optical power measurement
1. Switch on optical multi-meter.
2. Set the operating wavelength,press key to choose the “optical power meter module” on the left top of unit,press”OK”key to confirm.
3. Press up down left right key to set the wavelength,press”OK”key to confirm.
4. Access to the measured light,the LCD displays the current measured values,including absolute power of linear and nonlinear values,if the measured light is modulated signals,ａnd it s the modulation frequency of measured signal.
5.4 Relative optical power measurement
1. Set the measuring wavelength.
2. In the absolute optical power measurement mode, measure the current power value by access to measured light.
3. Press“REF”key,the current value of optical power as the current reference value(in dBm as the unit),this time displays the current absolute power value and relative power value of 0dB.
4. Access to another measuring light,displays the current absolute power value and relative power value.
