Page 2: Safety Instructions
Users should avoid looking directly into the optic output of OVA-50. And the use of microscope or magnifier should also be avoided, for the use of such devices can focus a highly intense beam onto the retina, which may result in permanent eye damage Battery: OVA-50 battery type is lithium battery. - Page 3 OVA-50 User’s Manual when the instrument is working Always replace protective dust cap on the detector port when the instrument is not in use. Always avoid looking directly at unconnected end of optic fiber in testing and make the unconnected end pointing at a non-reflective object.

2.2.1 External Interfaces Optical Input OVA-50 is available with FC connector (Interchangeable SC/ST). USB Power /Data Port OVA-50 can be charged by external power adapter (5V DC, 750mA). 2.2.2 Keypad Operation Power on/off Toggle between calibrated wavelengths Reset to minimum attenuation value Short press to toggle between working modes: Absolute attenuation, Relative attenuation, Program &... -
Page 9: Indicator
OVA-50 works on lithium battery, please make sure battery is mounted properly before use. When battery is low, low battery indicator will appear on LCD. You can still use OVA-50 as long as its display on LCD is identifiable. Please charge as soon as possible when battery is low to ensure accurate measurement. -

Page 11: Relative Attenuation
Note: 1. Function shown in Figure 3.3 is mainly applied before testing to set the insertion loss for jumper fiber and the instrument to ensure accurate attenuation calculation. 2. Once the insertion loss value is set, press button and OVA-50 will save the value as default minimum attenuation value. 3.3 Relative Attenuation Press button to relative attenuation value mode, see Figure 3.4;... -
