【 CAUTION 】 (1). The input port ferrule must be kept clean and free of dust and dirt at all times. Take particular care when removing and fitting the connectors. Be sure to use the protection cap or cover when the unit is not in use. For removing dust or dirt from the ferrule face, 2.5 mm CLETOP sticks are recommended.
1. Characteristics (1). The Model 219 lightweight pocket-type MiNi optical power meter is designed to measure optical power and attenuation in high-power fiber optic communications. (2). It is calibrated at four wavelengths: 850nm, 1310nm, 1490nm and 1550nm. (3). It can be used with various kinds of connectors by using the appropriate connector adapters.
⑥ 3. Operating Instructions ③ 3-1 Descriptions ④ ① ON /OFF ON : Press this button to operate the unit. auto power-off function ② activates. To disable the auto power-off ① function, hold this button down for approximately three seconds, until the [Auto-OFF] indicator is disappeared.
⑦ Cover The cover protects the input port, the operation buttons and the LCD display area when the unit is not in use. 3-2 Operation Rear side (1). Battery AA Battery Slide the battery cover off as indicated. Insert or replace one AA battery as indicated by the polarity marks in the battery compartment.
(6). Measurement To assure accurate measurements, tighten the connectors securely, maintain the physical configuration of the fiber during measurement, and do not allow ambient light to enter the sensor. If optical power input falls outside of the measurement range during operation, range indicators will appear in the display as: over (Hi-dBm) and under (Lo-dBm).
3-4 Cleaning the input port Because the path traveled by light, at the PC polished input port, is extremely small, any dust on the ferrule face not only disrupts connection with the fiber, but also leads to greater coupling loss and reflection.
