  6. OPERATIONAL INSTRUCTIONS • Couple the light to be analyzed into a 50-m delivery fiber. Keep the energy and power of the coupled radiation below the damage threshold of the fiber tip/volume. • Attenuate the peak power of the optical pulse exiting the fiber to less than 100 mW. NOTE: if the photodetector input peak power is greater than 200 mW, the detector may be damaged and the warranty will not apply. • Connect the photodetector to an oscilloscope using a high-bandwidth SMA adapter. Using cables or low-bandwidth adapters will significantly degrade the quality of measurement. • Slowly insert the FC fiber connector into the photodetector fiber receptacle while watching the electrical signal on the oscilloscope. The maximum value of the signal must be lower than 2 V into 50 Ohm. Attenuate the input signal until the fiber connector can be completely inserted into receptacle without exceeding 2 V of output signal. • Upon completion of measurements disconnect the fiber from the photodetector or block the fiber input from the radiation to prevent unnecessary battery drain. • Always use protective plastic caps for the detector receptacles and fiber connectors.

Four #2-56 screws – SAVE THESE! • Changing the battery pack: • Unscrew four #2-56 screws (one at each corner) that hold the battery pack and the electronic compartment together. SAVE THESE SCREWS. • Remove the old battery pack and discard it. • Attach a new battery pack with four #2-56 screws. The battery pack has 90º rotational symmetry. Align it to the electronics compartment in any orientation.
