All Model 1815-C Optical Power Meters are carefully assembled, tested, and
inspected before shipment. Upon receiving this instrument, check for any
obvious signs of physical damage that might have occurred during shipment.
Report any such damage to the shipping agent immediately. Retain the
original packing materials in case reshipment becomes necessary.
The Model 1815-C Optical Power Meter should have some operations per-
formed before measurements are made. These include:
• Connection and calibration of the detector (Section 2.4.3 and 2.4.4)
