    Clearance of 5 cm at the rear side of the unit should be allowed for proper ventilation. Don't remove rubber feet to ensure air intake. The mainframe of the MPM-210 weighs about 6.0 kg. Please ensure that the table or shelf upon which it is installed has sufficient strength.

  • Page 20: Line Fuse

    The MPM-210 (Optical Power Meters) measures optical power by converting optical power to electrical power of photo detector, and then measuring electrical power. If there is electrical offsets, the MPM-210 may not allow you to measure optical power with accuracy. So, we recommend you performing the zeroing whenever tuning on this instrument or before you need an important measurement.
