1.1. Outline of the instrument
1.2. Classification
Protection against electric shock: Class I(earthed)
Installation Category: II
Pollution Degree: 2
The Automatic Lens meter LM-7800 is the equipment for measuring the refractive
power of lenses and gives the spherical, cylindrical and axis of the lenses.
The Automatic Lens meter LM-7800 also contains the PD(=pupil distance)
measurement and the UV Protection Ratio Test. The automatic lens meter
LM-7800 can measure both the uncut singular lenses and the framed glasses.
