1. Introduction
The Auto-Refractometer (RM-9600, RM-9800)/ Auto ref-keratometer (KR-9600, KR-9800) is
used to measure spherical, cylinder, axial, PD, corneal radius and corneal diopter (KR-9600,
KR-9800) of the patient’s eye.
1.1 Product Features and Use Scope
a) The classification of equipment according to the type of shock proof: class I, external
power supply equipment.
b) The classification of equipment according to the degree of shock proof: B type.
c) The classification of equipment according to the ability to prevent liquid entry:
ordinary equipment.
d) Application part of the equipment: chinrest, forehead rest.
e) The type of device power: single phase, network power supply: 100-240V ~ 50/60Hz
50VA.
f) Equipment belongs to non AP or APG type.
g) The operation mode: continuous operation.
h) Equipment belongs to impermanent installation equipment.
1.2 Classification
The model number is RM-9600/ KR-9600/ RM-9800/KR-9800.
The Auto Ref/keratometer is composed of the host, the base and the bracket (according to
the appearance). The bracket material is ABS.
The Auto Ref/keratometer is composed of optical system, electronic system and software,
mechanical system, shells (according to the functional system).
The main difference between the main models KR-9000 is the difference in shape. The
principle and intended uses are the same.
The classification of appearance according to design serial number: KR/RM-9600 is same.
KR/RM-9800 is same.
The classification of functional according to model number: KR-9600/9800 is same.
RM--9600/9800 is same. (The Auto Ref/keratometer KR-9600 and KR-9800 can measure corneal
curvature)
