RM-8900 AUTO KERATO-REFRACTOMETER
KR-8900
INTRODUCTION Thank you for purchasing the Auto Refractometer RM-8900, Auto Kerato-Refractometer KR-8900.
This instrument is used to measure the spherical refractive-power,cylindrical refractive power, the direction of astigmatic axis, the radius of curvature, the direction of principal meridian and the corneal refractory power. This instrument features the following: • Measures the refractory power of eye and the corneal curvature with simple operations. • The minimum measurable pupil diameter is now smaller and thus the measuring range is extended. • The auto start function facilitates quick measurements under the optimal condition. This Instruction Manual covers an overview of the basic operation, toroubleshooting, checking, maintenance and cleaning of the Auto Refractometer RM-8900 and Auto Kerato-Refractometer KR-8900. To get the best use of the instrument, read Safety Displays and Safety Cautions. Keep this Manual at hand for future reference.
PRECAUTIONS • Since this product is a precision instrument, always use and keep it in a normally controlled living environment, within a temperature range of 10-40°C, humidity levels between 30-90% and an atmospheric pressure range of 700hPa-1,060hPa. The instrument should also be placed away from direct sunlight. • To ensure smooth operation, install the instrument on a level floor free of vibrations. Also, do not put things on the instrument. • Connect all cables properly before using. • Use the power at a rated voltage. • When not in use, switch off the power source and apply the measuring lens cap and dust cover. • For accurate measurement results, take care to keep the examination window clean and free of fingerprints, spots and dust.
This symbol is applicable for EU member countries only. To avoid potential damage to the environment and possibly human health, this instrument should be disposed of (i) for EU member countries - in accordance with WEEE (Directive on Waste Electrical and Electronic Equipment), or (ii) for all other countries, in accordance with local disposal and recycling laws.
