Maintenance
To ensure the accuracy of the instrument and prevent it from damage, please pay attention to the maintenance.
Some points for attention are hereby given:
6.1 The instrument should be placed in a dry and well-ventilated room, so as to prevent the optical components
from becoming damp and going moldy.
6.2 After measuring corrosive liquid, it it necessary to do cleaning without delay (including optical components,
metal parts and painting surface), so as to prevent the instrument from corrosive damage.
6.3 No solid impurityis permitted to exist in the sample to be measured. When measuring the solid sample,
prevent the working surface of the refracting prisms from being roughed and scratched.
6.4 Regularly keep the instrument clean. Strictly prohibit hands wet with oil or perspiration from touching the
optical components. If the surface of optical components is contaminated by dirt, use high-grade chamois or
long-fiber absorbent cotton to gently wipe away and blow out with leather blower. If the surface of optical
components is contaminated by greasy dirt, clean out with the mixed solution of alcohol and diethy1 ether
without delay.
6.5 The instrument should avoid violent vibrations or shock, to prevent the optical components from being
damaged, and keep the accuracy of the instrument as well.
