Thank you for purchasing the Accumulated UV Meter UIT-250.
This manual provides a summary for the Accumulated UV Meter UIT-250 as well as
instructions for its use.
Keep this manual in a safe place in order to be able to refer to it at any time.

Precautions for use

These "precautions for use" describe information that needs to be followed in order to use
this product correctly and safely. Read this portion carefully and make sure that you

Sections that display this are content where "Failure to

heed could lead to injury or physical damage".

This is noted for items concerning operation and main-

tenance of the equipment that are important to know or

if not in compliance or corrected damage may be caused

to the unit.

   

Warning

The UV leaking from the UV curing system can damage you eyes or skin within

a short period of time. When using the UIT-250 near a leaking UV, be sure to wear

protective glasses, and do not expose your skin directly to the UV. The recom-

mended protectors are:

- Protective glasses: RS-24U (SPL3~5) manufactured by Riken Optics.

- Protective mask: UV protector mask manufactured by USHIO INC.

(Drawing No. 2046-1981)

The heat shield cover may be heated to a high temperature of 60

°

C or more when

the UIT-250 is placed on the conveyor of a UV curing system (UNICURE). Be

sure to handle this cover carefully so as not to cause and injury, such as a burn.
