1. Characteristics
All the machines such as CP, RK, LM and PCs could be connected with using RS-485 network
method.
By maximizing compatibility among Unicos products, you can deal with the information about
Visual Acuity Test easily. S/C/A information tested by UDR-800P and URK series automatically
comes out, and you can save this information in Digital Refractor body, only by pressing [LOAD]
button.
Android OS-based Tablet PC improves data recognitions, so that allowing more accurate visual
test possible.
Lens operation is speedy, and consecutive operation of jog shuttle does not skip any data,
allowing more accurate and prompt vision test possible.
To minimize interruption for control power, an auto-shielding function works, when a lens more
than ±0.5D operates.
You can run complicated functions easily with SHIFT keys, and it is convenient to execute
various options for test.
It supports short distance PD (45 ~ 75mm) and short distance work (35 ~ 70cm) to make a
reliable near-distance Convergence Test.
Help files and real-time guide help a fast and easy unit-test.
By installing a printer in the operation panel, you can print the test result promptly.
It inputs eye-test information without lens operation, and offers PRESET function that put in the
lenses at once.
New programs are always available through easy and fast update of the programs with USB
and P/C.
