1. Characteristics
All the machines such as ECP-5400, ERK-7800, and PCs could be connected with and used by
one cable, usin RS-485 network method.
By maximizin compatibility amon products, you can deal with the information about Visual
Acuity Test eaily. S/C/A information tested by ERK-7800 and ERK-7800 automatically comes out,
and you can save this information in Di ital Refractor body, only by pressin [LOAD] button.
A wider and clearer screen on 8” TFT COLOR LCD improves data reco nition, so that allowin
more accurate visual test possible.
Lens operation is speedy, and consecutive operation of jo shuttle does not skip any data,
allowin more accurate and prompt vision test possible.
To minimize interruption for control power, an auto-shieldin 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 Conver ence Test.
Help files and real-time uide help a fast and easy unit-test.
By installin 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 pro rams are always available throu h easy and fast update of the pro rams with USB
and P/C.
