OPERATING PROCEDURES: Preparation for Measurement

2.2.1 Measuring window check for soiling and puffed air pressure

check during startup

It is possible to parameter-set whether or not to check the measuring window for soiling and

the pressure of puffed air before measurements.

For the details of the parameter setting method, see “2.8 Parameter Settings” (page 76).

The soiled measuring window will adversely affect the reliability of measured results. It is

recommended to keep the measuring window clean with this window check function as well

as by visually checking the measuring window for soiling.

It is essential to maintain the accurate pressure of puffed air for the accurate tonometry. It is

recommended to check the pressure of puffed air before NT measurement.

Checks are performed in the following order: “Check of the pressure of puffed air (40 mmHg

and 60 mmHg)” → “Window check for soiling”

The checks disabled by the corresponding parameters are skipped.

1) After the title screen is displayed, “PRES-

SURE TEST MODE / CHECKING 40” is dis-

played and the test of the puffed air of 40

mmHg is performed.

Wait until the check result is displayed.

No. Parameter name Description

61 WINDOW CHECK

Selection of whether or not to automatically check the measuring

window for soiling from YES, NO, and DAY.

71 PRESSURE CHECK

Selection of whether or not to automatically check the air pressure

from YES, NO, and DAY.

• For checking the measuring window, be sure that the front is not blocked by objects or

exposed to interference light.

Even if the window is not smudged, it may be determined that it is smudged due to objects or interference

light.

• At device start-up, do not stand or put objects in front of the measuring window.

If something is present in front of the measuring window within 1 m, the measuring window may not be

properly checked for soiling.

• All the checks are performed automatically.
