is below 3, the measurement will be in orange. It is recommended that you take an additional
measurement.
Note: When IOPcc is higher than IOPg, this indicates that the IOP for this patient may be being
understated using traditional methods of tonometry.
Note: When IOPcc is lower than IOPg, this indicates that the IOP for this patient may be being
overstated when using traditional methods of tonometry.
Alignment and Measurement
When power is applied to the Reichert 7CR, it initially performs a system check. After completion of
the system check, the title screen will be displayed.
16060-101 Rev. M 19
Alignment and Measurement
A message will be displayed to move the Forehead Rest fully to the left or right until it locks into
position if it is not already in this position. From this screen operators may choose to enter the
Menu, demonstrate the airpuff to the patient, or begin the measurement process.
Demo Puff
Touching the DEMO icon initiates a sample air puff. This can be used to demonstrate
the air puff to the patient. After each time the DEMO button is pressed and the air puff
is delivered, an internal check of the Reichert 7CR’s systems is conducted to ensure
optimum performance of your instrument.
Note: The DEMO icon will not display if there are measurements displayed on the screen.
If the forehead rest is not in position, the icons will be inactive, and the message in the image below
will appear.
The side that is ready to measure will become blue, indicating the unit is ready to measure that eye.

Alignment and Measurement
Slide headrest left or right
The Reichert 7CR features a left/right sliding forehead rest that enables the instrument to
automatically determine which eye is being measured. It must be positioned completely to one side
or to the other in order to take a measurement. Position the forehead rest to the desired position
before beginning the measurement process.
