These settings can be changed to suit the needs of the individual operator or clinician. A summary of these settings is given below with the default selections shown in bold type.
Instrument Setup continued) Tonometer Settings The following options are available in the Tonometer Setup menu: Parameters Settings PRESSURE Choose either millimeter of mercury (mmHg) or kilo Pascals (kPa). MEASUREMENTS Choose either 3 or 4 measurements for the multi-measure button function. AVERAGING Choose either Intelligent or Straight averaging.
Instrument Setup continued) General Settings The following options are available in the General Setup menu: Parameters Settings LANGUAGE Sets the language that appears on the Operator Display. TONE Sets the audible tone indicator (“beep”) to be silent (OFF) or audible (ON). Note: Any time a selection is made on the touch screen, a beep will sound if the option is set to “ON”.

DATE FORMAT Choose the date format to display on the printer paper: D=Day, M=Month, Y=Year.
Instrument Setup continued) Communications Settings The Reichert 7CR can transfer data to an external device, such as a computer, through the USB port. The following options are available in the Communications Setup menu: Parameters Settings BAUD Serial transmission data rate, transfers in bits per second (bps).
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...
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.

(continued) 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.
Instructions For Use continued) Alignment and Measurement (continued) Correct Patient Positioning Set the height of the table so the canthus marks on the sides of the instrument are level with the patient’s eyes. Patients should lean forward slightly so that the center of their forehead rests in the middle of the rubber forehead pad.
Page 22
Instructions For Use continued) Alignment & Measurement (continued) To take a measurement, simply touch one of the measurement icons. • Touching the MEASURE icon (one puff) will initiate a measurement with one puff. • Touching the MULTI MEASURE icon will initiate a measurement with multiple rapid puffs. Note: To ensure fast and accurate results operators should instruct the patient to blink a few times and hold both eyes open immediately before measurement.
Page 23
Instructions For Use continued) Alignment & Measurement (continued) During the alignment and measurement process, the Operator Display will show the position of the airtube with respect to the center of the patient’s cornea. As the positioning system aligns to the apex of the eye, the measuring icon will move to the middle of the screen and align over the center alignment mark (+).
Instructions For Use continued) Alignment & Measurement (continued) Measurement Count The eye icons below the eye titles (Right and Left, or OD and OS) will be filled in to indicate the number of measurements that have been made. When using the single measurement function, an eye icon will become filled after each measurement.
Intelligent Averaging of Data The Reichert 7CR features an intelligent averaging system, based on the waveform score, to help ensure the most reliable measurements are displayed. The system works in the following manner:...
Instructions For Use continued) Alignment & Measurement (continued) Examples - Intelligent Averaging Please refer to the table below for some scenarios that demonstrate how the intelligent averaging process determines the displayed result Measurement Measurement Measurement Measurement Individual IOPcc 17.5 11.0 16.0 16.5 Individual IOPg...
Instructions For Use continued) Alignment & Measurement (continued) Examples - Straight Averaging Please refer to the table below for some scenarios that demonstrate how the straight averaging process determines the displayed result Measurement Measurement Measurement Measurement Individual IOPcc 17.5 11.0 16.0 16.5 Individual IOPg...
Instructions For Use continued) Alignment & Measurement (continued) Measuring the Next Eye There are several options available at this point: a. The Forehead Rest may be slid to the opposite side to continue taking measurements on the other eye. b. All data may be cleared and additional measurements taken on the same eye (touch the CLEAR icon).
Instructions For Use continued) Sleep Mode The unit will go into sleep mode after the specified amount of time selected in the Setup Menu. When the unit comes out of sleep mode, any measurements that were not cleared out prior to sleep mode will appear on the screen, but the measurement buttons will be disabled in order to prevent accidentally combining data from two different patients.
Instructions For Use continued) Low Confidence Readings Any measurement values identified as “Low Confidence” will be indicated in orange text. Take additional measurements to replace the low confidence values. Note: It is possible that post refractive surgery eyes, eyes with corneal pathologies, and glaucomatous eyes will produce consistently low measurement scores.
Positioning Error Messages During the measurement process, the Reichert 7CR may detect a situation where the patient’s eye is too far from the nosepiece. Should this occur, the instrument will return to the home position, and the screen will change to that shown below.
Instructions For Use continued) Printing Measurement Data To print the measurement data, touch the PRINT icon. A sample printout is shown below. Sample Printout If you decide not to make a printout, touch the CLEAR DATA icon. This will clear all data from the memory and the screen.
Cleaning & Maintenance Fuses WARNING: DISCONNECT POWER BEFORE ATTEMPTING TO REMOVE THE FUSES OR SERIOUS INJURY OR DEATH MAY OCCUR. Replace the fuses in the Power Input Module with the fuses indicated in the Specifications section of this manual. 1. Remove input power to the instrument. 2.
Cleaning & Maintenance continued) Positioning Windows and Airtube Cleaning When the Positioning Windows or the Applanation Windows become occluded with contaminants, degradation of the positioning signal occurs. When signal degradation occurs, the system may not recognize or position at the center of the eye. Consequently, the instrument will not find the center of the eye or align off center, which may prevent the unit from taking a measurement or can cause asterisk readings.
Cleaning & Maintenance continued) Forehead Rest Pad Replacement The Reichert 7CR tonometer has a removable Indent Forehead Rest Pad, to allow for easier replacement of the pad. On the bottom part of the Forehead Rest Pad, there is a small indent, which is to allow room Figure CL-1.
Troubleshooting Help Screens The Reichert 7CR includes HELP screens, which provide useful information and tips on its operation. These screens are intended to be used as a quick reference to a selection of operations. To access the HELP menu, touch the MENU icon. Press the DOWN ARROW icon until the cursor box is positioned on HELP.
