Clearing Results to Re-refract
The last refraction for one or both eyes remains in the instrument’s memory until another
refraction is initiated or the five-minute time-out limit is passed. There are two ways to
clear refraction data from the display immediately if you would like to re-refract an eye.
1. Reposition the optics head. If you have measured both eyes, moving the optics head
back to the first eye will clear data for that eye and allow you to take another
measurement. Results for the second eye will remain on the display unless the optics
head is moved to that eye a second time.
2. Print results. Pressing the Print button prints out the examination results, clears the
patient’s data from the refractor, and prepares the instrument for the next patient.
Turning off the power also erases all stored refraction data.

The Model 5000 Printout
The Acuitus does not store a patient’s measurements; you must print them out after each
examination. You may print after each eye is measured, but most practitioners prefer to
have the results for both eyes on a single printout.
The refraction results from the Acuitus 5000 can be printed out in the complete format or
with some or all options suppressed. Use the setup screens to select or suppress options
(see page 5). You may also choose to print results either on the standard paper or on an
adhesive label that may be affixed to the patient’s chart.

5010/5015 Keratometry Screen
(Refraction Disabled)
Central Keratometry
If you are operating the Acuitus 5010/5015 in the automatic mode, it will take central keratometry
measurements automatically and display the results as soon as the eye is aligned. When you follow
refraction with central keratometry, the instrument will refract the eye and proceed automatically to
keratometry. If you are using the manual mode, press the button on the joystick as soon as the eye is
aligned.
Peripheral Keratometry
Because the patient must be asked to look at a series of four fixation targets, peripheral keratometry cannot
be performed in the automatic mode. If you are using the automatic mode, the Acuitus 5010/5015 switches
to the manual mode when it is time to take the peripheral measurements.
The screen prompt will tell you when to ask the patient to look at the first fixation target. Tell the patient to
continue facing straight ahead and look at the first light. When the patient is looking at the target, push the
button on the top of the joystick. The prompt will then tell you to ask the patient to look at the second
target, and so on until all four measurements are complete.
Keratometry Printout Options
If both refraction and keratometry have been performed, the keratometry results appear on the printout after
the refraction results with, again, the results for the right eye first (see the sample printout on page 12). If
keratometry has been performed alone, the printout will show keratometry only.

Maintenance
Replacing the Printer Paper
The Printer Not Ready message appears on the screen when the paper supply is completely empty. To
avoid the risk of losing patient data, it is better to change the paper roll when the red, end-of-roll, line
appears along the edge of the printout.
If you run out of paper while you are printing patient data, you will be able to restart the printer after you
have put in new paper. No patient data will be lost.
If you replace one type of paper with another, standard with label, for example, be sure to go back to the
second setup screen (Press Help, then Setup, then Page Down) and change the paper type in the printer
options.
Note: It is not necessary to turn off the power to replace the paper. If you do, you will lose any
patient data that is currently stored in the instrument.
To replace the paper
1. Push the printer lever on the side of the instrument (see page 1) to the unlocked position and slide the
printer straight out of its housing.
2. Push the paper feed lever on the side of the printer forward to release pressure on the platen.
Printer lever moved to the unlocked position Paper feed lever
3. Remove the cover on the paper tray and lift out the empty paper roll.
4. Put in a new paper roll, orienting it so that the paper feeds up from the bottom. Feed the paper through
the slot until it comes out the front of the printer.
5. Relock (push back) the paper feed lever.

6. Gently push the printer back into place until it stops. Then return the printer lever on the side of the
instrument to the lock position. Push the printer all the way in.
7. Press the Print button to test.
Checking Calibration
The calibration on the Humphrey Acuitus is very stable. However, calibration can be affected if the
instrument is moved with the optics head unlocked, or if it is bumped or tipped. It is a good idea to check
calibration once a week and after every time the instrument is moved.
Your Acuitus Accessory Kit includes a “test eye” piece that simulates a human eye with known
measurements. To use this test eye piece to check the your refractor’s calibration:
1. Note the reference values marked on the test eye piece.
2. Attach the test eye assembly to the forehead rest by inserting the tabs into the slots on the forehead rest
and pushing down.
3. Align the test eye in the monitor by moving the joystick as you do for a refraction.
4. Press the button on the top of the joystick to take a measurement if you are using manual mode. In
automatic mode, the Acuitus will measure the test eye and display the results as soon as the test eye is
aligned.
Test eye
5. Check to make sure that the measured values correspond with those marked on the test eye piece.
Zeiss Humphrey Systems Acuitus User Manual
PN 50648 Rev A June 2001
17
If the measured values do not match those of the test eye, check the alignment in the fixation window and
take a second measurement. You should also make sure that the lens in the patient fixation window is not
dirty (see below). If the instrument still seems to be out of calibration, call Humphrey Systems Customer
Service.
Cleaning the Patient Fixation Window
Check the fixation window regularly for dust and smudges because a dirty lens can cause erroneous
readings. Unusually high sphere or cylinder readings can be the result of dirt on the patient fixation
window.
Note: The lens in the patient fixation window has a special coating that is easily scratched. Take care
in cleaning it.
To clean the window, first use a camel hair brush to gently remove the dust from the lens. Then dampen a
lintless camera lens tissue with a camera lens cleaning solution and gently wipe the lens surfaces to remove
smudges or fingerprints.
Cleaning the Screen and Outer Casing
Wipe the screen with a clean, dry cloth. Do not use any cleaner.
Clean dirt spots and dust from the outer casing with a clean cloth and mild detergent or isopropyl alcohol.
Never spray detergent or alcohol directly on the casing.
For reasons of hygiene, be sure to wipe the forehead rest and the chin rest with an alcohol swap after each
patient.
Changing the Fuses
Two fuses are located in the fuse box on the side of the instrument just above the on/off switch and the
power cord attachment. Your Acuitus accessory kit contains two replacement fuses of the correct type and
rating.
To change the fuses:
Turn the instrument off and unplug the power cord.
Use a small screwdriver to gently pry open the cover to expose the fuse holders (marked with an arrow).
Slide out each fuse holder and check the filament for breakage. Remove the defective fuse.
Insert a new fuse in the fuse holder. Slide the fuse holders back into the housing with the arrow pointing to
the right. Push the cover up and in until it snaps in place. Plug in the power cord.
Caution: Use replacement fuses of the correct type and rating (T 2.0 slow blow, 250V). Failure to do
so could damage the instrument.

Warranty
For one year from the date of delivery to the original purchaser, Seller warrants its Acuitus (the
“instrument”) to be free from defects in material and workmanship. In the event of failure, Seller’s
obligation is limited to repairing or replacing on an exchange basis parts which have been promptly
reported by the Purchaser during the warranty period as being defective and are so found by Seller upon
inspection. The procedure for warranty claims shall be as follows: when the Purchaser believes the
instrument defective, the Purchaser shall promptly report the defect to the Seller. The Seller shall repair the
Acuitus in the Seller’s repair depot. All shipping costs will be paid by the Seller, unless the Purchaser’s
Acuitus is found upon inspection not to be eligible for repair under this warranty, in which case the
Purchaser shall be responsible for one-half of the shipping costs. The warranty covers all parts, labor,
shipping and expenses for the warranty period (country specific).
If the instrument is determined to be ineligible for repair under the warranty, Seller will so notify
Purchaser, and repairs desired by Purchaser will be performed at Seller’s normal rates. All replaced parts
become the property of the Seller. A loaner instrument may be available while Purchaser’s instrument is
being repaired. All shipping costs for loaner instruments to be borne by Purchaser.
The warranty does not cover consumable items such as operating supplies, paper, ribbons, bulbs, and
manuals, and will not apply if repair or parts replacement is required because of accident, neglect, misuse,
transportation, or causes other than ordinary use, or supplies that do not meet the proper operating
specifications of the Seller. The warranty does not apply if software unapproved by the Seller is used in the
instrument. This warranty does not apply to any articles that have been repaired or altered except by the
Seller.
Every reasonable effort has been made to ensure that the product manuals and promotional materials
accurately describe the instrument’s specifications and capabilities at the time of publication. However,
because of ongoing improvements and product updates, the Seller cannot guarantee the accuracy of printed
materials after the date of publication and disclaims liability for changes, errors, and omissions. Seller shall
in no event be liable to Purchaser for loss of profits, loss of use or consequential damages caused by the
Purchaser’s failure to fulfill the Purchaser’s responsibilities as to proper installation, use, management and
supervision of the instrument. This warranty shall apply only to the original Purchaser and shall not, in any
way, be transferable or assignable.
The foregoing warranty is in lieu of all warranties, express or implied, including, but not limited to, the
implied warranty of merchantability or warranty of fitness for a particular purpose. (All Specifications are
subject to change without notice.)
Service Contract
A Warranty Extension Agreement (Service Contract) is available after the one-year warranty period expires
and may be purchased at any time. This Warranty Extension is for one year and is subject to the Terms and
Conditions applicable to the specific instrument. Please contact Customer Service for details.
