2. Instrument Using
2.1 Installation
Installation location In your workplace, install the RMK-700 Refractometer
in a flat place without direct sunlight and adjust it to appropriate height. The
operating environment temperature is between + 5 ° C and + 40 ° C and the
relative humidity is between 30% and 75%.
In order to avoid damaging the refractometer, it is forbidden to place it on the
following places:
●where particularly hot and particularly cold;
●where the humidity changes tremendously;
●where there is a lot of dust;
●Near electromagnetic equipment of Strong interference.
Installation
●Put it softly on the table;
●Connect the power cord to the socket;
●Ground the earthing terminal in the socket reliably.
Note: The Operation desk should be placed on a flat place during installation and
can be configured by the actual situation.
2.2 Calibration
●Pull the handle, the host should be able to move on the base smoothly and
flexibly;
●Turn on the power switch, and the power indicator light is brighten, then
the screen starts displaying;
●Place the standard model eye on the head rest and fix it with the dowel pin;
●Adjust the height lifting knob so that the standard eye height is roughly
same as the measuring window;
●Pull and turn the joystick to make sure the internal collimation point is at
the center of the corneal ring;
●adjust the joystick front and back to keep the corneal ring focus clearest,
meanwhile internal alignment ring is locked in the internal collimation point;
●Press the measurement key, for a moment the measurement results will be
displayed on the screen. The results should be consistent with the standard
eye;
●Press the print key, the measurement result should be printed out;
●If the above measurement results are consistent with the standard eye
(±0.25m-1 deviation is still normal), and each function keys are working

properly, which indicates that the instrument can be measured normally.
2.3 Measurement
Measure the Model eye before measuring the patient
Measurement Procedure
(1) Turn ON the power
(2) Set the model eye on
Remove the model eye and align the holes of the model eye with the
the chin rest, and insert pins.
(3) Release stage lock
Loose the stage solid bolt downward.
(4) Adjust height of Test Model Eye
Adjust the height of the chin rest by rotating Height Adjustment Knob
so that The Test Mode Eye is aligned with the Height Adjustment Mark on
the headrest.
(5) Enter K﹠R or REF Mode
Press MODE button until either one is displayed.
(6) Adjust the position and focus on the Model Eye.
Note: The Model eye is developed by the National Institute of Metrology, so the
customers configure it according to their own needs.
● Height adjustment: rotate Joystick and Height Lifting Knob of chin rest
to adjust height;
● Focus adjustment: Move the joystick all around, and focus when the
center becomes a cross.
(1) Measurement
● Manual measurement: Press the measurement button. If measurement is

failed with message like TRY AGAIN on the top left corner of the
screen, press the button again;
● Automatic measurement: Push AUTO button at the bottom of monitor.
2.4 Operation method
DIOPTER\REF mode
In the REF Mode, Diopter measurement is performed only.
(1) Enter Mode
Enter REF mode automatically when starting up
(2) Adjust height of examinee's eye
● Have the examinee sit and adjust chair or Refractometer height to make
examinee comfortable;

RMK-700 Operating Manual
12
focusing alignment mark“十”is displayed clearly on the bright point
(4) Measurement
● Press the Measurement button

monitor.
(7) Print
● Press the PRINT button
● The measured results will be printed.
When “TRY AGAIN” appears
，
refer to the following solutions, please.
Cause
Solution
Alignment of the eye is improper
Measure after aligning the pupil and the
alignment mark properly.
Eyelid or eyelashes are covering the
pupil.
Instruct the examinee to open his or her eyes
wide, or lift up the eyelid lightly with your
fingers and measure again.
When the pupil is smaller than the
Alignment Ring.
The minimum pupil diameter that can be
measured is 2.0 mm. Don’t expose examinee’s
eyes to direct sunlight or too bright indoor
lights to prevent contraction of the pupil.
When the examinee has some illness
like cataract.
Impossible to measure.
When the Mire Ring is oddly shaped
because of tears.
Instruct the examinee to open and close his or
her eyes several times and measure again.
