Working environment
1、 Do not hit or drop the instrument. The impact may cause damage to the function of this
instrument. Please handle with care.
2、 An exposure to the direct sunlight or bright indoor lights may influence the result of the
measurement. Please use the URK-800 in an appropriate optometry room.

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
