Page 4: Function Introduction
1. Function Introduction Uses PM 200 is a digital precision optical instrument used to measure stance between human pupils in the process of optometry for fitting ectacles. Characteristics This device is designed in a scientific and reasonable way, integrating technologies on optics, mechanism, electricity and microcomputer into whole. -

Pupillary distance Conversion Key 7. Measuring State Transition Key 5. - Page 6 in opposite direction of the nose bearer. Now numerical value of the pupillary distance increases, and every pressing of the key will enable the pupillary distance pointer to move 0.5mm, with Right data being increased by 0.5mm. 3. Left Pupil Measuring Key It is used to measure left pupillary distance.
- Page 7 Important Matters Information on the reading display window do not appear simultaneously, instead, they will appear only when you need to measure a given state. 5. Memory Key It is used to store the current data. Press the key once to save the data and press again to cancel the saving.

- Page 9 5. Forehead bearer The testee’s forehead reasts on the forehead bearer so that the position of his pupils is fixed. Viewed from the Measuring Window (as shown in Fig.4) Pupillary Distance Pointer The widths in the observation windows of the device are 0.45mm vertical black lines, one in the left window and the other in the right window.

Please operate it according to the following procedures, thus you can get measured data easily and rapidly. - Page 12 About Baffle Open the baffle (as shown in Fig. 7) Push the baffle switch in the arrow direction, thus the baffle can be opened. Fig. 7 Start-Up (as shown in Fig.8) Press RESET key to make the start-up of the device initialized. After that a micro- processor in the device sets and right pupillary distance pointers at the middles of the left and right measuring windows, and the data on the corresponding digital liquid crystal display windows are shown as follows respectively: LEFT 31.5mm,...
- Page 13 3.4.2 Put the nose bearer lightly on testee’s nose bridge and keep the device in a horizontal state. 3.4.3 Let the testee stare at the staring target of the device. Important Matters In the process of measurement (and the measurement of monocular pupillary distance described in the following section), to achieve precise data of measurement and make process of measurement easily and quickly, the tester should remind the testee to always stare at the Staring Target in a level state, without moving his (her) eyeballs.
- Page 14 Fig.9b (It is the state of the display window when Left eye pupillary distance is measured) Important Matters When measuring right eye pupillary distance, the right observation window is in the state of measurement, and left observation window becomes the following state: immeasurable area is black and measurable area is black-white strip, and then pupillary distance pointer is invisible (as shown in Fig.
