Page 5: Introduction
1. Introduction 1.1 Uses Principle: The pupilometer takes the advantage of the image-forming principle of optical lens. Optical lens imprints the observed object at a specified distance, then the patient watches at the observed object, and the optometrist can find out the bright points of the observer’s eyes via the measuring window, meanwhile the optometrist moves the left and right measuring keys to make the related mechanical hairsprings to coincide with the bright points of the observer’s eyes,... - Page 6 measurement system, optical system, ESS and microcomputer into a whole. ＊Using mechanical hairspring to level at the reflecting point of human cornea to realize the consecutive measurement. It features directness of point-sampling and high accuracy of orientation. ＊ Adopting line-shaped sensors of high definition, advanced intellectualized electronic systems and digital display which allow the testing results more visible, legible and accurate.

Page 11: Description Of The Structure
3. Description of the structure 3.1 Description of the front panel Fig.1 F1. Measuring Window The working window of the testing personnel. F2. Optic Distance Knob It is used to conduct conversion of measured value of pupillary distance at different optic distances of 30cm ~ ∞. F3. - Page 12 Sliding the key to the inner side will make the pupillary distance pointer move towards the direction of the nose bearer. Now numerical value of the pupillary distance decreases. F4. Function Transition Key PD and VD measurement mode can be switched by pressing Function Transition key.
- Page 13 F6. Nose Bearer The testee's bridge rests on the nose bearer so that the position of the testee's pupils is fied. F7. Observation Window Two windows provided for a testee to stare at the target with his (her) eyes. F8. Forehead bearer The testee's forehead rests on the forehead bearer so that the position of his pupils is fied.
- Page 14 3.2 Description of rear panel Fig.3 B1. Battery Lid Move the lid parallel to change batteries. B2. Electronic Panel B3. Monocular Covering Knob The covering of the testee's right or left eye will be realized by turning the knob. B4. Compensating Ocular Key Sliding the key can make a +2.00D compensation for the diopter of eyes.
- Page 15 3.3 Viewed from the Measuring Window Fig.4 C1. Measuring Window Glass Testee sees through it to the green target. C2. Calibration Reference Mark It is used to check measurement accuracy. C3. Benchmark Hairspring When the optometrists use the device, they can slide the key and make the benchmark hairspring level at the reflecting light spot of the testee's pupils.

Page 16: Preventive Inspection
Fig. 5 4. Preventive inspection The operator should conduct preventive inspections before use. 1) The observation window and measurement window should be clean. 2) The numbers displayed on the display window should be normal. 3) Inspection cycle: before use every day. 5. - Page 17 *Properly dispose of the used battery to avoid environmental pollution. 5.2 Device Startup and Shutdown 5.2.1 Device startup Press ON/OFF key to make the start-up of the device initialized. The microprocessor in the device gets the position of pupillary distance pointers and then the data display on the corresponding LCD window.
- Page 18 d. The tester observes the reflecting light spot on the testee's pupil through measuring window. Slide the Left and Right Pupils Measuring Keys, the left and right pupillary distance pointers will coincide with the reflecting light spots of the testee's left and right pupils, respectively(as shown in Fig.7a and Fig.7b ).
- Page 19 easily and quickly, the tester should remind the testee to always stare at the green target in a level state, without moving his (her) eyeballs. 5.4 Measurement of Monocular Pupillary Distance a. When needing to measure the left or right pupillary distance, please turn the Monocular Covering Knob (as shown in Fig.3 B3) which can cover the other eye completely (as shown in Fig.8a and Fig.8b)
- Page 20 b. The optician makes inspection standing by the side of the testee, and the latter is preferably situated against the light. Place the instrument in the horizontal level (see Fig.9a), and target the guide mark at the top of cornea of the testee. c.
- Page 21 b. In such mode, moving F3 left measuring key is to adjust automatic power-off time, which will be shown on the screen (time range: 0.5-3 minutes with the 0.5-minute interval). c. Moving F10 right measuring key is to adjust LED brightness and the corresponding LED current value (the bigger the LED current value, the brighter the LED lamp shines) is shown on the screen.

5.8 Usage of Calibration Reference Mark Before using PD meter, we recommend you check whether the display value is normal and to perform “the inside check of PD 46mm”. Slide C3 Benchmark hairspring and make it coincide with C2 Calibration reference mark, if the PD is 46mm with left and right PD being 23mm respectively, it is normal. -
