Page 2: Classification
Introduction Dear User： SW-1000 is a precise ultrasound measure instrument, designed for detecting axial length, depth of anterior chamber, thickness of lens and calculating the IOL. This User’s Guide is designed as a training and reference manual. We recommend you carefully read and follow the steps in this guide to ensure that the machine would have optimum performance. -
Page 3: Precaution
Precaution This instrument requires the power supply of AC 90~230V ， 50HZ±2%. The power socket indoors should have ground line. If the local power net could not fit the requirement, then we recommend you to use regulated power supply. Improper power supply may cause instrument damage or person injury. -

Page 5: Theory And Function
Theory and Function Ophthalmic A scan SW-1000 is composed of main unit, probe, pedal and so on. The probe contacts the cornea and sends out ultrasound of 10MHz. The echo wave from front surface, back surface of lens and retina is detected. The signal is processed and then we get the depth of chamber, thick of lens and axial length. -

Output：IOL calculating table; Measure：Anterior chamber, lens, vitreous body and total length. Curve freezing：Manual/Auto mode, controlled by pedal; Output：Build-in fast thermal printer; Display：Color liquid-crystal screen; Input: touch screen. Power: 30W Environment Requirement 1. Work Environment Ambient temperature：+5℃ ~ +40℃ Relative moisture：≤ 80% Power Supply：AC 90~230V，50×（1±2％）Hz Keep away from strong magnetic or electronic field. -
Page 7: Install And Connection
Install and Connection 1. Check the package to see if anything missing. (Reference to Appendix: package list) 2. Insert probe, pedal and power plug to respective socket. （See Pic.3） Align the salient on the probe connector to the gap on the probe Pic.3 Pull and plug the probe socket, and plug it in. -
