Getting Started
•Install a single AAA (alkaline or NiMH) battery. A low battery (0.9 –0.65V) is indicated by intermittent illumination flicker.
Illumination level is unaffected by battery voltage. If a rechargeable battery is used, it must be removed for charging
elsewhere. Alternatively, power externally using the supplied USB cable. When powered via USB, illumination of the
microscope is on permanently.
•Select a screw-on connector adaptor to match your application. The adaptor must match both the connector polish type,
e.g. PC or APC, and ferrule diameter, typically 2.5 mm or 1.25 mm. The unit comes with a 2.5mm PC Universal Adaptor.
See Optional Interchangeable Connector Adaptors section on last page for other available adaptors.
•To inspect a fiber connector end-face, push the connector ferrule into the microscope adaptor, so that it is positioned
against the end stop. If inspecting an APC connector using a Universal Adaptor, rotate the connector, so that end-face is
flat, or focussing will be poor. However, it is recommended to use APC adapter with specific connector type as a better
solution where possible.
For the case of MPO adaptor, adjust the screw attached to the adaptor to move connector ferrule laterally to inspect all
fibers on the ferrule.
•Press the front switch of toggle button to select coaxial illumination (see below). To select (green) oblique illumination (see
below), press and hold the front switch of toggle button. Coaxial illumination uses a white LED on the side of the scope
body. Pressing rear switch of toggle button will turn off instrument. For convenience and battery saving, illumination stays
on for about 2 minutes; however, timer is disabled if using external power for bench use.
•To focus, while holding the rubber eye cup to your eye:
- adjust the focus knob to achieve a clear image of the connector tip. When image is in focus, the centre of XY-alignment
wheel (right) will typically be positioned near the white arrow on the right of focus knob.
- adjust the X–Y adjustment wheels to centre the image.
If you find it difficult to locate and centre the image, do the following (much easier with a very dirty connector!):
- loose X-Y adjustment wheels and move them to find the edge of the connector
- from the edge of the connector, project to the centre of the image, which will be the centre of the connector, and rotate
X-Y adjustment wheels to move the image along projection path to this point.
•To illuminate a patch lead core, position and hold ferrule tip (at the unconnected end of patch lead) onto the white LED
located at the side of microscope, and use the coaxial illumination mode. See sample image in Fig. 1 below.
•For convenience, the microscope can be mounted on a standard camera tripod (Fig. 2 below), or a wrist strap fitted to assist
carrying.
•It is good practice to use the microscope with both eyes open, to avoid eye strain. The rubber eye cup helps this.
•To view and/or save microscope images on a computer, replace the scope’s eyepiece with a digital camera (optional, see
Optional Accessories section on last page) connectable to a computer via USB.
Illumination Explanation
The microscope has triple illumination capability, each with different attributes:
•Coaxial: White LED light hits the fiber end-face at right angle, providing the highest level of image details.
•Oblique: Green LED light hits the fiber end-face at an acute angle, which makes the fiber core readily visible, but allows users
to see only major defects and contaminants, with minimal training.
•Core: White LED light travels up the fiber core to show continuity or sub-surface fiber core defects.
