STRUERS PSM-10 (01) PDF DOCUMENT

The packing for the STRUERS PSM-10 includes the following items:

1 PSM-10 (Portable microscope)

1 Eyepiece 10x

The STRUERS PSM-10 is designed for use in the field and is suited for on-the-spot examination of large objects during both the building and the operation processes. It can be used both on external surfaces and in corners, cavities and tubes.

The STRUERS PSM-10 can also be used to control structural impressions, carried out with Transcopy or RepliSet.

The STRUERS PSM-10 microscope is supplied with a sturdy aluminium transport case. For proper transportation and storage, please follow these guidelines:

• Keep the parts safe in the case when not in use.

• Keep the delicate objective lenses in their special carrying case when not in use.

• Use the protective caps supplied with the microscope when not in use.

The main components of the STRUERS PSM-10 are:

① Eyepiece 10x in the eyepiece port

② Focussing ring

③ On/Off switch for lamp

④ Lamp housing (LED light bulb and battery)

⑤ Tripod base – Low (standard)

⑥ Objective lens 10x

The STRUERS PSM-10 is supplied with a tripod base mounted. A Tripod base for curved surfaces, a round base for use on flat surfaces and a magnetic cross table with magnetic clamps are available as accessories.

To replace the base:

• Loosen the 3 Allen screws securing the base and remove the base.

• Fix the new base in position using the Allen screws.

• Remove the protective cap from the objective port.

• Insert the objective lens and screw firmly into place. Take care not to touch the lens with your fingers.

• Remove the protective cap from the eyepiece port.

• Insert the eyepiece into the eyepiece port.

• Take care not to touch the lens with your fingers.

• Secure the eyepiece by tightening the eyepiece locking screw.

Note: When holding the microscope, take care that the eyepiece doesn’t fall out if the microscope is tipped.

• Place the microscope over the point of interest.

• Switch on the lamp.

• Move the microscope until the spot of light illuminates where required.

• Use the focusing ring to focus on the point of interest.

Note: Take care that the objective is not damaged by touching the sample.

Tip: Remember to switch the lamp off after use.

With the magnetic cross table secured on the STRUERS PSM-10:

• Place the table in position on the surface.

• Flip the levers on the magnetic cross table down; this will engage the magnetism.

• Use the X and Y positioning knobs to position the field of view directly over the point of interest.

To release the X/Y table:

• Flip the levers on the magnetic cross table up; this will release the magnetism.

If the STRUERS PSM-10 is to be used for examination of structural impressions (e.g. Replicas made using Struers’ Transcopy or RepliSet), these must be glued onto a slide and then placed on a table with the structural surface uppermost. The microscope is positioned above the replica, which can be moved for viewing.

The graduations on the measuring eyepiece should be calibrated for each objective lens using a Plate micrometer (accessory). To calibrate:

• Remove the eyepiece and replace with the measuring eyepiece.

• Place the Plate micrometer under the microscope and position so that the text on the plate is directly under the spot of light.

• Use the focusing ring to focus on the text.

• Move the Plate micrometer so that the graduation scale is centred in the field of view.

• Turn the measuring eyepiece until the graduations are lined up with those on the plate.

• Measure the distance between the graduations on the eyepiece (the distance between the graduations on the Plate micrometer is 0.01mm).

The distance between the measuring eyepiece graduations should be re-measured whenever the objective lens is exchanged.

After calibrating the measuring eyepiece, follow these steps to measure:

• Remove the Plate micrometer and position the microscope over the point of interest.

• Measure the distance of interest using the graduations on the measuring eyepiece.

Please refer to the LCD Digital Microscope Camera Instruction Manual to familiarise yourself with the camera and its operation. For initial setup:

• In the SETUP menu, set the Exposure and White Balance [EWB] to Auto [A].

• Fit the adaptor onto the camera.

• Remove the eyepiece from the microscope and slot the adaptor into the eyepiece port.

• Secure the adaptor to the microscope with the locking screw.

Tip: The microscope will be top-heavy with a camera mounted. Take care that it doesn’t tip or fall over.

• Connect the power supply (AC power adapter or Movipol-5/Transpol-5 battery pack) to DC IN on the right side of the camera.

• Insert an SD card.

• Press the POWER button.

• Press the On/ Off switch on the PSM to turn on the lamp.

• Focus on the point of interest using the focussing ring.

• Press the SNAP button to capture an image.

Tip: Use the USB Shutter Cable and the remote controller supplied with the camera to eliminate vibration of the camera/PSM whilst capturing images.

In some cases, the image will appear bluish. To avoid this problem:

• Press the MENU button to enter the SETUP menu, then select Exposure and White Balance [EWB].

• Press the RIGHT button to enter the submenu.

• Select Manual white balance and press the Confirm button.

• Press the MENU button again to exit.

• 4 sliders (green, blue, red and white) will be displayed.

• Select the blue slider. Use the LEFT or RIGHT buttons to manually adjust the blue colour balance.

• When the desired setting is achieved, return to the SETUP menu and set the Exposure and White Balance to AUTO.

To ensure correct measurements using the Struers camera option, the magnification of the camera adapter must be known. It can be calculated with the use of a plate micrometer and a reference microscope.

• Capture an image of a plate micrometer using the 10x objective lens.

• Import the photo using Spatial Calibration in the Scentis software (or equivalent calibration software).

• Measure the pixel equivalent of one millimeter to obtain value “A”.

• Use a reference microscope with known magnification e.g. 100x to capture an image of the plate micrometer.

• Import the second photo to the calibration software.

• Measure pixel equivalent of one millimeter to obtain value “B”.

• Use the reference microscope with a 50x magnification¹, to obtain the pixel equivalent of one millimeter at 50x magnification, value “C”.

• Insert “A”, “B” and “C” in the following formulae:

A x 100 / B = D1,

A x 50 / C = D2

• The average of D1 and D2 is the magnification of the camera adapter² (this value will be approx. 6.5).

¹ Going from 100x to 50x magnification does not exactly halve the number of pixels. Thus, to balance the deviation, a calibration is performed at both magnifications on the reference microscope.

² Multiply this by 10 (10x objective lens on the portable microscope) to calculate the total magnification of microscope + adapter.

• Clean the body of the microscope with a soft, dry cloth.

• Should the body of the microscope become dirty, clean with a soft cloth moistened with mild soap solution.

• Do not touch the lenses with your fingers. Should the lenses become dusty or dirty, clean with lens tissue paper and a small amount of Ethanol or Propanol.

Important: DO NOT disassemble the microscope or the lenses. Service and repair of the microscope should always be performed by a qualified technician.

• Remove the lamp housing.

• Carefully remove the battery, unscrew the spacing ring (insert the special key to fit onto the slots of the spacing ring, and turn) and remove the bulb.

• Insert a new bulb, holding the bulb with a piece of lens tissue paper.

• Replace the spacing ring and the battery (with the text on the battery facing outwards).

• Finally replace the lamp housing and screw securely into place.

Important: DO NOT disassemble the microscope or the lenses. Service and repair of the microscope should always be performed by a qualified technician.

Store the microscope in the transportation case and keep in a cool and dry place.
