Question about Premiere Microscopes P-01310 Monocular Microscope

1 Answer

The small knob that moves the slideto the left or right on the platform (the one furthest from the observer) is slightly loose, and instead of rotating in a smooth circular motion it rotates rather ecliptically. Could this be causing our out of focus issue? The "organisms" on the slides come into focus when we lift slightly up on this know. Can the knob be replaced? If so, how would I know if this will fix the problem.

The knob you are talking about is called the x-axis control knob. It does not directly affect the focus. What affects the focus is the slight manipulation of the stage and or slide while you are adjusting the x-axis control knob. It only takes the slightest pressure to throw the focus off very far. Theoretically you could completely remove the specimen holder and move the slide around with your fingers.
The specimen holder may need to be replaced but without further more detailed knowledge of the mechanical problem I cannot instruct further.

    Tip

    You Just Bought an EQUATORIAL Telescope Mount!


    Even though we warned you not to do this, you bought one anyway! Beginners should never buy an EQ telescope mount as their first telescope. It's too late now; so I guess we will need to teach you how to use it!

    Equatorial mounts move in a way that seems not to very intuitive. Unlike the easy Alt AZ mount which moves up and down and left and right, the EQ mounted telescope seems to move in TWO dissimilar directions at the same time.

    Additionally you must first polar align the mount on the North star Polaris before you can use it. SEE! we told you not to buy it!

    Here are the steps to roughly polar align the telescope so you can use it. If it is motorized the single Right Ascension motor will keep the sky object inside the eyepiece for long periods of time. If you do not have a Right Ascension motor, the slow motion RA knob can be slowly turned to keep the sky object centered in the eyepiece.

    Begin by leveling the mount and tripod. Move the entire mount and tripod so it is pointing roughly to North, as close as possible using the steps below or a compass. Don't forget to adjust for your magnetic deviation. My location's compass reading is about 5 degrees away from true North. This is called magnetic deviation. You can find your location's deviation on the internet. Then proceed with the steps below.

    First, adjust the Declination to the latitude for your observing site. Declination is the angle that the scope is pointing UP, and it's the same as your latitude. For example Dallas, Texas is about 32 degrees North latitude, adjust the scope so the small indicator reads 32 degrees. By the way, the North star in Dallas, TX is about 32 degrees above the horizon. Your latitude matches the elevation of Polaris (the North star) above the horizon.

    Second, either look through the polar alignment scope buried in the axis of the telescope mount, or look along side the axis, and get the star Polaris lined up in the cross-hair of the polar alignment scope, or as best you can by looking along the side of the mount axis, or lining it up using your compass.. This will put the scope to within about 3/4 of 1 degree of the TRUE North celestial sphere. This is good enough for VISUAL observation, but NOT good enough to do astro-photography..

    Adjust the DECLINATION up or down, and move the entire mount left or right until you can see Polaris as indicated above, or it is lined up as close as possible.

    Now you are roughly polar aligned. Now you can move the tube around by loosening the Right Ascension lock, and or the Declination lock until your sky object appears in the small finder scope mounted on top of the main telescope tube.(DO NOT MOVE THE MOUNT, and the counter weight should never be higher than the telescope tube) Lock down the scope in both axis and use the fine adjustment RA and DEC knobs to center the target. Again, DO NOT move the mount or tripod. The mount should still be pointing at Polaris.

    This web site illustrates this procedure:
    http://www.astronomy.net/articles/4/polaralign.html

    also this web site

    http://www.telescopes.com/telescopes/polaralignmentarticle.cfm

    You should be able to keep an object within the field of view of the eyepiece by slowing turning the Right Ascension slow motion control knob-------- IF you are actually accurately polar aligned. Small adjustments may also be needed with the DEC slow motion knob since you are not exactly polar aligned using this rough alignment technique.

    However it can be used successfully for visual observation. Your scope will now track the motion of the stars as they move across the sky.

    Hope that helps you!

    Clear Skies!

    How do I add thread to the bobbin


    The small box you will turn towards you while you hold the big handwheel. It might me very tight but it isn't going to break by turning hard. Tighten the small screw before you begin. When it is loose you can wind your bobbin.

    Filter Knob and Buttons move from left to right


    If you pull the knobs off, you will find lock nuts under them. You could tighten them up. See if the knobs have set screws on them to lock them in place before pulling them off. On Allen & Heath, I don't think they do but, just in case.

    Picture is small box upper right hand side


    when picture is getting smaller in size or goes away or moves towards one side ( like yours) then hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some CRT computer monitors & CRT TVs on main board at some soldering joints crack develops....then due to loose contact picture becomes small in size or disappears ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears for some time............so solution is ......TV main board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re- soldered ...100% it works again................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer

    We have a 2005 f150 king ranch v8 5.4L with center console shifting that will not shift out of park. We moved the truck and put it in park. We changed rear brakes and rotor on the right side. We get in...


    SO you didnt have any problems before the brakes ..right. How does the top of the shifter feel? does it feel like its lifting the lock or does it feel like its not doing anything. I had one of these in yesterday that the screw holding the shifter knob came out. You have to take the knob off and be careful not to lose that screw. Lower the leather apron and then the slide the chrome trim down. There may be a small spring thats loose also. if you find that you can get it back together, one thing is that the spring goes on the very top of the shift rod, and there is a little lever that LIFTS the rod (throught a small slot) dont know if you need to take the trim off the knob or not, but if you do, there is a small white plastic piece at the base of the knob (back side, size of your fingernail), you need to pull this down/out to take the trim off. Dont lose it.

    Russian Lomo (Biolam?) old monocular-coarse focus wheel slippage


    The right hand shaft knob contains the coarse focus locking clutch adjustment mechanisim( big name-simple design). This solution applies if you have the model with the fine adjustment wheel mounted in the base and may or may not apply if your fine focus is in the left-hand knob.

    Inside the right hand knob ( as viewed from the rear of the scope) is a threaded disk/nut which has two pins (Slightly and for reasons I don't understand: they are offset vertically, they have different pin diameters and different pin lengths) In theory, they lock into the bushing within the knob proper to keep tension on the clutches while keeping the knob from falling off.

    The repair can proceed in two ways depending on if the disk/nut has totally been unscrewed from the focus shaft.

    Gently pull the left knob and as you do turn it slowly to see if the pins reseat. If they do you'll feel a slight lurch outward of the knob. Hold gentle outward tension( so as the pins remain seated) as you turn the knob clockwise until the slippage in the clutches is so lessened that your knob is firm and the focus adjustment is operating to your liking.

    IF that didn't work it is likely that the threaded disk/nut has come off the shaft and will need to be reset and screwed back down. The disk is easily cross threaded and you'll need tweasers or micro plyers or a hemostat and/or a flat headed finishing nail. Plus I recommend a small bottle of LOC-TITE(tm) semi-solid thread sealer--NOT the kind that freezes the threads

    As you unscrew the knob counter clockwise pull on the knob to slid it off the shaft it should come off in your hand revealing about 6-8 washers on the shaft. These are the clutches so be careful not to loose them.

    The knob should have a slight rattle and that is the disk nut. To get to the disk/nut put a small finishing nail head first into the shaft whole and push to release the plastic knob insert cover out being careful to not loose the disk/nut.

    To clean the threads and insure an easier repair screw the disk onto the focus shaft to insure the threads are clean.

    This next part works better with the scope lying on its left side.

    This part is optional but not necessary to get the scope back in operation. Place a tiny amount of LOC-TITE thread sealer on the shaft threads. This will make the knob clutch adjustment more stiff but will also reduce the likelihood that the knob will be adjusted out too far again. The loosening occurs when the knob is turned before the operator realizes the pinion gear limit has been reached or by someone who dosen't understand correct opperation of the focusing assembly.. So long as the clutches are engaged the and there is no slack in tension the disk/nut shouldn't come off the shaft again.

    Observe the pins in the disk/nut and match them up with the holes in the aluminium/brass knob bushing. You'll have to wiggle the disk around to get it reseated properly. Once you do, hold the disk firmly against the bushing to keep the pins seated as you put the knob back over the shaft, pushing it all the way down against the shaft.(The clutches are springy so don't worry about it locking in place just now).

    You may prefer to hold the disk/nut and knob firmly with a finger and spin the left hand knob counter-closkwise for easier threading of the nut but remember this will also move the focus arm. Not a problem if you start with the focus in the range centered.

    If using the right knob: Turn the knob clockwise feeling for the threaded shaft maiting back up with the threads. IF it cross-threads, back it off try again. Once the threads are engaged keep the outward tension on the knob so the pins don't slip out. When you/ve screwed it down far enough, the clutches will take up the slack and keep the knob from slipping away from the disk/nut. You'll know the clutches are engaged when the focus shaft turns.

    If you are happy with the repair slip the knob cover back on and snap in place. It if falls out place a little of the thread sealer on the rim and try again.

    If you like this solution it took me an hour to write it up. Please consider volunteering an hour with a local non profit. I support the American Red Cross, Habitat for Humanity and the USO.

    Cursor only moves left to right


    This device is monitored via a kind of strain gauge; that is why it does not seem to move; it does move but not noticeably.
    If it is no longer responsive in one or the other direction, I would call it dead.
    I have never seen one of these loose but I would expect to find a small sealed housing that has an equally small, multicontact connector attached.
    If you are unlucky, Toshiba may have attached this to the keyboard's platform requiring the replacement of it as a unit.

    On most laptops, the keyboard is fairly easy to remove and if you can accomplish that, restoring the truncated joy stick is probably not difficult.
    Sorry I cannot give you detailed instructions for disassembly.

    If the rt guide arm is not moving fully forward, just put a couple of drops of white grease on the mechanism.

    The arm with the felt pad is the autu-head cleaner pad. after a year or 2 of use, it will be more a menace than a good useful cleaner, as it will add the accumulated dirt on to the head, instead of cleaning. Just remove it.
