Distance index & scale on 100mm f/2.8 L

Once development manual of the EF 100 mm f/2.8 L USM macro lens (or no matter what lens, incidentally), is recommended in order to align the distance index | periods on the scale of distances (e.g. 0. 30 m) or by central semicolons of reports of magnification (e.g.:1: 1)?

The difference may seem subtle, but it's important when Imaging (and then measure and calibration of the rungs of the ladder) of tiny subjects.

-L

Hello lwalker,.

The infinite position on this lens where the vertical line of the "L" mark is aligned with the distance to the scale indicator.  To better focus should always check through the viewfinder or Live amplified View.

    Someone knows why? The two PCs have the latest drivers and all the Windows updates available. Both are running Vista Ultimate. If something I expect the scores to be the other way around!

    Hello

    The functionality of Windows Vista experience Index that is designed to help better understand
    How Windows Vista and other software will perform on your computer.
    As I know the Windows experience index scale varies from 1.0 to 5.9.
    A higher base score means that your computer run better as a computer with a lower score.

  • How can I change the scale when you measure the distance?

    When you measure a distance of 20 m on the pdr-drawing tool says 10 cm measurement. How can I change the scale? The notice said it's possible, but I don't know how I do

    Hi Bandreason,

    How to change you can visit this link: Adobe Acrobat x: change the measurement scale. ROCKY MOUNTAIN TRAINING blog document is for mac but option is the same.

  • The distance between the objects and not the objects themselves scale

    I work with a card and who is currently around A4 in size but will print about A0, cities are so numerous that they overlap on the small map. I hope that there is a way to change the positions up to size without scaling objects in this way, they must not overlap into the completed task. I use illustrator CS3.

    Jim,

    Before experimenting, always save a copy of the but not destroyed work.

    Have you tried:

    (1) to select the entire document (what you want to have at the present time, or relative, different size), possibly through selection > even > what is relevant, then object > transform > transform each uniform scale to the relative scale reduction (6.25% if you want to keep the size A4),

    (2) to select the entire document and scale up to 1600%?

  • Satellite A300-1MC PSAG8E - Win 7 will forge index

    PO10220 BIOS update reduced WEI

    Hello

    I have Toshiba Satellite A300 1MC (PSAG8E) 5.
    To improve performance there a few weeks, that the Vista Home Premium has been replaced by Windows 7 Home Premium.
    Until it doesn't index performance Windows was 3.7, but after installation, it has been reduced to 3.2.

    That's why & what can do?

    In my desperation I found on the Web of Toshiba site that PO10220 the BIOS update would improve performance.
    There is a warning window of the unknown publisher that I have downloaded the update.

    The result was that WEI has been reduced to 3.0 (which are pretty low).

    Why is he past & what can I do?

    Hello

    You have changed the operating system from vista to Win 7.
    The two systems are different and so the Windows experience index is different
    This is nothing unusual.

    In Windows 7, the maximum score is 7.9 (and 5.9 for Windows Vista users).
    While these numbers may seem strange to those used to a scale of 1 to 10, the Windows team has established the numbers for a reason.
    As technology becomes more sophisticated, the index will extend to 8.9 or beyond, to accommodate the faster hardware.

  • Chart with multiple scales of Y

    Hello

    As you can see in the excerpt, I'm trying to plot a graph with several scales of Y. What do you think is wrong with it to get the following error.

    Possible reasons:

    LabVIEW: invalid property value.

    I wouldn't change nothing to indexing.  You already wrote this code.

    I clicked the balance you already had and clicked on "Double ladder" to create the second and third.  Once they have existed, the crux of your property has worked fine as it was.

  • Count the edges of the 2 signals TTL (Heidenhain linear scale)

    Hi all

    This is my first post here. :-)

    Currently, I'm doing a VI to be used with a linear scale. The linear scale gives 2 TTL signals that have an offset of 90 °. The change in distance of the linear scale is given by counting the fronts and edges of the two signals. See the following image: Ua1 is signal 1 and signal 2 Ua2. You can ignore the other signals.

    Now, I want to count the 4 edges in order to translate the 2 signals in the distance. This means that I need advanced two counters for Rising-rising, Rising-Falling Falling Falling, falling on the rise for 2 signals. I tried to do 4 points two counters in LabVIEW but that of course does not work, because an acquisition of data can access the card TTL or I did it wrong.

    Once I have to handle this, I also want to understand the meaning.

    My card TTL: NI 9402

    My electronic Heidenhain interface: 100 IBV (http://www.heidenhain.com/fileadmin/pdb/media/img/598_160-23.pdf - also at the origin of the image)

    Hardware configuration: linear scale-> IBV (Elektronic Interface)-> NI 9402-> LabVIEW

    Signals: Analog 3-> 3 TTL-> OR 9402

    I hope I do not double post. Any help would be greatly appreciated.

    I used Heidenhain linear scales in many applications.

    As stated in the previous post, the output of your balance is as a quadrature encoder. Therefore, you must use an entry of the DAQ card counter to measure the position of the scale.

    The desired X 4 mode is done by the meter itself (not possible with some old maps of OR).

    As starting point, see measure angular Position.vi that comes with examples of LabVIEW. On your linear scale, change the type of the polymorphic DAQmx create channel VI CI linear encoder and etiquette of pulses per revolution at a Distance by pulse.

  • How to index a table on multiple sites?

    Hello

    How to index a table on multiple sites?

    I searched this issue and was not able to find the answer. I understand that it can be done with loops, but I don't know how.

    I use the detector of crete vi for frequency domain data collected a VNA (s2p) file. The products contain a table of amplitudes and a table of locations. The problem is that the locations refer to the index of table of amplitude, which is not the same as the frequency. My idea is that I can use this output of the places table to index the frequency to the detected peak frequencies table and then draw these, as well as some analysis data and manipulation on them. Currently, I can do this only by consulting table on the front panel.

    The entrance to the peak detector is currently a table 1 d of the scale (what is the problem?).

    I also looked at the supply frequency & estimate VI, but this VI seems only exit of scalar data for the largest peak, not exactly what I'm looking for.

    Thanks for your help.

    You have a second table for the tested frequency?  If so, then you are right that you just need to index this table with the indexes by the Ridge detector.  Use a loop for.  Automatic index to the index, use index in array to get the value of the frequency and autoindex on frequencies.

  • Time scale does not properly after separation of the two signals of virtual channel

    Hi all

    I have a problem when I use a virtual channel with two analog inputs. I'm cutting the two signals into two separate tables of waveform, as shown in the attachment. The two signals seem to be reading very well, the problem is that the time scale (x-axis) begins to act on the strange. Seconds displayed time seems to keep jumping up and down at a high frequency, resulting in the two signals of displayed does not correctly in the table of waveform. Could someone please try to help me? Any help would be greatly appreciated!

    Thanks in advance.

    Try to acquire a signal with first time information. You can replace the DBL 2D with a data type of 1 d wave. You don't need this code extra silly - just a function of Board Index to get the separate channels.

    Hello

    I have some problems with a graphic.

    The problems I have:

    1. the time is not correctly displayed in the graph (allways 02:00:10 instead of the current time)
    2. the data points in the table have a distance of 1 s (x-scale). This is not correct.

    With all the tips I gave you above, I have no idea what you were doing. But, if you reloaded the OS and also reload all your modules, that could be the culprit. A clean reload of the OS only, let it run for a week, really is the best way to check.

    I have not marked as correct answer because it is not related to what you have actually done, which has been reset to the scale. Your problem seems to come from having defined preference generally by climbing, adjust the percentage.

  • The distance between objects, maintain ratios

    Im trying to increase the height of a drawing on illustrator, while keeping the individual components exactly the same thing. To the point of discussion saying theres four rectangles, one above the other... I want to increase the distances between each rectangle while maintaining the same ratio of distances. I don't know if this is even possible, but pointers are appreciated!

    Basically, you will first need to enlarge the complete drawing by the desired amount.

    Then do the math to calculate how much you would need to scale down in order to have the same size.
