When turning on the Rotating Mirror, it is normal for your image to disappear initially. There are some steps you can take to get it back again. We've found trying the following steps help find the image: - Ensure your microscope lenses are clean. Use a Kimwipe, or some other lab-grade wipe to make sure you do not scratch the lenses. Smudges can make your image blurry and more difficult to find your image. - Ensure that once the mirror starts rotating that you remove your polarizer. It is safe to look into the microscope without them as long as the mirror is spinning. If you leave them on, the image might be too dim to locate. - Reduce your diffraction patterns as much as you can, as the image can be hiding within them. You can do this by turning Lens2 slightly askew so it is no longer quite at a right angle to the beam axis (should only be 1-2 degrees). This might seem like it will mess up your alignment, but in reality, it should “darken” the diffraction pattern in the background of your viewing window without darkening the image you’re looking for. This can reveal your image that could have been hiding in plain sight. - Adjust the micrometer knob (not the beam splitter knob) to scan back and forth in case your image is just out of view. Maybe take note of what the knob’s position is before you start moving it so you can always return to the start. - If you’ve tried all of the above with no luck: adjust your microscope lens in various ways by picking it up, rotating it, or jiggling it within the holder and see if your image “pops” into view. - As a last resort, you may try ever so slightly adjusting the beam splitter knob, but you really shouldn’t move it too far in either direction. If you move it too far, it may be impossible to get it right back where you had it when the beam was aligned while stationary.

Glad you like them!

Most graph analysis tools apply to only one measurement and run at a time. If you have multiple plot areas, you can turn on an analysis tool for one measurement's run, make another measurement's run active by selecting its symbol in the legend, and then turn on an analysis tool for it. There is one graph analysis tool that can be used across measurements and runs to find coordinates. The Multicoordinate tool is demonstrated in this video: ua-cam.com/video/naCvuMbQYPU/v-deo.html.

In our testing, the downloaded SPARKvue PWA is working without an internet connection. After you install it, you should find a shortcut to launch it using its locally cached files. Does that work for you? If not, please contact our Tech Support group for help troubleshooting: pasco.com/support. It appears that the Ctrl+F5 command you cite is a request to ignore the local cache and download all the files again. It sounds like that would require an internet connection.

Yes, you can link the scaling of multiple y-axes. Here's a new How Do I video demonstrating how: ua-cam.com/video/S0I1ev8gv4U/v-deo.html Thanks for your question.

thank you!! very useful!@@pascohowdoi

Educators in the US can find the price of the Smart Times Photogate System on its product webpage at pasco.com/product/ME-8932. Outside the US, please contact your local PASCO representative: www.pasco.com/support.

Although the video doesn't demonstrate this step, you would click on the name of the QuickStart experiment file to open it. The sampling mode (continuous, keep, etc.) will already be set appropriately for that experiment in the file.

You are correct that the video demonstrates exporting each run to a separate csv file. If you'd like to export multiple runs at once into the same csv file, press the Comparison Mode button before exporting. The Comparison Mode button is explained here in the Spectrometry online help system: help.pasco.com/spectrometry/getting-started/analyze_light_page/.

Thanks for your comment. As an alternative, our Discover Free Fall System (ME-9889) does have a magnetic drop box, though the release switch is still wired to the drop box: pasco.com/product/ME-9889.

@@pascohowdoi A magnetic drop box is not an option for me, because I want to demonstrate that the equivalence principle is wrong, and for that I need to use spheres made out of many different materials, most of which are not magnetic.

Please see the relationship developed in the instruction manual, which you can find in the Documents section of the product page link in the video description. Thanks.

We don't have the data file from this video recording, but you can find sample data for this experiment in the PASCO Capstone sample data file here in our Experiment Library: www.pasco.com/resources/lab-experiments/492.

As of PASCO Capstone version 2, the alignment option is still available, but it has changed a bit visually. You'll now see the alignment options to the left of the coordinates box as a graphic of concentric black and red squared (instead of as a drop-down arrow to the right).

Please contact your instructor or IT for your school's access code, or get in touch with PASCO Tech Support for assistance: www.pasco.com/support.

It doesn't work, I made this solution and my PH meter failed within 2 months and I had to replace it. I recently made a 4mol solution that requires 29.82g KCl per 100ml 4.00 buffer solution.

We've just updated the description with corrected links to the PASCO product pages for the pressure tap and a variety of pressure sensors. If you're outside the US, you can find your local PASCO partner at www.pasco.com/support. Thanks for your interest.

Thank you and thanks for your question. Yes, you can use any data set, including user-entered values to define the height of error bars using the error bar type "Measurement". Here's a video demonstrating this: ua-cam.com/video/XJs0B4HBmhg/v-deo.html.

@@pascohowdoi Great, thank you!

"Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste."

Thanks. If you still have the documentation that came with your Dissolved Oxygen Sensor, you should be able to find information about the polarographic filling solution there. We no longer sell this type of electrode, so we don't have an active webpage for it with documentation, but you could contact our Tech Support folks who should be able to track it down for you: www.pasco.com/support.

A sleeve can be used multiple times, as long as it's still intact.

Thanks for your interest. Within the US, you can find US educator pricing on the product's webpage at pasco.com/product/ps--2225. Otherwise, please contact your local PASCO representative for pricing information via pasco.com/support.

Can Pasco help?

Please note that the PASCO Python package is not compatible with the PS-3200 AirLink. The supported wireless sensors are listed on www.pasco.com/downloads/python. Please contact PASCO Tech Support if you'd like troubleshooting assistance: www.pasco.com/support.

We did successfully test our sample code (github.com/PASCOscientific/pasco_python) and example projects (github.com/PASCOscientific/pasco_python_examples) on the Raspberry Pi OS flavor of Linux.

@@pascohowdoi unfortunately, many devices run with AirLink (e.g. a light sensor and a pressure sensor can share the airlink device). This connection was chosen due to the demand of my university. However, the absence of connection/support of AirLink to development/teaching becames a drawback and new devices aquisitions will be refused due to the technically support. Other brands will be probably choose.

@@rikardos17q For now we support only the Wireless Sensors shown on our Python page at www.pasco.com/downloads/python. I'll pass along your interest in support for PASPORT Sensors via the AirLink, but we have no current development plans for it. By the way, we've updated the PASCO Python module to version 0.3.50 to address the ModuleNotFoundError. If you're interested, please give it a try on your Linux device to see if it resolves that error you experienced.

Hi Ricardo. Please note that the PASCO Python package is not compatible with the PS-3200 AirLink. The supported wireless sensors are listed on www.pasco.com/downloads/python. Please contact PASCO Tech Support if you'd like troubleshooting assistance: www.pasco.com/support.
