The experiment file for Speed of Sound (activity 24) supplied with Logger Pro 3.1 and 3.2 is flawed. It collects data immediately instead of waiting for the sound to start.
To fix the file, enable triggering with a level of 2.6 to 2.8. Attached i...
We tested the 400x lens in 2005 and we decided not to carry it. Because of the high magnification, this lens has a very narrow depth-of-field, which makes it very difficult to use as a handheld unit. In our tests, anything above 200x magnification wo...
The LabNet Radiation Monitor sold by Pasco scientific can be adapted for use with the ULI. The plug on sensor is an RJ-11 plug, but the pin assignment on that plug is not correct for a Vernier interface. Pasco sells an adapter that switches the pin a...
Most of our products are created as a hybrid cd so that they can be viewed on Mac and Windows. The software that you use to copy the disk must be able to preserve both the Mac and Windows information when making a copy.
The best way to do this is...
Or, a broader question is "How do the data from the WDSS and Motion Detector compare? Both will display acceleration values."
The sync between the WDSS and any other interface is approximate, although it can be quite good. The WDSS has its clock; ...
The most common problem is that the power supply driving the light source is noisy, causing a 60 or 120 Hz flicker of the light level from fluorescent, incandescent, or other lamps.
Your eye does not pick this up, but the sensor will. You may be ...
The discussion below is based on tests done with a new-style MG-BTA with a rotating head in August 2006.
The whole issue of accuracy is pretty difficult to address. There is no one easy way to state it. We can talk about the resolution of the unit...
If you are using older probes, with DIN-BTA adapters (non-AutoID), you can get confused by changes we made in our Physics with Computers book. In early versions of Lab 25 (Ohm's Law) we suggested putting the current probe in channel 2 and then later ...
If you are running Word v.X or Word 2004, there is a problem in the way the Mac version handles images that contain transparency. According to Microsoft's web site, the problem is Apple's fault. According to Apple's web site, the problem is Microso...
When setting up for a remote data collection experiment, make sure that all probes are connected to the LabPro before selecting "Set Up LabPro" from the Remote menu. If you plug the probes into the LabPro after selecting Set Up, the proper calibratio...
