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...
A macro or shortcut for the F11 key on your machine will prevent Logger Pro 3 from starting and stopping the data collection using that key, because the computer OS will intercept the keypress and Logger Pro will never get the information.

Placing your specimen slide on top of a small fluorescent lamp will provide even, cool back-lighting. A light table used for slides works well. Overhead projectors, generally used for transparencies, can also be used. Place a piece of white paper o...
- Always quit the data collection program gracefully before removing the LabPro from the computer or calculator. When the program quits, it turns LabPro off. If you do not do this and you just disconnect the cords and put the LabPro away, it will st...
During data collection, it is possible that EasyData App will quit if the battery level in the calculator gets too low. The power required to collect data with an EasyTemp or EasyLink is greater than that needed for normal operation of the calcula...
