The trouble is the surge of current which fires the motion detector. In the old days, when computers were slow, there was enough time between the firing of the motion detector and when the force sensor was read that this was not a problem. Now comput...

The TI-73, 82, 83, 85 only have enough memory available to load one of the Vernier program groups at a time. The TI-86, 83+, 89, 92, 92+, Voyage 200 have enough memory available to load all three programs. If your calculator is currently full, you w...

Unfortunately the answer is No. The LabPro only works with the Logger Pro software. Since Logger Pro is designed to run on a Pentium, Power Mac or newer computer, that means that LabPro must also do the same. If you have a an older computer, you ...

The problem is that the PHDERIVS program deletes four list variables from the calculator's memory, and the DataMate program then tries to utilize these lists. The most recent CBL 2/LabPro operating system update takes care of this problem. See Ho...

Some sensors require a brief warm-up time before they take their reading. We made LabPro and CBL 2 smart so that when they were using AA battery power, they would power up before they take their reading, take their reading, and then go back to sleep ...

Actually there are two ways of storing data with the Datamate program, both of which are described in the Datamate Guidebook, available for download from the following address: https://www.vernier.com/calc/index.html 1. Saving data in your calc...

If you find that the radiation monitor works normally, but quits working when you start using a DCU (Digital Control Unit), it is because the DCU software is taking over the digital lines and setting them up to be used for output from the LabPro inst...

There are two switch settings on our Magnetic Field Sensor: Low and High. High means high sensitivity, low means less sensitive. For experiments involving household appliances, you definitely want the High setting. When opening an experiment file in ...

When we designed ChemBio, we anticipated that most chemistry and biology teachers would want to see a live graph, so we force the program to produce a live graph, which requires time intervals longer than 0.1 s. It is possible to trick the progra...
