I seam to be having trouble downloading lightspeed. my computer thinks its a virus and removes it and a window pops up saying you do not have the permissions to download this program. im quite confused with this lol
Alex2893, Deja Vu! Boy, that takes me back. Do you happen to have Norton internet security? If so, you need to right click on the Norton logo, and turn off the firewall and the virus protection for about 15 to 30 minutes. Then download your Radiant Lightspeed. Pin that to your task bar in desktop, then you will need a program to open the driver package. I think I used "Wizard Tool" something or other. You can open the drivers but find a place to keep them as you will be doing this again. take my word for it. Good luck, Paul
i managed to download it and connect my meter to lightspeed but i cant get it to say 0.00 mw. its blank where its supposed to read it. it says i need to zero the meter to get 0.00mw to appear but when i click zero nothing happens
Alex, it sounds like you haven't loaded the driver package, yet. I used a program called "Device Driver Installation Wizard" to load mine. You need to do it with Norton's firewall and virus protection turned off. Then with the wizard program loaded you can load the driver package. If you are using Windows 8 use the driver called dpinst-amd64.exe and only that one. It will pop you into desktop where the wizard program will prompt you to got to 'next', and one of two drivers will be installed. that is all you need to do. then with your meter connected to your USB port click on the meter icon at the top left of the Radiant Lightspeed which should already be up and running in desktop and follow the icon out to meter connection and when you see the meter there click on it. Then you go to "graph" and click on it and start a new graph and name it. then go back to graph and click on to where the data is coming from, and that is "meter". Then you can start your data logging and it will prompt you to save it top a location. Etc. Good luck, Paul
Thanks for the quick help guys, i really appreciate it Im going to give it a shot this weekend when i have more spare time. this meter already helped me out a bunch.
i bought a 520nm 501b from tmack he measured 202mw and when i got it i put in the battery backwards and turned it on for maybe 3/4 of a second. but it still worked and was so bright when i put the battery in right. so i put it on my meter tonight and im getting only 110mw so the battery reversal must have hurt something.
