Looking for PC to monitor dicharge cycle of battery pack

Post by Rstacy » Thu Feb 20, 2003 3:43 pm

My peak charger will discharge and then charge a battery pack for me. Is there an interface availble that will let my PC monitor the voltage and perhaps graph it showing voltage and time?<p>Ray

If you're looking for real cheap and dirty you can read the analog inputs of your game port with basic. Calibration will be up to you.
If you want to spend money there are dmm's with pc interfaces starting at around $100.
There are also analog input cards for a pc for around the same price.

A 12 bit A/D board plugs into parallel port. It can be found in kit-form for around $45. The software allows data points to be charted.<p>http://www.web-tronics.com/webtronics/12bitdatacki.html<p>[ February 20, 2003: Message edited by: dim bulb ]</p>
