The last rig I did used hardware designed by us (using PIC Micro) to measure the coil resistance. However, the revised specification from the customer called for a 0.5% accuracy measurement of resistance over a range of 6 Ohms to 3000 Ohms, which proved to be a tall order. For a repeat order I am considering using a separate bench Digital Multimeter interfaced to the VEE program via RS232. Anyone know of a DMM which will meet the Spec. preferably for around 500.</FONT></DIV><DIV><FONT face=Arial size=2></FONT> </DIV><DIV><FONT face=Arial size=2>As usual, it really annoys me that I can easily find reasonably priced units shipped with LabView demos/examples but non for VEE (other than 1000 Agilent unit). If the Agilent unit proves to be the best option, then 'so be it' - I will have to recommend it.</FONT></DIV><DIV><FONT face=Arial size=2></FONT> </DIV><DIV><FONT face=Arial size=2>Regards</FONT></DIV><DIV><FONT face=Arial size=2></FONT> </DIV><DIV><FONT face=Arial size=2>Ashley.</FONT></DIV><DIV><FONT face=Arial size=2></FONT> </DIV>---<BR>You are currently subscribed to vrf as:<BR>To subscribe send a blank email to "".<BR>To unsubscribe send a blank email to "".<BR>To send messages to this mailing list,  email "".  <BR>If you need help with the mailing list send a message to "".</BODY></HTML>
