How do you know that the Datron 4000 requires an option to output current and ohms? From looking at the limited specifications that are available online it appears that no additional options are called out and that all 4000/A units have DC V, I and ohms. This Datron multifunction calibrator shopping experience has been a very frustrating one thus far. I feel that no matter how much research I do, I get conflicting information and end up spending thousands on units that lack the capabilities I need. :( not fun...

You seem to have more money than patience. Simply Googling Datron 4000 option returned these on the first page: http://www.test-italy.com/Specifiche%20strumenti%5CDATRON%5CDATRON%204000-4000A%5CDatron%204000A.pdf 20: DCI and OHM functions http://www.custom-cal.com/%28S%28gyvxsc210paqkz45lswhc03f%29%29/ModelInfo.aspx?kn=8351&m=DATRON_4000&srv=Repair 20: DCI and ohm Functions Did you already checked if your 4708 has the R/I? If the led turns on when you press the resistance button, then you have the card installed. 2014-07-20 19:41 UTC+03.00, Chris <caall99@gmail.com>: > How do you know that the Datron 4000 requires an option to output current > and ohms?
