content: Hi,I'm sorry, but let me put my two cents - are you interested in some special kind of card ? (thermocouple, digital I/O, high voltage, low voltage precision, ...)I don't have one but thinking about smth like that:https://xdevs.com/review/kei7168/.Price and condition will seriously wary depending on the card purpose, and others may feel more confidence about whether they have what you need or not if you give more info.Thanks

content: I need explicitly the card "Keithley 2000-Scan" since i want it to use in my Keithley 2010 Multimeter. ->https://cdn.testequity.com/documents/pdf/keithley/2000-SCAN-Manual.pdfOther cards which fit in 7001/7002/705/706-Mainframes wont fit in the Keithley 2010.Needed card can be used, as long as the relay contacts arent at their end of life.

content: There are still two kind of cards: 2000SCAN and2001-TCSCAN. They are very different.If you going to hunt microvolts/resistance or thermocouple measurements, you may want to look for 2001-TCSCAN that have onboard temperature sensor.

content: Quote from: Echo88 on January 14, 2019, 12:40:58 pmI checked this a while back and it seems the relays are readily available at a decent price. They should be replaceable.

content: In addition to the 10-channel 2000-SCAN and the 9-channel 2000-TCSCAN (with virtual cold junction to support thermocouple measurements), there are at least two other types. The 2000-SCAN-20 is a 20-channel, 2-pole scanner. The 2001-SCAN is similar to 2000-SCAN but channels 5 and 10 utilize opto-isolated MOSFET relays that enable high speed scanning between those two channels.I have a scanner card in a 2001, but I don't use it and it's not connected to anything. I am 99% sure it is a 2001-SCAN but I'll need to physically verify that. I'd be willing to part with it for a reasonable price. The question is: ismyreasonable price close enough toyourreasonable price.

content: Pardon the newbie question, but what's the function of a scan card?I tried reading the manual but it assumes the reader already has some background knowledge, which I don't.

content: Quote from: aix on January 14, 2019, 10:51:11 pmIts basically just a card with some relays that allows you to switch many inputs to the multimeter. Its useful if you need to measure e.g. 10 different voltages(or currents, temperatures,etc) at roughly the same time.You can get cards that just switch voltage, you can get cards with temperature compensation(needed for thermocouples), cards for switching RF around, etc.

content: I periodically look around for one of these. Don't really need one often but like filling in the slots in instrumentsI've wondered if it's worth just building one. They seem to be no more than a bunch of latch/driver ICs and the relays. Maybe some links on the connector to identify it.
