A used Guildline 9975 DC Current Comparator Resistance Bridge arrived in a big box yesterday. After some repairs, the unit appears to work, but I have never used one of these bridges before.
Why do I say it appears to work? Here are two measurements comparing one Ohm resistors at 30 mA current: L&N 1 Ohm versus Resistor #2 0.9999372 Resistor #2 versus L&N 1 Ohm 1.0000630 The above measurements appear consistent (or I got lucky), but there are several controls/functions I do not understand how to set or use. Does anyone have a Guildline 9975 manual I can buy or borrow and copy? Who has experience with the 9975 and can give me some pointers? Thanks and Happy New Year everyone, Joe Hobart Flagstaff, Arizona _______________________________________________ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
