Our SR560 was last sent in for a factory calibration and new battery in August 2026. Tips When changing the cables connected to A and/or B input, set the coupling to ground. This will protect the amplifier from unintentional voltages while you are making changes to the cabling. text/html 2026-09-03T00:15:04+00:00 ethanminot (ethanminot@undisclosed.example.com) https://minotwiki.physics.oregonstate.edu/doku.php?id=probe_station&rev=1788394504&do=diff Probe Station Voltage and current amplifiers We are typically measuring small currents and or small voltages.
