10 SC Shunt Calibration
Note 1: The three channel blocks each share three signals [within their block], as follows:
For CH1, CH2, CH3, and CH4, the signal values of pins 6, 7, and 9 are shared.
For CH5, CH6, CH7, and CH8, the signal values of pins 6, 7, and 9 are shared.
For CH9, CH10, CH11, and CH12, the signal values of pins 6, 7, and 9 are shared.
Note 2: The 6224 only supports TEDS if the acquisition software being used supports TEDS.
Do not connect an RJ45 plug to an RJ50 jack. Using RJ45 plugs can
cause permanent damage to RJ50 pins 1 and 10, thus disabling shunt
calibration.
