2. Apply calibration voltage from the precision calibrator to the first channel of each card (see following
table), and verify with a digital multimeter. Requirements for both devices are specified in Required
Equipment.

Note: In the slot columns, the digit after the G is the channel number and the number immediately preceding
the X assigns the voltage value, e.g., G1,1X means "Calibrate Gain for channel 1, ±50 mV."
