Calculate the offset gain using the following expression and record this value in the
15
DC Gain Test section of the Performance Test Record.
For vertical sensitivities of less than 1 volt use the following equation:
DCGainError =
For vertical sensitivity = 1 V use the following equation:
DCGainError =
