g. Verify that the measured output (M1-M2) is within the warranted
specification listed, by computing %Error as follows:
For example, you may measure values of 0.990 V for M1 and -0.998 V for M2.
With an expected V
E
of 1.0 V, you compute the %Error as follows:
5. Record the results on the test record.
6. Disconnect the DMM cable from the amplifier and the probe from the 5T coil.
