When using long averaging times (greater than 300 seconds), all
timing parameters should be set to integer multiples of the boxcar
size (see the STA command under "Set Commands" in Chapter 6).
This minimizes data loss that may occur if autozero transitions
occur during the middle of a measurement boxcar.
