The total amplitude correction value composed of linear/log scale offsets, bandwidth errors, and attenuator errors
can be output to a computer/controller with KS91. This error can then be corrected with software to yield a more
accurate amplitude measurement.
Correction values are stored in memory for a 30-day period in the event of power-line failure.
