Avg/Hold Number
Specifies the number of N averages that will be used for the measurement. After the specified number
(average counts) have been averaged, the averaging mode (termination control) setting determines the
averaging action.

Avg Mode
Toggles the averaging mode between Exp (exponential) and Repeat. This selection only affects the
averaging result after the number of N averages is reached. The N is set using the Avg/Hold Number key.
Exponential
Each successive data acquisition after the average count is reached, is exponentially
weighted and then combined with the existing average.
Repeat
After reaching the average count, the averaging is reset and a new average is started.
