Introduction
The HOLD menu allows for users to input a signal and then ‘hold’ the display on a desired value. A common use for this function would be to capture the peak (highest) input value. To do this you would select the peak function from the HOLD menu. The HOLD functions along with their definitions are listed below.

Some of the functions require additional information in order to accurately capture the desired value. Below lists the Hold Functions as well as the extra information needed for a specific function.

HOLD Function Definitions:
Sample Hold: The value on the display is held when hold signal is imputed.

Peak Hold: The maximum (peak) value in the positive direction is held. Some types of Peak Holds will require a time period setting (see 'Setting the Hold Detection Time').

Valley Hold: The maximum (valley) in the negative direction is held. Some types of Valley Holds will require a time period setting (see 'Setting the Hold Detection Time').

Peak-to-Peak Hold: The maximum difference from the triggered point is held. This triggered point is controlled by the T/H input. Some types of Peak Holds will require a time period setting (see 'Setting the Hold Detection Time').

Relative Minimum Hold: The relative minimum value from the triggered point is held. Remember to set the "minimum count" and valley detection level" when setting this function (see 'Setting Relative Maximums and Minimums')

Relative Maximum Hold: The relative maximum value from the triggered point is held. Remember to set the "minimum count" and valley detection level" when setting this function (see 'Setting Relative Maximums and Minimums')

Inflection Point Hold: The inflection point is the point at which a path changes its concavity. The display can hold the inflection point, however additional information must be entered (see 'Setting the Inflection Point')
