Using the Hold Functions
Using the Hold Functions
The "hold functions" hold data for specific points during the measurement period, such as the
minimum and maximum values, and output those values after measurement ends.
■
Flow of Operation
Selecting the Hold Condition for Measured Values
The time period from the start to the end of hold measurements is called the "sampling
period."
The value to be held during that sampling period is selected here.
After sampling is started, the CLAMP value is output until the first sampling period ends.
What is the "CLAMP value?" p.77
Any of the seven settings shown in the following table can be selected as the hold
condition.

The maximum value during the sampling period is held. The output changes at
the end of the sampling period and is held until the end of the next sampling
period.
B-H (Bottom hold)
The minimum value during the sampling period is held. The output changes at
the end of the sampling period and is held until the end of the next sampling
