Holding, Starting, and Stopping Integration
When the display is held, the integration operation continues, but the display and
transmission of the integration result are held. The relationship between the hold function
and the start and end operations is as follows:
• If you start integration while the display is held, the display and communication output
do not change. When you release the hold function (turned it off) or make a single
measurement by pressing SHIFT+HOLD (SINGLE), the integration result at that point
is displayed or transmitted.

• If you stop integration while the display is held, the displayed and transmitted values
do not change. When you release the hold function (turn it off) or make a single
measurement by pressing SHIFT+HOLD (SINGLE), the integration result at the point
when integration was stopped is displayed or transmitted.

Sample Rate, and Valid Frequency Ranges for Integration
The sample rate is approximately 100 kHz. The voltage/current signal frequencies that
are valid for integration are as follows:
