Trigger Functions to Control Data Capture Start/Stop Operations

1. Starting data capture
Trigger functions can be used to control the timing of the start of a data
capture operation, and the timing of the end of a data capture operation.
For example...
The trigger function performs operations such as the following:
• Start data capture when the voltage exceeds 1 V
• Stop data capture at 1:00 pm
• Perform control via external input
The example of the data capture start in the temperature setting conditions is
described below.
Here data capture is started in the condition as "Start data capture when the
CH1 temperature exceeds 20ºC".
(1) Press the [MENU] key and open the "TRIG" menu.
(2) Move the cursor to "Start Source" and select "Level".
(3) Press the [ENTER] key according to the "Level Settings". The "Trigger
Level Settings" screen is displayed. Move the cursor to the "Mode" for
the CH1, and then select "H".
