How can I set the recorded data type to "Display" and the recording interval to "2 sec" with SMARTDAC+ GX/GP series?

The display data settings are found in: MENU key > Browse tab > Setting > Setting menu > Recording Settings > Basic settings. From there, perform the following steps.

1. Tap File type > Display.
2. Tap Save.

The recording interval settings are found in: MENU key > Browse tab > Setting > Setting menu > Display settings > Trend interval. From there, perform the following steps.

1. Tap interval [/div] > 1 min (2s)
2. Tap Save.

For details, see “Advanced Operation (Various settings and operation)” in the first step guide (IM 04L51B01-02EN), and section 1.9, "Setting Recording Conditions (Recording mode, recording interval, saving interval" in the user's manual (IM 04L51B01-01EN).
