Memory Mode

This chapter describes the

Memory mode

designed to record in real time the measurement data made on the channels

into the internal memory.

You can start and stop the data acquisition under various conditions. You can simultaneously save measurements on file.

7.1 Setup and start of the data acquisition

Setup of the data acquisition into internal memory. Press

to open the setup screen, see

Figure 7.1

Memory Mode Setup

1. Blocks: parting of the internal memory in blocks

−

1, 2, 4, 8, 16, 32, 64 or 128

−

Erase blocks: erasing of all blocks: the current block is #1

2. Acquisition period: sampling rate of the channels

−

internally paced from 1µs to 10min

−

externally paced by the logic channel 16

3. Start: start condition of the data acquisition

−

Manual: with the

key

−

Trigger: with a channel, with a combination of analog and logic channels

−

(see chapter 5)

−

Stand-by: after a delay or at a precise date and time

−

Automatic: imimageste; automatic stop when the block is full
