[STANDBY (F2)]

This button makes the MEXA-584L instrument enter standby mode.

This button is available only when the MEXA-584L instrument is in measurement mode.

[LOGGING (F3)]

This button starts logging, or saving sequential measurement data as a CSV file.

1.Click the [LOGGING (F3)] button, and the LOGGING dialog box is displayed.

Fig. 2 LOGGING

2.Specify “Save in” and “file name” and click the [Open (O)] button. Logging starts, and the basic screen returns to LOGGING ON display.

Sequential measurement data (lapsed time, value for measured component) are saved.

To cancel logging start and return to the basic screen, click the [Cancel] button on the LOGGING dialog box.

3.When the LOGGING display is ON, Click the [LOGGING (F3)] button again, and logging terminates.

The following logging information is added to the header of the saved file.MEXA-584L Sampling Data, DATE, 2007/9/18, 12:34:56RATE:, 1, sec TIME:,1, min

Basic screen

[SET LOGGING PARAMETER (F4)]

This button allows to set logging conditions (sampling interval and sampling time).

The logging conditions can be set only when LOGGING is OFF.

1.Click the [SET LOGGING PARAMETER (F4)] button,

and the LOGGING PARAMETER SETTING dialog box is displayed.

Fig. 3 LOGGING PARAMETER SETTING

Note

Set a larger value for Sampling time than the value of Sampling rate.

Example:

The available Sampling time range for 61 s Sampling rate: 2 min to 10000 min

The available Sampling time range for 1800 s Sampling rate: 31 min to 10000 min

2.Set logging conditions and click the [OK (F4)] button. The logging conditions are

changed and the basic screen returns.

To cancel the logging condition change and return to the basic screen, click the

[CANCEL (F5)] button.

①Sampling rate

Set the data sampling frequency by the second (1 s to 1800 s).

One sampling will be executed every set time.

②Sampling time check box

Checking the box enables the upper limit for the sampling time that has

been set.

In this case, logging automatically ends at the set time.

Unchecking the box makes the set sampling time invalid.

If there is insufficient space available at the save destination, the data

will not be saved correctly, which will prevent the data from being

loaded. Make sure there is sufficient space available at the save

destination.

③Sampling time Set the upper limit of sampling time by the minute (1 min to 10000 min).
