CHAPTER 9 SD CARD LOGGER
This section outlines how to setup, use and retrieve information from the SD
card on the Ultra 4.
About the Micro SD card logger
The Ultra 4 comes supplied with a micro-SD card capable of storing a vast
amount of logged data onto it at regular intervals which can be set in
program mode (Data Logs menu). The Ultra 4 detects the card when it is
inserted and prepares it for use. An SD card symbol appears alongside the
time at the bottom-right of the display, indicating the presence of the card.
Before removing the micro-SD card, the [.] button on the keypad should be
pressed – the LCD will briefly display a message ‘Safe to remove SD Card’
and the SD card symbol will flash about once per second. NOTE: If the SD
card is not removed when the SD indicator is flashing, the card will be
remounted after 5 minutes.
Types of Files
There are currently 5 file types that may be found on the SD card, a
description of these types is listed as follows:
Trend logs. These are stored in folders with the name format LyymmddX,
where L indicates that it is a data log-file, yymmdd are 2-digit year, month
and day, and X is a letter from A to Z that is added in case more than one
folder is created on the same date. For example, L190503A would be the
first trend file folder created on 5
th
May 2019.
The files within the folder have filenames of the format LhhmmssX.CSV,
where hhmmss represents hours (24hr), minutes and seconds. The file
extension .CSV indicates a comma-separated value file that can be opened
in a text editor or in spreadsheet applications. The data within the files
varies according to the configuration in the Data Logs menu, but each
record has a time & date stamp. A new trend log folder will be created each
day. Once a trend file reaches 1MB in size, a new file will be created within
the daily folder.
