– When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.
– When there are meany number of active channels, the sampling time is fast, or the backup interval is long, it may take time to closing the data file after recording stops because the size of the data to be backed up becomes large.
– When saving file to FTP server using wireless LAN connection, backup may fail depending on the communication condition.
– Available sampling speed is the 100 ms or slower when using the CSV format.
– When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available.*9Size of the capture data will be limited to 1/3 of available memory.*10Display mode is switched every time the dedicated key is pressed.

Introduction Graphtec midi LOGGER GL240
The Graphtec midi LOGGER GL240 is a versatile data acquisition instrument designed for recording and analyzing various types of data in real-time. It’s a part of Graphtec’s line of data loggers and is commonly used in research, industrial, and scientific applications where precise data collection is essential. The GL240 is known for its reliability, user-friendly interface, and the ability to handle a wide range of input signals.
The midi LOGGER GL240 offers multiple input channels, allowing you to simultaneously record data from various sources. These sources can include voltage, temperature, humidity, pulse, and more, depending on the type of sensor or signal you’re using. The compact and portable design of the GL240 makes it easy to transport and set up for data collection in different environments. This portability is especially useful for fieldwork or when you need to move the logger between different locations.
The device features a built-in touchscreen display that provides an intuitive interface for configuring settings, monitoring data in real-time, and reviewing recorded data directly on the device. The midi LOGGER GL240 supports high data sampling rates, which allows it to capture rapid changes in signals with precision. This is particularly important for applications where fast changes need to be accurately recorded. The device comes with internal memory for data storage. Additionally, it typically supports external storage options such as SD cards or USB drives, which means you can store a large amount of data without worrying about running out of space.
Graphtec usually provides software that accompanies the GL240, allowing you to easily transfer recorded data to a computer for more in-depth analysis. This software often includes tools for graphing, analyzing, and exporting the data.
