The GL240 is the next generation midi logger following on from the success of the GL220 model. With 10 fully isolated multi-function inputs and 4G of SD Card flash memory and now optional WiFi communications, this logger has an exceptional cost to performance ratio. With its large format colour display, you can easily set up and capture data with the ability to monitor waveforms and digital values during measurements. Its instant replay function makes it easy to review data that has been captured to internal memory or removable USB memory stick storage. Standard PC interface makes GL240 accessible through USB.
GL240 is a third-generation data logger product with exceptional price/performance. It’s a 10 analogue channel device augmented by four discrete inputs and outputs. Its discrete inputs can be configured as a group to be either logic inputs or pulse inputs. When configured for pulse, each of the four channels can be configured to measure frequency or to count. The four discrete outputs are alarms that can be triggered by a variety of easily-defined analog and pulse/discrete input channel conditions.
The 10 GL240 analogue input channels may each be configured to measure a direct connected voltage in the range of 20 mV to 100 V full scale across 12 ranges, or for a direct-connected thermocouple of any type to measure temperature. Each of the GL240’s analogue input channels is electrically isolated from other channels and from power ground allowing off-ground measurements using shunts, as well as powered or grounded thermocouples.
The most powerful GL240 feature is its triggering flexibility. Data recording can be independently started or stopped as a function of analog and pulse/discrete signal level (single or windowed), alarm, date and time, and day-of-the-week. Triggers can also be configured to operate only once, or to automatically repeat. The ability to of the GL240 to adapt to virtually any desired trigger condition allows the instrument to operate unattended for long periods of time with complete autonomy.
The GL240 operates either connected to a PC or entirely stand-alone. Connection to a PC may be over a standard USB or optional wireless connection. Either connection approach may take advantage of supplied PC-side software to configure, acquire, display, and record digitized information for storage directly to the PC’s HDD. Acquired data may be retrieved for review and analysis after recording, including the ability to export to Microsoft Excel.
Using the GL240’s wireless option enables the instrument’s networking features, allowing it to be remotely configured and managed using the standard Web browser of any computer or smart phone. Automatic backup of data acquired to a user-accessible SD memory card isalso supported via its FTP facility.
Finally, the measurement reach of a wireless-enabled GL240 is further extended by use of the GL100 accessory. The GL100 wirelessly enables measurements of temperature/humidity, acceleration, CO2, illuminance, ac current, and more.
Provides faster sampling rates for voltage measurements. Can achieve 10ms sampling interval when limiting the number of channels in use.
Large easy-to-read 4.3-inch wide TFT colour LCDUtilises a bright clear 4.3-inch wide TFT colour LCD monitor (WQVGA: 480 x 272 dots). Makes it easy to read data in waveform or digital form and to check your measurement parameter settings. The background colour of the screen can be set to black or white.
SD Flash Memory for reliable long term measurement
New GL240 series carries two SD memory card slots for storage device. The SDHC type SD memory card is supported up to 32GB. 4GB SD memory card comes as a standard accessory installed in the first slot. The captured data can be stored in GBD (Graphtec binary data) or CSV file format.
The most recent data is saved when internal memory or external memory is configured in ring memory mode. Captured data size in ring memory mode is limited to 1/3 of available memory.
Relay capture function
Data is continuously saved to multiple files up to 2GB without losing any data until capturing is stopped when the memory is configured in the relay mode.
Hot-swapping the SD memory card
SD card can be replaced during data capturing when the sampling interval is 100ms or slower.Easy operation and device setupErgonomically designed and easy to operate, just like a mobile device. The input/output terminals and keybord layout are arranged so that it can be operated in hands-on mode even when recording data. Parameters in the AMP settings menu can be easily changed whilst viewing the waveform.Easy connection to PCThe GL240 can be controlled by a PC if connected by USB cable, allowing transfer of data to a PC in real-time. If you need to move large data files to your PC then the GL240 can emulate an external USB drive for quick data transfer.
Up to 10 units can be connected to 1 PC. Measurements can be performed simultaneously or independently
Wireless measurement using wireless LAN (option)
Wireless LAN option enables the wireless communication with other device. Connects to the GL100-WL wireless unit remotely when the GL240 is set as an access point. When the GL240 is set as a station, a PC and smart devices will be able to access the WLAN unit directly.
Application software for PC
Various measurement screensSelect from 4 screens such as the Y-T (waveform + digital), Y-T (large waveform), digital view and report view to display measurements in real time. The direct-Excel function enables captured data to be written directly to an Excel file.Data replay screensThree screens such as the Y-T (waveform), digital and the X-Y graph for specified data are available to view measurements in replay mode. The maximum, minimum, average and peak-to-peak vales between cursors are indicated in the digital display screen.Simple configuration screensThe number of configuration screens has been reduced to five. Parameters can be set easily while viewing measured waveforms.Useful functionsPost-process your captured data with useful functions for arithmetic calculation, statistical calculation, search and file format conversion.
