Networking features
The GL series carries two SD memory card slots for storage device. The SDHC type SD memory card is supported up to 32 GB. 4 GB SD memory card comes as a standard accessory installed in the first slot.
Accommodates a wide variety of measurements
Multifunction analog input ports: Contains a highly isolated input mechanism which ensures that signals are not corrupted by noise from other channels. This data loggers inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse signals.
Four channels if logic/pulse inputs: Supports four-channel logic or pulse signal inputs. Pulse mode allows cumulative, instant, or rotational values for industrial measurements capability with speed and flow.
Applications
Supports GL840, GL240, GL100
Up to 10 units of GL840, GL240 and GL100 can be connected to one PC simultaneously. Up to 1000 channels are supported.
Various measurement screen
Display data in Y-T waveform, digital monitoring, statistical calculation result. The direct-Excel function enables captured data to be written directly to an Excel file.
File operation
Data capture in multiple files can be merged into a single file. Using the combine function, data can be imported as a new channel overlaying on top of each other. The bind function connects the data in a time axis. When using the relay capture mode, the bind feature will append multiple files together into one large, continuous file.
Useful functions
Scheduling function: Create a schedule for your monitoring to start and stop at selected time, and set an automatic measurement schedule.
Group function: Multiple units can be managed, such as controlling start or stop simultaneously. Data captured by each unit is saved in a single file.
Data format conversion
Converts the GBD (Graphtec Binary Data) format to CSV format. The file size is reduced using the compression function saving a value at particular time point of a specified interval. Or, it will save the average, maximum, or minimum values from the specified time intervals as the highlighted values.
For PC
For smart device (GL-connect)
Apps for the smart devices are available on the Android OS and iOS platforms. Download them free from the individual stores.
Monitoring captured data: Real time captured data can be displayed as digital values in real time on the smart devices apps. The saved data on this data loggers main body can also be displayed in waveform display format (Captured data will not be saved on the smart device).
Set and control simple functions: Dedicated control features allow remote start and stop, setting the sampling interval, and setting the alarm conditions.
Control the settings remotely: Web server functions for this data logger allows remote control and monitoring using this application.
