Wireless LAN & High-Performance Multi-Channel Data Logger GL260
Key Features
New service G-REMOTE
3 new functions (Alarm history, Improved Inter-CH calculation, Memory loop function)
The usability has been greatly improved.
Supports all channel isolated and multi-function input.
By narrowing down the number of channels, data are captured at sampling interval of up to 10ms is possible.
WLAN unit (optional) enables wireless measurement with a PC and remote monitoring.
Compact, standalone data logger with alarm history, memory loop, CH to CH calculation functions
Software provided for date logger settings, data recording, storage, playback; Intuitive UI design
Measurements - Voltage (20mV-100V); Thermocouple (K,J,E,T,R,S,B,N,C); Humidity (w/optional B-530)
4.3in TFT color LCD with improved visibility (increased chromaticity, font change, simplified menu)
Simplified waveform setting, web server function, Help QR code function
10 analog input channels; All channels isolated, balanced input; Scan channels for sampling
External input with optional cable – trigger of sampling (1 channel); Logic/Pulse (4 channels)
By narrowing down the number of channels, max sampling interval up to 10ms
8GB internal memory for reliable long-term measurement capture; Expandable with SD

The Graphtec GL260 is the functional replacement for the GL240 (same form factor) with enhanced capabilities. The internal memory has been increased to 8GB and is expandable via an SD card. A new battery is required for use in the GL260 (B-573).
The Graphtec GL260 display features increased chromaticity, changed font with added margins to improve visibility, and the menu tree has been simplified and made more intuitive. The operability improvements include a simplified waveform setting (SPAN /POSI/TRACE able to be configured in less steps), a web server function (faster update speeds/new setup screen) and a HELP-QR function (providing details on the related web page).
One of the new functions included with GL260 is an alarm history that shows the date/time history of alarm occurrence/cancellation. This is useful for wanting a record of condition or to check historical data during recording. The alarm history data is saved in .GAH format and can be opened as a text file.

Memory loop function
Ring capture function
The most recent data is saved when the memory is configured in ring memory mode.
Number of capturing data is 1000 to 2000000 points.
The capacity of one file and the number of data points are set, and when either is full, the old data is deleted and capturing continues.
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.
Set the capacity or capturing time of one file, and create a new file when either of them is reached.
Capturing will stop when the memory capacity is full.
Enables capturing without missing data
In addition to the existing relay capture function, the oldest file is automatically deleted before memory capacity runs out.
Hot-swapping the SD memory card
SD card can be replaced during data capturing when the sampling interval is 100ms or slower.

Back up recording data
The data file can be created periodically for purpose of backing up data while recording it, and the file is automatically transferred to another storage device on the unit or FTP server on the network.
Backup interval: 1, 2, 6, 12, 24 hour(s)
Backup file destination: SD memory card or FTP server
Data file format: GBD (binary) or CSV (text)
Available sampling speed is the 100 ms or slower when using the CSV format.
The storage device specified as the recording destination of the measurement data can not be set as the transfer destination of the backup file.
Data file verification
It is a function to check the integrity of the data file when replaying the data file. It compares check-sum generated from the data file and recorded check-sum. When two check-sums do not match, the data file may be corrupted or has been changed by someone. The check-sum code is recorded into the file when data file is created by the GL unit.
Check-sum code is added to normal data recording file and also file created for backup, ring or relay recording. Adding check-sum is available for data files created in GBD format.
