Graphtec America GL220 - Midi Logger
10 isolated channels, each with multifunction input
Its compact size contains an isolated input system which ensures that signals are not corrupted by inputs to other channels, thus eliminating wiring concerns. The GL220s multi-type inputs are suitable for voltage, temperature, humidity, pulse, and logic signals, enabling combined measurements of different phenomena like temperature/humidity and voltage.
*) The input signal needs to be not exceeding the specified voltage at any time.
The component in the amplifire of the unit may have the damage by over voltage.
Please check the details of over voltage in the specification sheet (Maximum input voltage or Withstand voltage seccion) or the caution label attached on the unit.
Maximum sampling rate of up to 10ms
Provides faster sampling rates for voltage measurements. Can achieve 10ms sampling interval when limiting the number of channels in use.
|Number of channels||1||2||5||10||10|
X: selection is available, N/A: selection is not available.
*2: For humidity measurements, the 0-1V range and scaling function are used to display results directly in Relative Humidity. Sampling rate limitations are same as those for voltage measurement.
Large easy-to-read 4.3-inch wide TFT color LCD
Utilises a bright clear 4.3-inch wide TFT color 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 color of the screen can be set to black or white.
Waveform display (Analog + Digital)
Dual display (Current + Past)
Waveform display (Analog only)
Built-in 2GB Flash Memory
Built-in 2GB Flash Memory for reliable long term measurement
The 2GB Flash Memory enables secure long term data measurement without using an external storage device. Data is retained even when power is turned off because flash memory is used.
Capturing time*4 (10 Analogue channels being used.)
|Built-in 2GB Flash memory||38 days||83 days||97 days||194 days||485 days||971 days||9,714 days|
|512MB USB memory stick*6||9 days||21 days||24 days||49 days||124 days||248 days||2,481 days|
*5: The sampling rate is limited by the number of channels in use. (10ms: 1ch, 50ms: 5ch)
*6: Standard USB memory devices without high-end functions such as fingerprint recognition are required.
Hot-swappable USB memory sticks
Also supports popular USB memory sticks for external storage. The GL220 saves measured data directly to USB memory sticks. USB memory sticks can be replaced during measurement without data loss.
Ring memory function
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.
Easy operation and device setup
Ergonomically 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 application software
Easy connection to PC
The GL220 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 GL220 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.
Various measurement screens
Select 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.
Substantial data replay screens
Three 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 screens
The number of configuration screens has been reduced to five. Parameters can be set easily while viewing measured waveforms.
Post-process your captured data with useful functions for arithmetic calculation, statistical calculation, search and file format conversion.
Can be used with 3 types of power source
Chose from AC supply, DC supply or the optional battery pack which enables 6 hours*7 of continuous measurement. The power source is automatically switched to the battery pack when the AC power supply is interupted. If the capacity of the battery pack goes low then measurement is automatically terminated and the captured data file is closed and protected.
*7: DC power drive cable and battery pack are optional extras. Measuring time by using the battery pack varies on the conditions.
Alarm output function
Alarm signals can be output when alarm conditions occur. Four alarm output ports are fitted.*8
*8: The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports.
Measured data can be compared with other channels in real-time. Four arithmetic functions can be selected. The calculation result is saved as measured data when the built-in memory or the USB memory stick is selected as the destination for the captured data.
