Huge 2GB Flash Memory, modular system allows expansion up to 200 channels

Modular system allows expansion up to 200 channels

The standard configuration has 20 analogue input channels. It can be expanded up to 200 channels by adding optional 20 channelextension terminal kits.

Configuration for additional channels

Number of channels	20 ch	40 ch	100 ch	200 ch
GL820 Unit	1 set	1 set	1 set	1 set
Extension terminal base kit (B-537)	N/A	1 set	1 set	1 set
20ch extension terminal set (B-538)	N/A	1 set	4 sets	9 sets

All channels are isolated, each with multifunction input

Isolated channels, each with multifunction input
It contains an isolated input system which ensures that signals are not corrupted by inputs to other channels, thus eliminating wiring concerns. The GL820s multi-type inputs are suitable for voltage, temperature, humidity, pulse, and logic signals, enabling combined measurements of different phenomena like temperature/humidity and voltage.

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.

Sampling interval		10ms	20ms	50ms	100ms	200ms	500ms	1s	2s
Channels		1	2	5	10	20	50	100	200
Measurement^*2	Voltage	X	X	X	X	X	X	X	X
Measurement^*2	Temp.	N/A	N/A	N/A	X	X	X	X	X
X: selection is available, N/A: selection is not available
^*2: For humidity measurements, the 0-1 V range and scaling function are used to display results directly in Relative Humidity. Sampling rate limitations are same as those for voltage measurement.

External sampling function

Captured data can be synchronized with external timing signals when the external sampling rate function is used.^*3

^*3: The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports.

Huge 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 (20 Analogue channels being used.)

Sampling interval	10ms^*5	50ms^*5	100ms^*5	200ms	500ms	1s	2s
Built-in 2GB Flash Memory	29	72	89	101	253	506	5,068
512MB USB memory stick^*6	7	18	22	25	64	129	1,294
^*4: The above figures are approximate.
^*5: The sampling rate is limited by the number of channels in use. (10ms: 1ch, 50ms: 5ch, 100ms: 10ch)
^*6: Standard USB memory devices without high-end functions such as fingerprint recognition are required.

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.

Hot-swappable USB memory sticks

Also supports popular USB memory sticks for external storage. The GL820 saves measured data directly to USB memory sticks. USB memory sticks can be replaced during measurement without data loss.

Large easy-to-read 5.7-inch wide TFT color LCD

Utilises a bright clear 5.7-inch wide TFT color LCD monitor (VGA: 640 x 480 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.

PC-friendly, supports USB memory stick, has USB and LAN ports

Supports USB memory devices

Captured data can be saved directly to USB memory sticks when these are chosen for external storage.

Easy connection to PC via USB or Ethernet

The GL820 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 GL820 can emulate an external USB drive for quick data transfer.

The WEB & FTP server function, FTP client-server function and NTP client function are supported when the GL820 is connected to the LAN via the Ethernet port.

Easy application software

Easy connection to PC

The GL820 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 GL820 can emulate an external USB drive for quick data transfer.

Up to 10 units or 500 channels can be connected to 1 PC through LAN or USB. 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.

Informative data replay screens

Three screens are available to view measurements in replay mode. The Y-T (waveform) display, the digital display and the X-Y graph can be selected to show your specified data. The maximum, minimum, average and peak-to-peak values between cursors are shown when using 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.

Useful functions

Post-process your captured data with useful functions for arithmetic calculation, statistical calculation, search and file format conversion.

The configuration of CSV file can be specified.

Other features

Alarm output function
Alarm signals can be output when alarm conditions occur. Four alarm output ports are fitted.^*7
^*7: The Logic/alarm cable, (B-513 option), is needed to connect the alarm output ports.

Alarm warnings can be sent via E-mail when computer is connected to LAN.

Can be used with 3 types of power source

Chose from AC supply, DC supply or the optional battery pack which enables 6 hours^*8 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.

^*8: DC power drive cable and battery pack are optional extras. Measuring time by using the battery pack varies on the conditions.
