Up to 200 isolated
channels with multifunction input
The GL820 is fitted with 20 channels as
standard but can be expanded from 20 to 200 channels
with the optional B-537 and B-538 expansion
modules.

A
total of 500 channels can be monitored via the
GL820 software and up to ten GL820 units can be
networked as a complete data logging system.
Built-in
2GB flash memory for reliable measurements
The 2GB flash memory used for the built-in
memory device ensures that data is retained even
if the power supply is interrupted. This means
momentary disruptions in the AC power supply
or accidentally switching off power will not
result in
data loss.
Two ports are provided on the GL820, one for the plug-in USB memory
device and one for connecting to a PC.
Direct
record to a USB memory device
Commercially available USB
memory devices may be used for direct capture
of data.
In
addition, the GL820 can be connect directly
to a PC via the USB cable which allows data
to be transferred or measurements to be stored
directly to the PC. |

* The sampling rate is limited by the number of channels in use. (10ms: 1ch, 50ms: 5ch, 100ms: 10ch)
The multifunction GL820 device
can record voltages, temperature, current*,
humidity, pulse and logic signals. *External
shunt resistor required.
Voltage: 20 mV to 50 V
Current: 4-20 mA process
signals or larger currents with external shunts or Current transducers.
Thermocouples: K, J, E, T, R, S, B, N, W, (WRe5-26)
RTDs: Pt100, JPt100, Pt1000
(IEC751)
Humidity: 0 to 100%
(The B-530 option is required)

TFT colour LCD
...
The bright, easy-to-read
14.5cm(5.7")
TFT colour LCD monitor (VGA: 640 x 480 dots) makes it even easier
to review
measurement parameter settings, measured
waveforms, and digital values.
All
the GL820's functions can be accessed
through the navigation cluster and
LCD screen. Single
touch buttons for such tasks as display
mode, setup and logging start/stop
negate the need
for complicated menu trees.
9 hours of continuous
battery operations
Optional battery packs are available
for use in areas where AC power is unavailable
or subject to interruption. The battery packs
enables 9 hours* of continuous measurement and
provides a remaining battery capacity display
function. * Varies with measurement conditions.
Free
Bundled PC software
The GL820 is bundled
with PC application software that enables data logging directly to a PC. In addition
to waveform monitoring, this software provides
other useful functions such as direct writing
of data to an Excel file and report creation.
The software also provides a Help display
function for enhanced usability.
Diverse measurement
screens
Various display screens
can be selected: Y-T, X-Y, Digital, Meter,
and Report.
Multi-channel
measurement
One GL820 data logger enables
measurement on up to 200 channels at the
device itself, and up to 500 channels when
PC measurement has been specified. In addition,
since the channels can be assigned to four
display groups, they can be arranged according
to the input type.
Convenient functions
A function that displays
the logic alarm status during measurement
and a password protection function are
built in. Other convenient functions are
the display of a CSV file batch conversion
screen after captured data has been replayed
and various data search functions.
Software Features
- Configuration and
channel setup via USB or Ethernet Real
time data storage to hard disk.
- Stored data import
from GL820.
- Email notification
of errors and alarms.
- Available measurement
modes: Y-T and X-Y.
- Separate screens are
available for each of the settings.
- Direct Excel
transfer can be enabled as a report
function.
Remote monitoring
via Ethernet; Web server/FTP functions
Your PC’s Firefox,
Opera or Internet Explorer applications
can be used for settings, control, data
monitoring and data acquisition.
The Web server function
enables the acquisition of setting control
data.
The FTP function enables
the acquisition of data stored to the GL820.
