CHAPTER 1 General Description

1.1 Overview

The GL840 is a compact, lightweight, multi-CH, and multi-purpose data logger with a 7-inch color display.

20CH measurements are available with the standard terminal or Withstand high-voltage high-precision terminal, and 200CH measurements are available with the extension terminal base. In addition, when connecting various modules, the voltage, temperature and humidity as well as the acceleration, AC current, CO2, and illuminance / ultraviolet etc. can be measured.

The GL840 is compatible with the SD memory card. The high-capacity measurement data can be saved in the SD memory card that has various storage capacities.

For the PC interface, as USB and Ethernet is included as standard, system conguration according to use is possible. As the Ethernet function is equipped with both WEB server and FTP server functions, remote

supervision and data transfer are also possible. In addition, when the wireless LAN and Petit LOGGER GL100-WL are combined by installing the wireless unit, the multipurpose remote measurement is also possible.

1.2 Features

Input

Adoption of a pluggable M3 screw type input terminal facilitates wiring.

•

20CH measurements are supported by the standard terminal or Withstand high-voltage high-precision

•

terminal, and 200CH measurements are supported by the extension terminal base.

When using the Graphtec’s GS series and terminal / adapter, the acceleration, AC current, CO2, and

•

illuminance / ultraviolet measurements are also possible.

Because that standard terminal and Withstand high-voltage high-precision terminal have a whole CH

•

isolated, the different standard signals can be measured at the same time. In addition, when using the Withstand high-voltage high-precision terminal, the measure environmental conditions of high withstand voltage can be applied.

Display & Operation

With the GL840’s high-resolution 7-inch TFT color liquid crystal display, you can conrm the waveforms of

•

measured data and each channel’s settings at a glance.

Easy operation is achieved through a straightforward menu structure and key allocation which resembles

•

mobile phones.

Data Capture

Data is directly saved to the large SD memory card (Standard accessory: 4GByte).

•

There two mounting slots for the SD memory card, and long-term measurement can be performed while

•

backing up the data.

* When the optional wireless LAN unit is installed, the SD memory card cannot be inserted into the SD

CARD2 slot.

Because disk image can be used for the SD memory card , multiple data can be saved.

•

The new ring memory capture function maintains latest data even after capturing for a long term. (You

•

need to set how long you want to keep data.)

For voltage, temperature and humidity measurements, data can be captured at sampling rates of up to

•

10 msec per channel by using fewer measuring channels. (Temperature measurement can be done at sampling rates of 100 msec and higher.)

The GL840 is equipped with the relay recording function, and 2GByte or more data can be saved by

•

switching the to the other le without data missing. (When the capacity of one le reaches 2GByte, the le

is switched.)

1-2

CHAPTER 1 General Description

Data Control & Processing

The application software provided lets you set conditions and monitor data on a PC.

•

The USB drive mode function enables the SD memory card to be recognized as an external drive by the

•

PC. (Connect the GL840 to the PC and turn on the GL840 power while holding down the [START] key.)

The WEB server function enables control and monitoring from a remote location without using dedicated

•

software

The FTP client function enables backup of measurement data to the FTP server.

•

The NTP client function enables synchronization of the time with the NTP server.

•

When optional wireless LAN unit is installed, the data capture can be performed remotely by controlling

•

the G L10 0 -WL .

1.3 Operating Environment

This section explains the operating environment for the GL840.

CHAPTER 1 General Description

1.4 Notes on Temperature Measurement

Please observe the following precautions when performing temperature measurement.

Do not block the air vents. Always provide a space of at least 30 cm on all sides of the GL840.

•

For stabilized temperature measurement, allow the GL840 to warm up for at least 30 minutes after turning

•

it on.

Exposure of the input terminals to direct drafts, direct sunlight, or abrupt changes in temperature may

•

impair the equilibrium of the input parts and result in measurement errors. To measure temperature in such an environment, take appropriate countermeasures such as changing the installation site of the GL840.

To conduct measurement in noisy environments, connect the GL840’s GND terminal to ground (Refer to

•

“2.15 Noise Countermeasures”.).

If measured values uctuate due to noise, set to a slower sampling speed (Refer to “(2) DATA setting” in “3.4

•

Setting Menus”.).

1.5 Notes on Using the Monitor

The monitor is an LCD display unit, and so the display will vary depending on the operating environment.

If the screen saver function is used, it will operate and clear the screen if no operations are performed

during the preset time. If the screen saver operates, press any key to restore the display.

Condensation may form on the LCD screen if the GL840 is moved from a cold to a warm location. If this

•

occurs, wait until the LCD screen warms up to room temperature.

The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue, and

•

green dots may not disappear. Likewise, streaks may appear when viewed from certain angles. These phenomena are due to the LCD screen construction, and are not signs of a fault.

1.6 Changing the Display Language

You can choose the language displayed on the screen. The default display language is set to English when the GL840 is shipped overseas. To change the display language, see the instructions in "OTHER:Language".
