CHAPTER 1 General Description

1.1 Overview

The GL240 with color monitor is a compact, lightweight data logger.
The GL240 can save the high-capacity measurement data directly in the internal memory or SD memory
card.
In addition, the setting, measuring and data capturing can be performed in online by connecting to the
computer with the USB cable.

1.2 Features

Input
•
Adoption of an M3 screw type terminal facilitates wiring.
•
The GL240 enables settings to be made using dedicated keys and interactive menus, using just one
hand.
Display
•
With the GL240's high-resolution 4.3-inch TFT color liquid crystal display, you can confirm 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
•
The high-capacity measurement data can be saved directly in the internal memory or SD memory card.
•
Because the SD memory card is used as an external memory, you can measure a long period of time with
peace of mind while data backup.
* 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 internal memory, 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 ms per channel by using fewer measuring channels. (Temperature measurement can be done at
sampling rates of 100 ms and higher.)
•
The GL240 is equipped with the relay recording function, and 2GByte or more data can be saved by
switching the to the other file without data missing. (When the capacity of one file reaches 2GByte, the file
is switched.)
Data Control & Processing
•
The application software provided lets you set conditions and monitor data on on a computer using the
USB interface.
•
The application software allows you to control multiple GL240 units from a single computer to easily
perform multi-channel measurements.
•
The USB drive mode function enables the internal memory and SD memory card to be recognized as an
external drive by the PC.
(Connect the GL240 to the PC and turn on the GL240 power while holding down the [START] key.)
•
Captured data can be read from the application software to files and displayed for processing.
•
When optional wireless LAN unit is installed, the data capture can be performed remotely by controlling
the GL100-WL.
