CHAPTER 1 General Description
1.1 Overview
The GL220 (with color monitor and internal memory) are compact, lightweight data loggers.
GL220 are equipped with an Internal memory to enable the direct capture of a large volume of data to
USB memory. Furthermore, the data loggers can be connected to a PC via USB to enable on-line settings,
measurement, and data capture.
1.2 Features
Input
●Adoption of an M3 screw type terminal facilitates wiring.
●The GL220 enables settings to be made using dedicated keys and interactive menus, using just one hand.
Display
●With the GL220’s high-resolution 4.3-inch wide TFT color liquid crystal display, you can confirm the
waveforms of measured data and each channel’s settings at a glance.
Data Capture
●A large volume of measured data can be saved to a USB memory.
●The high-capacity internal memory enables measurement for a long term without the use of USB memory.
●The USB memory device can be removed and replaced without terminating data capture operations. This
allows any part of the data to be extracted during long capture operations.
●Internal memory used for the built-in memory maintains captured data even after the power is turned off.
●The Internal memory can be used with disk images thus multiple data items can be maintained.
●For voltage and humidity measurements, data can be captured up to a sampling speed of 10 ms/1ch
by setting fewer channels for measurement (sampling speed is 100 ms and above for temperature
measurements).
●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.)
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 GL220 units from a single computer to easily
perform multi-channel measurements.
●The USB drive mode function enables the GL220’s internal memory to be recognized as an external drive
by your PC. (Connect the GL220 to your PC and turn on the power supply to the GL220 while holding
down the [START] key.)
●Captured data can be read from the application software to files and displayed for processing.
●Data can be transferred off-line to a computer using USB memory.
