Data Control & Processing
•
The application software provided lets you set conditions and monitor data on a PC.
•
The USB drive mode function enables the internal memory and SD CARD to be recognized as an external
drive by the PC.

[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 unit is installed, the data capture can be performed remotely by controlling the

1.3 Operating Environment

This section explains the operating environment for the GL840.

Ambient Operating Conditions

(1) Ambient temperature and humidity (the GL840 must be operated within the following ranges.)
• Temperature range: 0 to 45°C (0 to 40°C when a battery pack is mounted, 15 to 35°C when battery is
being charged)
• Humidity range: 5 to 85%R.H.
* When the screwless terminal (B-564SL) is connected to the GL840, it is necessary to use it in the
environment of the GL840.
