9.5 Performing Remote Operation Using the HTTP
Server
This section describes how to use the instrument’s HTTP server function to control it remotely using
a computer.
You can congure the instrument’s settings, acquire measurement data, and monitor the display
through a commonly used web browser, including Internet Explorer
®
.
To perform remote measurement using the HTTP server function, you must congure LAN settings
and use a LAN connection.
When accessing the HTTP server, the communication command setting header will be set to OFF.
You cannot perform the remote operation through the HTTP server during measurement using the
Logger Utility or programs, including those created with Visual Basic®.
Some browsers may be unable to connect to the HTTP server if the FTP/HTTP authentication
setting is enabled. In this case, either use a di󰀨erent browser or disable the FTP/HTTP
authentication setting.
After updating the instrument’s rmware, the remote operation function may open the page from the
previous version or otherwise fail to function properly. In this case, delete your browser’s cache and
connect again.
If you attempt to set the time during HTTP-server-communications, the communications may be
disrupted.
