10.3.2 Web Server
The ND30 meter provides its own web server which enables remote
monitoring of the measuring values and reading a status of the meter. A web
page allows in particular to:
• obtain information about the device (serial number, code execution,
software version, bootloader version, version (standard or special),
• preview current measuring values, read a device status,
• select the web page language
Access to the server can be achieved by entering the IP address of the
meter in the web browser, for example: http://192.168.1.030 (where
192.168.1.030 is set address of the meter). The default web server port is
