1. Function
The Data Logger is a data collector for Stack TMS (Tele-Metering System). It is
important device as it is used for collecting data, and analyzing, storing them for
transmission to the connected server.
The Data Logger is able to execute the designated performance such as correction of
various measuring instruments from a host computer (Ministry of Environment’ s
server) by remote control when needed. The functions are as follows.
(1) Input/Output Function
ANALOG INPUT
