DDSJ 308A Conductivity Meter User Manual
The manual explains how to power on the DDSJ‑308A conductivity meter by plugging in the power cord, pressing the ON/OFF button and allowing a pre‑heat of at least 30 minutes. It details mode selection (Salinity, TDS, Conductivity) and the default Conductivity mode, as well as the required electrode constants and temperature compensation settings.
Procedures for measuring conductivity, shutting down the instrument, and routine maintenance are provided. Users are instructed on electrode handling, cleaning, and precautions such as avoiding corrosion and ensuring the electrode is fully immersed. The document also describes how to respond to an “overflow” indication by changing to an electrode with a larger constant. This manual is written in Chinese.
