This document is a ST series pen type conductivity, TDS, salinity meter instruction manual, which introduces the use method, measurement method, attention matters and so on.
This manual covers the OHAUS ST Series of waterproof pen meters, which includes models for conductivity (ST10C), Total Dissolved Solids (ST10T), and salinity (ST10S). These devices are factory calibrated and designed for easy, accurate measurements in various environments.
The document provides instructions on initial usage, such as conditioning the electrode in pure water for 0.5 hours. It details the measurement process, including removing the protection cap, rinsing the electrode, and waiting for the reading to stabilize. Maintenance instructions specify cleaning the electrode before and after each measurement and replacing the four 1.5V AA batteries when the display fades.
