Extech EC600 Digital Conductivity/pH Meter User Manual
This user manual provides step‑by‑step instructions for using the EC600 handheld meter, including how to power the device, connect the electrodes, and select measurement modes for pH, mV, conductivity, TDS, salinity and resistance. It also describes the instrument’s back‑light, storage functions and safety features such as IP57 protection.
Detailed sections cover pH calibration procedures (three‑point, two‑point and single‑point), programming of parameters (temperature compensation, back‑light time, auto‑off), and maintenance tips for the electrodes and probe. Technical specifications, data storage capacity, battery information and certification details are listed at the end of the document. This manual is written in Chinese.
