This document provides information about the warranty terms and instructions for using Hanna Instruments, including the warranty period, coverage, and contact information.
This document serves as the instruction manual for the Hanna Instruments HI 86301, HI 86302, HI 86303, and HI 86304 portable meters designed for measuring Total Dissolved Solids (TDS) and Electrical Conductivity (EC). The meters feature automatic temperature compensation and a Battery Error Prevention System (BEPS) to ensure reliable readings. They are designed for simplicity of use with manual one-point calibration via a trimmer in the battery compartment.
The manual provides detailed instructions on preliminary examination, accessories included with each model, probe maintenance, battery replacement, and the procedures for taking measurements and calibrating the device. It also includes a warranty statement guaranteeing the instruments for two years against defects in workmanship and materials.

It is recommended to clean the probe at least once a month by immersing the tip in cleaning solution for half an hour.
The meters will display an additional blinking decimal point when the battery becomes weak, and the BEPS system may automatically turn the meter off.
Do not use the instrument when voltage at the measurement surface exceeds 24 Vac or 60 Vdc to avoid electrical shock.
