1 1. Introduction thank you for purchasing our pc 700 series benchtop meter. This microprocessor-based meter is economical and simple to use. The design incorporates a large lcd for clear viewing, yet offers a small footprint to conserve space. The pc 700 measures ph, mv (orp), conductivity, or tds ...
2. Getting started 2.1 keypad functions powers the meter on and off. Upon power on, the meter automatically begins in the mode that was last used. Calibration and memory values are retained even if meter is unplugged. Toggle between available measurement modes— ph/temp, mv/temp, conductivity/temp, o...
