This instruction manual describes the operation of the meter. The state-of-art meter that you have purchased is easy to operate and will guide you through the various functions by displaying easy to understand prompts. This instruction manual is designed to provide all the information necessary to guide you through the process of measuring Conductivity, Resistivity and Total Dissolved Solids with a series of prompts on the screen. You will find this symbol appearing in this manual; it indicates useful tips that ease your meter operation. The CyberScan CON 1500 provides microprocessor precision in a compact bench top design that is easy to use. This meter allows you: Measure Conductivity, Resistivity and Total Dissolved Solids (TDS). Select cell constants, temperature coefficients, normalised temperature, TDS factor and temperature units. Replatinise your conductivity probe It all adds up to rapid, completely automatic, intuitive operation. 1 Instruction Manual CyberScan CON 1500 2. 2.1. GETTING STARTED Connectors 1. Review the layout and arrangement of the rear connector panel. 2 Instruction Manual CyberScan CON 1500 2. Connect the electrode arm to the base plate. 3. Connect the power adapter's output power jack to the meter's rear panel DC input power socket and plug in the adapter to a power source. 3 Instruction Manual CyberScan CON 1500 3. 3.1. USING THE METER Conductivity Probes This meter allows you to use either the 2-cell or 4-cell conductivity probes. DO NOT connect both probes together. Remove the protective cover from the end of the probe. Prior to use, soak the probe in distilled or deionised water for 10 minutes. You may either:1. Connect the 2-cell probe by plugging its pin connectors into the dual pin sockets located at the rear panel of the meter. 2. Connect the 4-cell probe by plugging its DIN connector into the DIN socket at the rear panel of the meter. 3. Connect the ATC probe by plugging the 1/8" mini-phone jack into the ATC socket located at the rear panel of the meter. The Eutech Instruments 4-cell probe has a built-in temperature sensor and therefore a separate ATC probe is not required. 4 Instruction Manual CyberScan CON 1500 1. Rinse the conductivity probe sensing elements with distilled or deionised water between samples. 2. For long term storage, the probes can be stored dry or in distilled water. Note that the cell constant may change slightly due to storage or use, and it must be re-evaluated with the use of standard conductivity solution (standardisation) prior to use. 5 Instruction Manual CyberScan CON 1500 3.2. Display/ Keys Overview of the meter screen display and function key layout. Press std key to initiate standardisation. Or press std key at the `Standardize' mode allows you to exit and return to measurement mode without accepting the calibration. Press mode to select uS, kohm or TDS.
