EcoScan CON 5 / TDS 5 1. INTRODUCTION 1.1 Introducing the EcoScan Series Thank you for purchasing Eutech Instruments’ EcoScan Conductivity and Total Dissolved Solids (TDS) meter series. These economy microprocessor-based handheld meters deliver up to ±1% full-scale accuracy. It has a large custom LCD (Liquid Crystal Display) for clear and easy reading. EcoScan CON 5 measures Conductivity (uS/mS) and Temperature (oC) while the EcoScan TDS 5 measures Total Dissolved Solids (TDS) and Temperature (oC).
EcoScan CON 5 / TDS 5 2. GETTING STARTED 2.1 Description of Keypad Functions The EcoScan CON 5/TDS 5 meter has 6 keys on its splash-proof keypad. These comprise ON/OFF, HOLD/ENTER, CAL, MODE, ∆ and ∇ keys. ON/OFF: Powers the meter on and turns it off. Meter directly enters measurement mode when you switch it on. MODE: Selects measurement mode for Conductivity/TDS or Temperature, CAL: Allows calibration mode for Conductivity/TDS and Temperature, or to abort calibration without confirming any set value.
EcoScan CON 5 / TDS 5 2. To insert meter into rubber boot, slide in from the top of meter before pushing the bottom edges of meter down to set it into position. Lift up the stand at the back of meter for bench top applications if necessary. 2.4 Inserting New Batteries The battery compartment is found at the back of instrument. To open the battery compartment, push in the direction of arrow and lift up the cover. Note the polarity of battery before inserting into position.
EcoScan CON 5 / TDS 5 2.5 Battery Replacement A “LO” annunciator in the LCD alerts you when battery power is running low. Replace with the same type as recommended by the manufacturer. LO 1420 uS Caution: Power off the meter when changing battery. 2.6 Connecting the Electrode and Temperature Sensor To connect electrode into meter, align the connector slots with the posts of meter’s socket and rotate connector clockwise until it locks. Do not force when connecting.
EcoScan CON 5 / TDS 5 2.7 Switching the Meter On 1. Press ON/OFF key to power up your meter. All LCD segments display momentarily as the meter performs a self-diagnostic test, per shown in section 2.2. The LCD switches into Conductivity or TDS measurement mode. 2. Press MODE key to choose your desired mode of measurement with its corresponding annunciator displays in the LCD. For temperature mode, the measured reading can be 25.
EcoScan CON 5 / TDS 5 2.8 Setting the Conductivity-to-TDS Conversion Factor (EcoScan TDS 5 Only) The EcoScan TDS5 is set to a default conversion factor of 0.67. This should give good results for most applications (including natural waters and other applications that calibrate to 442 standard solutions). You can adjust the factor for different salts, chemicals, or nutrient solutions using the following procedure. Note the meter allows adjustment of 0.50 to 0.85. 1. Turn meter on and press HOLD key.
EcoScan CON 5 / TDS 5 3. CALIBRATION 3.1 Conductivity Calibration (EcoScan CON5) The meter is capable of calibrating 1 point per range (3 points across entire measurement range). If a range is not calibrated, the meter automatically detects the closest range calibrated and uses the calibration information. Calibrate to all measurement ranges to ensure the highest accuracy throughout all measurement range. Note that EcoScan will not accept calibration values less than 40 µS/cm (20 ppm).
EcoScan CON 5 / TDS 5 CA 1395 uS 4. Press ∆ (up) or ∇ (down) key to scroll the reading until the displayed value matches your standard solution i.e. 1413 µS/cm. 5. Press ENTER key to confirm calibration and the LCD displays the new set reading and revert to measurement mode. 1413 uS 6. Alternatively you can abort the new calibrated value by pressing CAL key to exit from calibration mode. Important: Meter allows a tolerance range of 30% of its measured reading.
EcoScan CON 5 / TDS 5 3.3 Temperature Calibration 3.3.1 With Temperature probe For Preselected Curve The temperature sensor included with your meter is factory-calibrated. Over time, the temperature calibration may drift and require recalibration. If you replace the probe you should calibrate temperature probe prior to Conductivity or TDS calibration. 1. Connect your temperature probe to the meter. Press MODE key to enter Temperature mode until “oC” annunciator appears in the LCD. 2.
EcoScan CON 5 / TDS 5 3.3.1.1 With Temperature probe (with Curve Selection) In the event the temperature probe has drifted too far from its original characteristic – due to age and use or if the probe is being replaced, it may be a good idea to match the probe to the best curve. There are 3 curves programmed in the unit. To choose the curve, proceed as follows: 1. Connect your temperature probe to the meter. Press MODE key to enter Temperature mode until “oC” annunciator appears in the LCD. 2.
EcoScan CON 5 / TDS 5 3.3.2 Without Temperature probe (no ATC) If no temperature probe is used, the meter compensates for Conductivity or TDS response based on a new calibrated temperature value manually set by you or at 25 oC (factory default). 1. Press MODE key to enter into Temperature mode until “oC” shows in the LCD. 2. Compare displayed value to a NIST certified thermometer or other thermometer known to be accurate. 3. Press CAL key to enter temperature calibration mode.
EcoScan CON 5 / TDS 5 4. MEASUREMENT 4.1 Taking Measurement 1. To begin measurement, rinse probe thoroughly with deionised water to remove any impurities. 2. Power on meter and the meter will automatically go into Conductivity/ TDS measurement mode. Press MODE key to select your desired mode of operation between Conductivity/TDS and Temperature. 3. Dip probe sufficiently, with the tip of probe completely immersed, into sample. Stir and tap it gently to remove any air bubbles trapped.
EcoScan CON 5 / TDS 5 5. PROBE CARE AND MAINTENANCE Keep your Conductivity probe clean. Do not strike the probe against any hard surface, and never scratch the stainless steel pins with hard material. Wash the probe thoroughly with tap or deionised water after each use. Do not immerse the probe in oily solutions. To remove oil films or oxidation, clean electrode with alcohol. Clean it with a mild detergent solution. Blot it dry. Wash thoroughly in tap water and then in deionised water.
