INTRODUCTION This manual contains the operating features of this meter. At some points this manual will refer to our website www.eutechinst.com,for further explanation and background information, it will be indicated with this symbol: On this website you can also find additional information regarding applications, measuring theories and hints &...
PREPARATION Conductivity Electrode Information A 2-cell or 4-cell conductivity probe can be connected. Your meter includes a 4-Cell conductivity electrode (Part No: EC620-165) with an electrode constant of K = 1.0. This conductivity / TDS electrode features a built-in temperature sensor for Automatic Temperature Compensation (ATC).
CALIBRATION Important Information on Meter Calibration Your meter has four measuring ranges. You have an option of calibrating your meter in a single point calibration for all the 4 ranges or for better accuracy; you can calibrate one point in each of the measuring ranges (up to four points).
4.4.1 Selection of Automatic or Manual Calibration (P5.0) Automatic calibration is applicable in conductivity measurement mode only, manual calibration is applicable in conductivity, TDS and Resistivity mode. Only from the conductivity measurement mode; 1. Press setup. 2. Press save/▲ or view/▼ until you view parameter P5.0 (ACAL). 3.
Note: To exit without confirmation, press std to go back to measurement mode. Note: Ensure you set the correct TDS factor before TDS calibration. 1. Repeat step 1 to 4 from p 4.5. Both displays will show the current value. 2.
MEASUREMENT Temperature Compensation This meter can take measurements with automatic (ATC) or manual (MTC) temperature compensation (MTC for 2-Cell electrode only). Factory default is ATC on. For ATC, attach the temperature electrode. Taking Measurements 1. Rinse the electrode with de-ionized or distilled water before use. Shake or air dry. To avoid contamination or dilution of your sample, rinse electrode with a small volume of your sample liquid.
COMMUNICATION / PRINT FUNCTION Connecting the RS232C Cable The meter provides an RS232C output for transmitting readings to a p rinter or computer via a cable. The output data is in the ASCII format. This for allows the data to be imported by a variety of software that reads ASCII data (e.g.
1. Press setup 2. Press ▲/save or ▼/view until you view P12.0. 3. Press enter. 4. Press ▲/save or ▼/view to select Current or Memory data print out. 5. Press enter to confirm or std to exit from this page. Note: All stored memory will remain in the meter after printing.
2. Press save/▲ or view/▼ until you view parameter P3.0. 3. Press enter to view the current temperature coefficient value. 4. Press save/▲ or view/▼ to select the temperature coefficient of your solution. 5. Press enter to confirm or std to return to the measurement mode. Setting the normalisation temperature (P4.0) Your meter will normalize its conductivity measurements to a standard temperature that you can select.
Cleaning the meter The meter requires no regular maintenance, but it is recommended to occasionally wipe down the front with a damp cloth from time to time. Electrode Care 1. Keep the electrode clean. 2. For best accuracy, soak a dry electrode for at least 5 to 10 minutes before calibration. 3.
