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 & tips. At the final page of this manual you can find information about the specifications of this meter, warranty issues and how to return your product to us.
PREPARATION Conductivity Electrode Information Your meter includes a conductivity electrode (Part No: ECCONSEN91W/ 35608-50) Ultem / Stainless Steel electrodes with an electrode constant of K = 1.0. This conductivity / TDS electrode features a built-in temperature sensor for Automatic Temperature Compensation (ATC). Wetted parts include: •...
CALIBRATION Important Information on Meter Calibration Your meter has five measuring ranges. You have an option of calibrating your meter in a single point calibration for all the five ranges or for better accuracy; you can calibrate one point in each of the measuring ranges (up to five points). When you perform a single point recalibration, the old calibration will be replaced by the new one even if the new calibration is done in a different range from the old calibration.
Repeat steps 1 to 5 from P 4.4.1. (display shows SPC) Press MI/▲ or MR/▼ to select. “YES” activates single point calibration, “NO” activates multi point calibration. Press ENTER to confirm. Press CAL/MEAS to return to measurement mode. Automatic Calibration (For Conductivity Calibr ation Only) This procedure describes the method for calibration to a 1413 µs calibrati on standard.
MEASUREMENT Temperature Compensation This meter can take measurements with automatic (ATC) or manual (MTC) temperature compensation. Factory default is ATC on. For ATC, attach the conductivity/TDS electrode to the meter. The ATC indicator will light on the LCD. If the conductivity/TDS electrode is not properly attached to the meter or it has been damaged, the ATC indicator will blink and the temperature display will show “Ur”.

Setting the temperature coefficient (P4.1) The temperature coefficient is the amount of change in conductivity per degree of temperature; it is expressed in percent per °C. Entering the exact temperature coefficient of your solution lets you accurately compensate temperature for almost any solution.
