CONDUCTIVITY MEASUREMENT............................................................................................................... ...

conductivity, liquid resistivity, total dissolved solids (TDS) and salinity using combined 4-ring and 2-ring conductivity/temperature probes. Temperature only is measured by Pt100 or Pt1000 immer- sion, penetration or contact probes. The probe calibration can be performed automatically in one or more of the 147μS/cm, 1413μS/cm, 12880μS/cm o ...

Foreword The instrument keyboard is composed of single-function keys, like the MENU key, and double- function keys such as the ON-OFF/Auto-OFF key. In the double-keys, the function in the upper part is the "main function", while the one in the bottom part is the "secondary function". When the instrument is in standard measurement mode, the main function is active. In the menu or in conjunction with the FUNC key, the ...

mum (MIN) and average (AVG) value of the conductivity, liquid resistivity, total dissolved solids, salinity and temperature measurements, updating them with the acquisition of new samples. The acquisition frequency is once a second. Use the χ.Ω.TDS-ESC key to switch from conductivity to liquid resistivity, to total dissolved solids or to ...

urement automatically when it has been stable (within 1 digit) for over 10 seconds: the message HOLD is displayed. To perform a new measurement, it is necessary to press the FUNC/ENTER key. The HOLD message starts blinking, while the display follows the actual measurement trend, until it stabilizes again and the HOLD message remains still. In the me ...

strument will always remain on. With intervals greater than or equal to 60 seconds, it is pos- sible to turn off the instrument between loggings: it will turn on at the moment of sampling and will turn off immediately afterwards, thus increasing the battery life. Using the arrows select YES and confirm using ENTER in order to enable the automatic turni ...

values 0.01, 0.1, 0.7, 1.0 and 10 cm-1 (with tolerances from –30% to +50% of nominal value) are admitted. The cell constant must be inserted before starting the probe calibration. An ERR signal is generated if the cell constant's actual value exceeds the limits –30% or +50% of nominal value. In this case it is necessary to check that the value set is ...

strument displays a dotted line (- - - -). 13) YEAR: to set the current year. Use the arrows to modify this parameter and confirm using ENTER. 14) MNTH (month): to set the current month. Use the arrows to modify this parameter and con- firm using ENTER. 15) DAY: to set the current day. Use the arrows to modify this parameter and confirm using ENTER. 16) HOUR ...

SERIAL/EraseLOG key - only HD2106.2 In measurement mode, this function starts and stops the data transfer to the RS232C serial output. According to the settings entered in the Print and log interval menu item, a single sample can be printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be set up if Print and log interval=1…3600. The printing operation is accompanied by the ...

ductivity probes, or temperature probes. The 4-wire Pt100, 2-wire Pt1000 probes may be used for measuring temperature, which is used for the automatic compensation of the conductivity. The instrument obtains the following from the measurement of conductivity: • the liquid resistivity measurement (Ω, kΩ, MΩ), • the con ...

ter are more resistant to collisions, and so more suitable for industrial use. Cells with temperature sensor The probes fitted with built-in Pt100 or Pt1000 temperature sensor simultaneously measure the con- ductivity and the temperature: that allows automatic correction of the effect of the latter on the solu- tion conductivity. Choosing th ...

On the main display an "m" (manual) is turned on near the battery symbol (if on). The MT indica- tion is printed on the print-outs. On the other hand, if the temperature probe is present, the AT sym- bol appears. To manually change the compensation temperature press the °C/°F key once: the indicated tempera- ture value starts blinking. Select ...

2. Set the probe's cell constant by selecting it from the admitted values: 0.01, 0.1, 0.7, 1.0 or 10.0 3. Dip the conductivity meter cell in the calibration solution until the electrodes are covered with liquid. 4. Stir the probe lightly to remove any possible air inside the measurement cell. 5. If the conductivity probe is not fitted with temperature sensor, press °C/°F and, using the arrows, en ...

appears on the comment line. If the calibration solution conductivity is sufficiently close (-30% to +50%) to one of the standard solutions, the secondary line displays the value. Otherwise it displays the calculated value according to current settings. In the central line the solution con- ductivity value is indicated according to the cell constant cu ...
