Support of Pfaudler Sensors<br />
or pH sensors with a zero point other than pH 7 and/or deviating slope,<br />
e.g. pH sensors with a zero point at pH 4.6<br />
This requires an additional function (TAN). The option is enabled in the<br />
SERVICE / OPT: PFAUDLER menu (see page 148).<br />
For Pfaudler standard pH sensors, you can specify a nominal zero point and a<br />
nominal slope.<br />
In addition, you can enter a pHiso value.<br />
The additional entries appear in the CONFIGURATION / SENSOR menu:<br />
SNS: NOM ZERO (default: 07.00 pH)<br />
SNS: NOM SLOPE (default: 59.2 mV)<br />
SNS: <strong>PH</strong>_ISO (default: 07.00 pH)<br />
Prior to measurement, you must enter the values for nominal zero and slope and<br />
the isothermal intersection point pHiso as provided by the manufacturer and<br />
perform a calibration using suitable buffer solutions.<br />
When you use a Memosens Pfaudler sensor, the data will be read from the sensor or<br />
will be set to standard values. Here, you do not have to make entries. The respective<br />
menu items will be suppressed.<br />
The nominal ZERO/SLOPE values are required for the proper functioning of the<br />
sensor monitoring and calibration functions (Sensoface, Calimatic), they do not<br />
replace an adjustment (calibration)!<br />
