120Ion Operation: About Ion MeasurementXL25, 50 and 60 metersThe accumet XL25, XL50 and XL60 meter offers you unparalleled versatility with respect to ionanalysis.You can choose:• one of 6 methods of analysis• the specific electrode you will be working with• the units that you would like the meter to use when reporting the ion concentrationThe Ion Measure screen displays the direct readout of sample concentration in the desired units,as well as the time and date of the last calibration. The standards used in the calibration and theslope of the electrode are also displayed on the screen. It is important to note that theconcentration reported by the meter is actually the concentration of free uncomplexed ions in yoursolution.Connect the electrodes you will be using to the meter.Remember to setup your Ion measuring mode parameters. Refer to Ion setup section forinstructions.
