mode. Under start mode, press 'MEAS' key, you can also make known addition measurement.
Firstly you need to set some parameter which is displayed as follows:
On upper side of the screen is the adding volume. The volume before adding is the sample volume.
'STD Conc' means the concentration value of added standard solution. The relevant concentration
unit is listed on right side. The displayed concentration of standard solution is 100mol/L. In the
middle of the screen is blank concentration value (Cblank). At the bottom is previous STD. On
right side is 'ENTER', 'CANCEL', 'BLANK' and 'STD' key.
According to practical condition, set the parameter of present known addition measuring mode, if
next adding volume is 1.5mL, then you can operate as follows: press once in displayed 'adding
volume' area, meter will open the input window automatically which is displayed as follows:
You can set other parameter in sequence according to above method, press once on 'ConcUnit' to
select the concentration unit of standard solution. When you select it, the color of 'ConcUnit' is
opposite (displayed concentration unit is 100.0mmol/L). When setting finishes, you can press
'ENTER' to start known addition measuring. Press 'CANCEL' to quit setting and return to start
mode.
From here, if you want to re-calibrate electrode, you can press 'STD' key, meter displays
'Calibrate Electrode?' press 'STD' again to calibrate electrode. (Please refer to chapter 'pX
Electrode Calibration' for detailed calibration method).
