Glp Table - Radiometer Analytical MeterLab PHM220 Mode D'emploi

The data stored in the GLP table comprise the results of the last 9
calibrations and the last 25 sample measurements for pH and mV
respectively. The data are accessed in the following way:
1. Press the Mode key and select either pH or mV using the left or
right arrow key.
2. Press the GLP key.
In the display shown above, it is pH data which can be ac-
cessed. This means that pH was selected in step 1. (For
information about result data for a mV method, see page 29).
Two options are available: CAL and SAMPLE. Use the left or
right arrow key to make a selection.
Note: When the GLP key is pressed followed by the Print key a
summary of either 9 calibration or 25 sample measurements is
printed out, depending on the option selected above.
3. When CAL is selected access is gained to the following calibra-
tion data: the zero pH, sensitivity, temperature, whether a one or
two-point calibration has been performed, min. and max. pH
values, in addition to the date and time.
