•
Zero (mV)
After this line is pointed a new window is opened to adjust the 0mV
reference.
Usually run this operation connecting the "Short-circuited" plug on the
"MEAS" socket.
7.3 VIEW screen
Use this menu to view:
•
Last Calibration details.
•
Stored readings.
•
«Last STD Datum»
After this line is pointed the «Last STD Datum» window is opened:
It shows all information about the Buffers used for calibration.
«¬ ®» Move to next standard Buffer details.
•
•
«STD» Jumps to Calibration procedure. See XXX
•
«SETUP» Jumps to standard Buffers selection screen.
Point over
•
«Stored Datum»
This screen shows all previous reading stored by the user on the pH-
meter.
Function Keys:
•
«PRINT» If printer (See 7.6) is attached to the pH-meter starts
to print all or just the selected reading.
•
«DEL» Deletes all stored reading or just the selected one.
•
«PgUp» «PgDn» Scroll page.
Point over
7.4 STD screen (pH-Calibration)
Calibration is the process to calculate the relationship between the mV readings
and the actual buffers pH value. It is necessary, because all electrodes have differ-
ent features.
In a few words, calibration steps are:
•
Select the "Buffer Group" that is going to use. This means that you must set
what Buffers are going to be used for calibration.
•
Measure each Buffer with the electrode. On this step, the pH-meter calculates
the correction to apply from the pairs measured mV - pH.
From the starting menu, point over «STD» button to proceed with pH-meter cali-
bration.
Note: Usually a pH-meter must be calibrated:
•
First time use
•
Daily
•
After change the electrode
•
After measuring strong acids (pH<2)
•
After measuring strong alkalis (pH>12)
•
After measure very dense solutions that can obstruct the membrane.
