502 Method
CAL LOOP pH - properties
The number of buffers and the buffer type are defined in the dialog window CAL
LOOP pH .
Command name
25 characters, [ Calibration loop pH # ]
Name of the command.
Buffers
Number of buffers
1 ... [ 2 ] ... 5
Selecting the number of buffers for the pH calibration.
Buffer type

If these buffers are used, tiamo recognizes the particular buffer automati-
cally.
Custom
An own buffer series defined in the configuration under Tools, Templates,
Custom calibration buffers can be used with Custom .
Special
If Special is selected then up to five calibration buffers can be defined di-
rectly in the dialog window of the command CAL LOOP pH .
Note
The automatic buffer recognition is inactive for the buffer type
Special . The buff-
ers must therefore be used in the same order as they have been defined in the
command
CAL LOOP pH .
Buffer # pH
-20.000 ... 20.000
pH value of the special buffers. This parameter is only displayed for Buffer
type = Special .
Note
Please note that you must enter the pH values corresponding to the measuring
temperature used. During the method run a message is displayed to indicate the
next buffer to be measured.
Request for buffer exchange
[ on ], off
If this option is enabled, a request for manual buffer exchange is displayed
after each measurement. This option must be disabled for automatic buffer
exchange when calibrating with a Sample Processor.
