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.
