tiamo 2.1 (ProcessLab)

Note

The automatic buffer recognition is deactivated for the buffer type Spe-
cial
and the buffers must therefore be measured at the time of calibration
in the same order as they were defined in the command CAL LOOP
pH
.

Buffer # pH

pH value of the special buffers (this parameter is only displayed for Buffer
type
= Special).

Range

-20.000 ... 20.000

Note

Enter the pH values for the measuring temperature used. A message will
be displayed correspondingly often during the run to indicate the next
buffer to be measured.

Request for buffer exchange

on | off (Default value: on)

If this check box is activated, a request for manual buffer exchange is dis-
played after each time the calibration loop is run through. This parameter
must be disabled for automatic buffer exchange when calibrating with a
Sample Processor.

The temperature-dependent pH values of several common pH buffers are
stored in the system for automatic buffer recognition during pH calibration.
In addition to the Metrohm buffer solutions 6.2307.1X0, other reference
and technical buffers are also included in the tables.

The following tables provide an overview of the stored pH(T) series:
