criteria

Acceptance criteria = Yes
Enables the user to enter preset minimum and maximum values for
measurement results. If the result lies outside these values an alarm
message appears and the results are rejected by the instrument. The
Supervisor is the only person allowed to accept a result that has been
rejected by the instrument,
205.
Therefore, acceptance limits can be set on:
• the conductivity cell constant,
see "Min. cell cst - Max. cell cst", page
• the result value such as a pH, a potential, a concentration,
see "Minimum value - Maximum value", page
• the response slope of a pH or an ISE electrode,
see "Min. sensitivity - Max. sensitivity", page
• the pH0 of a pH electrode,
see "Min. pH0(25) - Max. pH0(25)", page
Acceptance criteria = No
The Supervisor or Routine user is free to accept/reject the results.

Irrespective of the Yes or No option selected for the
Acceptance criteria parameter:
•Acceptance limits must be set for the sample or the
standard measured temperature,
see "Min. Temp. - Max. Temp.", page
see "T°C minimum/maximum value", page
•A minimum limit is set by the instrument for the concentra-
tion measured by an ISE Direct measurement method. This
limit is the C
see "Minimum value - Maximum value", page
•A maximum limit is set by the instrument for the concentra-
tion measured by an ISE Direct or Standard addition
method. This limit is set to 10
