￭ LOW: The symbol is also shown if the measurement stability is
poor. The measured values are within 1.2 mV.
￭ MEDIUM: Measured values are within 0.6 mV.
￭ HIGH: The symbol is shown only if measurement stability is high.
The measured values are within 0.3 mV.
Default value: MEDIUM
P1.6 pH calibration values
P1.6 is used to display or print the results of the last calibration per-
formed.
VIEW
The following results are shown automatically on the display, one after the
other:
￭ Date and time of calibration, beaker with buffers used
￭ Offset value of electrodes in mV
￭ 1st slope in % in the measuring range
￭ 2nd slope in % in the measuring range (is shown only for 3 calibration
points)
NOTE
The 949 pH Meter accepts only calibrations with pH electrodes with a
slope in an acceptance range between 80% and 120%. Calibration can-
not be exits outside the acceptance range. The SLOPE OUT OF
RANGE error message appears on the display.
PRINT
The following results are printed out:
￭ Model number and serial number
￭ Date and time of calibration
￭ Offset value of electrodes in mV
￭ pH range with relative slope
NOTE
￭ Use only the original printer specified by the manufacturer.
￭ Ensure that the printer is connected and switched on.
￭ Ensure that the paper roll and the cassette are inserted correctly.
Additional information can be found in the manual for the printer.
