5. Put the probe in the standard solution. Make sure that the reference junction is fully in
the standard. Move the probe up or down or lightly shake the probe to remove air
bubbles.
6. Push Read . The display shows "Stabilizing" and a progress bar as the reading
stabilizes. The display shows the value of the check standard and Check Standard
Passed or Check Standard Failed.
7. If the display shows Check Standard Passed , the check standard measurement is in
the accepted limits. Select Done to continue the sample measurement.
8. If the display shows Check Standard Failed , the measurement is out of the accepted
limits. A calibration is recommended. Make sure that the limits are set correctly at the
MTC301 probe Settings menu. If the acceptance criteria is set to "Cal Expires on
Failure: Yes", the display shows the calibration icon and a question mark until the
probe is calibrated again. To correct the probe calibration and status indicator,
calibrate the probe (refer to
Calibration on page 3).

Methods are groups of default or user-defined settings relevant to specific applications. If
the meter is set to the default method and the Modify Current Settings option is chosen, a
prompt for a new name is shown after the changes are entered. The settings are saved
with this name to distinguish them from the default method settings, which cannot be
changed. A saved method can be used instead of multiple adjustments to the individual
settings. Changes made to a user defined method are automatically saved with the
existing name. Multiple methods can be saved for the same probe on each meter.
1. Make sure a probe is connected to the meter.
