5. Select Measurement Options and update the settings:
Option Description
Resolution Sets the resolution:
•
•
•
•
•
The resolution affects the number of decimal places and the stabilization
time. Higher resolution measurements take more time to stabilize. Slower
stabilization times provide higher accuracy measurements.
Measurement Set the measurement limits—Lower limit (default: 0.00 pH) or Upper limit
Limits (default: 14.00 pH).
The measurement limits can be set to match the acceptable values for the
sample. When the measurement is above the upper limit setting or below the
lower limit setting, the meter shows an "Out of limits" message. This message
is an alert to a potential problem with the process conditions.
6. If prompted, enter a name for the new method settings. Additional changes made to the
settings of an existing method are automatically saved with the same method name.
7. Push EXIT until the meter returns to the measurement mode.
1. Make sure a probe is connected to the meter.
2. Push and select PHC301 Settings.
3. Select Modify Current Settings.
4. Select Calibration Options and update the settings:

Custom buffer sets are characterized at 25 °C (77 °F).
Buffer set values are shown on the Calibration Options screen.
Note: Only the minimum calibration points must be measured for
shown on the calibration screen.
Buffer Set If the Buffer Set is set to Customer Buffer Set, sets the custom buffer set (refer
Values to Table
Minimum Cal Sets the minimum number of calibration points necessary before a calibration
Points can be completed—1 (default), 2 or 3.
Slope Limit Sets the slope limit—1% to 10% (acceptable slope criteria, default = 5%).
The slope must fall within set limits for successful calibration.
