16 ADDENDUM 3: METER FACTORY DEFAULT SETTINGS
Resetting the meter to factory default settings clears all calibration data and most other setup
functions you might have changed. The following settings will remain as you have set them:
• Temperature unit of measure (°C or °F)
• The temperature offset calibration value.
NOTE
DO and pH data are cleared separately from each other.
• To clear pH data, see Sub group P4.0 on page 36.
• To clear DO data, see Sub group P7.0 on page 49.
Type Parameter P No. Default Remarks
