Appendix 4: Meter factory default settings
Resetting the meter to factory default settings clears all calibration data and most other set up 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: Conductivity/TDS and pH data are cleared separately from each other.
• To clear pH data, see Sub group P4.0 on page 30
• To clear conductivity/TDS data, see Sub group P9.0 on page 37
