Appendix 4: Meter Factory Default Settings - Accumet AP85 Instruction Sheet

15. Appendix 4: 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: Conductivity/TDS and pH data are cleared separately from each other.
• To clear pH data, see Sub group P4.0 on page 32
• To clear conductivity/TDS data, see Sub group P9.0 on page 41
