11.0 Error messages
An error message will only appear following pH calibration failure.
‘Err’ will be displayed for a few seconds then the display will show the previous
reading. Successful pH calibration indicators will disappear. The Bluelab Soil pH
Meter is in an uncalibrated state, therefore recalibration is required. See causes
of Error messages below.
Possible causes for an ‘Err’ message:
• Calibration solutions contaminated
• Wrong solutions used
• pH probe contaminated
• pH probe not properly attached
• pH probe worn out or damaged
• Calibrate to pH 7.0 FIRST then to pH 4.0/10.0
