Buffer #2 is
too close
to
Buffer #1
1. During pH EasyCal 4 7 10
or Standard/Slope
calibration, buffer 2 is
within 2PH of buffer 1.
2. During pH EasyCal
DIN19267 calibration,
buffer 2 is within 1PH of
buffer 1.
Check buffers.
1. Replace Buffer #2 with a
buffer of the appropriate pH
value and continue the
calibration.
2. Press “ESC” to interrupt the
calibration when “Place
Sensor in pH Buffer #2” is
prompted again. Restart the
calibration with appropriate
buffers.
Value Must
Be Larger
Than -10°C(or 14°F)!
During temperature
calibration, the entered value
is smaller than -10°C(or 14°F).
Enter the appropriate value.
Value Must
Be Smaller
Than 70°C(or 158°F)!
During temperature
calibration, the entered value
is larger than 70°C(or 158°F).
Enter the appropriate value.
Value
Too Large(or Small)!
During temperature
calibration, the entered value
is more than 25 degree away
from the detected value.
1. Check the sensor and restart
the calibration procedure.
2. Enter the appropriate value.
The HYSTERESIS is greater
than the MAX SETPOINT
Set HYSTERESIS to a smaller value
than MAX SETPIONT.
