Figure 5-13. Fault 13, Invalid Constant
m. Fault 13, Invalid Constant. The CALIBRA-
TION LED flashes twice, pauses for three sec-
onds, and repeats (Figure 5-13).
1. After a calibration has been performed, the
electronics calculates a cell constant value.
2. If the cell constant value is outside of the
range, -4 mV to 10 mV, the alarm will acti-
vate. See paragraph 6-2, Calibration, and
verify the last calibration was performed
correctly.
3. Power down the Oxymitter 4000 and
remove it from the stack.
4. Replace the cell per paragraph 6-8, Cell
Replacement.
