Fault 14, Last Calibration Failed. The
CALIBRATION LED flashes three times, pauses
for three seconds, and repeats (Figure 5-14).

when the slope and constant values calcu-
lated are out of range and the unit reverts to
using the previous calibration values.
2. The cell should be replaced. See paragraph

instructions.
