CAL. ERR. 3 (Calibration error)
Inditial Dead Load is negative.
Check that load cell is mounted in the correct direction; check that load is being applied to the load cell
in the correct direction ;check that the +SIG. and -SIG. lines are propely connected.
If CAL. ERR. 3 still displayed, connect a resistor between -EXC and -SIG. load cell connections. This
should shift the Zero point. Do Zero Calibration again.
CAL. ERR. 4 (Calibration error)
The Balance weight is larger than the Capacity.
Re-enter the Balance weight equal to or less than the Capacity. Do Span Calibration again.
Balance weight must be between 50% to 100% of Capacity in order to do Span Calibration correctly.
CAL. ERR. 5 (Calibration error)
The set Balance weight is “ 00000 ” . Set adequate value to Balance weight.
CAL. ERR. 6 (Calibration error)
The loadcell output dose not reach the Span range of the F805AT-CK.
Check how load is applied to loadcell; check loadcell has sufficient outpul (mV/V) to reach Span
range. Do Span Calibration again.
Connect the resistor
between -EXC and -SIG.

The span adjustment range of F805AT-CK is between 0.3mV/V and 2.0mV/V.
Span Calibration is not Possible if load cell output is not within this range.
