CAL. ERR 3
Subtracted value for initial dead load shows a
negative value. Check if the cell is loaded in
correct direction and connections for +SIG and –
SIG are not reversed.
If the error message (CAL.ERR.3) persists even
if loading direction and sensor connections are
correct, re-calibration is required after shifting
zero point by connecting a resister across the load cell’s –EXC and –SIG terminals. Use
the resister-input relations shown in the table in “Calibration Error 2”.
CAL. ERR 4
A larger than [CAPACITY] value is specified
for [BALANCE WEIGHT] or span calibration
value.
Adjust [BALANCE WEIGHT] or [CAPACITY]
value and try span calibration again.
For accurate span calibration, it is recommended
to set [BALANCE WEIGHT] value between 50-
100% of [CAPACITY].
CAL. ERR 5
[BALANCE WEIGHT] or span calibration value is set to zero. Modify [BALANCE
WEIGHT] to an appropriate value.
CAL. ERR 6
The load cell output is too low for the F805AT-BC to perform proper span adjustment.
Check if the cell is properly loaded and capable of outputting sufficient magnitude of
signal for calibration, and try zero calibration again.
CAL. ERR 7
The load cell output has negative voltage. Check if the load is applied to the load cell in
normal direction or the connections (+SIG, -SIG) are reversed, then try span adjustment
again.
CAL. ERR 8
The load cell output goes beyond the span-adjustable range of F805AT-BC. Check if
the cell is properly loaded and its rated output range falls in the F805AT-BC’s span-
adjustable range, and try span adjustment again.

Span adjustable range for F805AT-BC is from 0.3 to 2.0mV/V.
F805AT-BC cannot be span-adjusted if the loaded load cell output does not
reach this range.
