4-6. Equivalent Input Calibration
1. Toggle the Equivalent input calibration bit (10th bit of n CH) from 0
→
1.
2. F130 starts Equivalent input calibration procedures when it acknowledges an ON edge (0
→
1)
of the Equivalent input calibration bit.
3. Toggle the Equivalent input calibration bit (10
th bit of n CH) back to “0”.
4-7. Calibration Error
If calibration operation is performed without properly making strain gauge type sensor input or
initial setting to the F130, a calibration error occurs. Check the calibration error number (n+7 CH),
remove the cause, and then perform calibration operation again.
When the calibration error occurs, "1" is returned to the 11th bit of n+1 CH "setting error
occurrence."
Calibration Error 2
This indicates a state in which Zero calibration cannot be performed because an electric signal
exceeding the input voltage range is input on the positive side. Check the cable for breaks or wrong
wiring.
Calibration Error 3
This indicates a state in which Zero calibration cannot be performed because an electric signal
exceeding the input voltage range is input on the negative side. Check the cable for breaks or wrong
wiring.
Calibration Error 5
Sensor
rated capacity value is preset to “0”. Select a proper non-zero value.
Calibration Error 6
The output of the strain gauge type sensor is too small to perform calibration. Check to see if load is
applied properly, or the strain gauge type sensor has such a capability that can make appropriate
output, and then perform Span calibration again.
Calibration Error 8
Strain gauge type sensor output is outside the F130
’s allowable
sensor input range. Check if the
sensor is properly loaded, and the its rated output falls within the F130
’s
sensor input range.
Perform Span calibration again. Then, perform Span calibration again.
