7.5 Calibrating the measuring amplifier
Proceed the calibration for each channel as follows:
•
Connect gauge to the tension- resp. current
output.
•
Connect the first force sensor
•
Check, if a positive output signal is appearing
when loading the sensor in measuring
direction. If not, exchange the two signal
wires of the referring force sensor in the
terminal block.
•
If used, connect the second force sensor.
•
Check, if a positive output signal is appearing
when loading the sensor in measuring
direction. If not, exchange the two signal
wires of the referring force sensor in the
terminal block.
•
Insert material or a rope loosely to the
machine.
•
Adjust the offset trimmer of the referring
channel until the output value is zero.
•
Load material or rope with a defined weight
(fig. 10).
•
Adjust the gain trimmer of the referring channel until the output value shows the needed
value (for ex. 10V corresponding to 500N).
Note
If the measuring amplifier is operated with fixed gain and offset, signal conditioning has to be
done with additional equipment (for ex. PLC).
