Calibration Procedure
1.
Activate web interface (ref. to chapter 8.1) and call web page „Offset/Calibration
over the web browser” (see chapter 8.3).
2.
Connect volt meter to the voltage output (Fig. 2, terminal 13/14)
3.
Connect first force sensor to the amplifier (see Fig. 2).
4.
Check whether a load in measuring direction (red point) results in a positive volt
reading. If the reading is negative, change signal wires in the corresponding sensor
(Fig. 2, terminals 6/7).
5.
If applicable, connect second force sensor.
6.
Check whether a load in measuring direction (red point) results in a positive volt
reading. If the reading is negative, change signal wires in the second sensor (Fig. 2,
terminals 10/11).
7.
Unload measuring roller by removing material or rope from it.
8.
Click the key „Adjust Offset“.
9.
Load the rope with the defined calibration weight (Fig. 3).
10.
Click the key „Calibrate Gain“. With that the calibration is completed.
