Calibrating the measuring amplifier
Simulating Method (recommended)
The following instructions are referring to
a setup and calibration on-site. The
material tension will be simulated by a
weight (fig. 12).
•
Connect the first force sensor
•
Check, if a positive value is displayed
when loading the sensor in measuring
direction. If not, exchange terminals
z6 / z8 (resp. 2 / 3)
•
If used, connect the second force
sensor
•
Check, if a positive value is displayed
when loading the sensor in measuring
direction. If not, exchange terminals
z6 / z8 (resp. 2 / 3)
•
Insert material or a rope loosely to the machine
•
Adjust offset by activating the parameter function
find offset
and pressing the
↵
key
for 3 seconds. The electronic unit calculates automatically the new offset value.
•
Load material or rope with a defined weight (fig. 12)
•
Activate parameter function
calibrate feedback.
Input the force referring to the applied
weight (refer to „10. Parametrization“). The electronic unit calculates automatically
the new gain value.
•
Quit calibration with
Home
key.
