Torque Calibration
This operation is valid for machine types E and H only.
The
aim
of this operation is to check
and readjust the torque measurement
sensor values, this means the offset
and gain of the sensor (strain-gauge).
Note however that a type E needs to
have a correctly adjusted analogue
output (0 to 1 VDC for 0 to 10 Nm).
A window like the Figure 15 will be
displayed (for type H calibration).
Figure 15
– Torque
Calibration window
1 Torque:
Information which the “terminal measure” has to show (±5),
when the strain gauge is without any weights. If not, please
make a new zero calibration by activate the “
Calibrate
Offset
” Button. Attention: Verify before that the strain
gauge has not weight on it.
2 Torque
Information what the “terminal measure” has to show (+/-
10), when the strain gauge has the Gain weights on it. If
not, please load appropriate weight onto the load cell, fill
appropriate value into “Weight” and make a new gain
calibration by activate the “
Calibrate Gain
” button
Weight
Insert here the weight value, which is using for the gain
calibration
Terminal measure
Shows the equivalent torque for the actual ADC reading
ADC value
Indicates the actually measured value from the
analogue(digital converter
Calibrate Offset
This button allows calibrating the offset when there is
nothing on the strain-gauge.
Calibrate Gain
This button allows calibrating the gain when there is weight
reference on the strain-gauge.
Save
After the
Offset calibration
and the
Gain calibration
, you
have to save the new calibration factors with this button.
Set to default
This button restores with to default standard calibration
factors
