The first checkpoint with load is saved and you can see that rows 1 and 2 in the Deadweight calibration
window change and now read:
Number of cal points 1 and No Load on transducer respectively.
5. Remove applied torque on the transducer.
You have now completed the first full reference mV/V measurement for this transducer, both at rest and at
a specific torque value.
6. Repeat the procedure at least two more times.
When you have done this the
Deadweight calibration window should display Number of cal points 3
confirming that three full reference mV/V measurements have been completed.
7.2.2 Linearity check
When the above calibration measurement values have been recorded and saved, perform a linearity check
to see how consistent the transducer is.
A full linearity measurement or checkpoint includes a mV/V checkpoint without any torque applied over
the transducer and a checkpoint when a specific torque level is applied over the transducer using the
deadweight equipment.
The linearity check is not used for calculating the new calibration value. It is just used
to check the transducer linearity.
1. Measure and record the mV/V value of the transducer (2) two consecutive times according to the
procedure in the Calibration section above.
No. of cal points -> No. of lin. points.
2. Press the
Lin.ch menu block. The Deadweight measurement window displays the following:
Number of cal points
This is your current status of the
number of full linearity checks for your
calibration.
Load on transducer
Gives you the torque status of the
transducer
Measured value (mV/V)
This refers to the numeric value below
and represents your measured mV/V
value under the current load on the
transducer.
(Numeric value)
Below this window, three new menu blocks appear with functionality specific for the linearity check
process:
