00:00:01.867 --> 00:00:10.476
You will need to set the baseline value to zero
before using the force sensor.

00:00:10.531 --> 00:00:14.817
Select Zero Inputs on the data panel.

00:00:14.862 --> 00:00:21.087
Select Start to check the baseline is now at zero.

00:00:21.112 --> 00:00:25.755
Select Stop.

00:00:25.800 --> 00:00:36.017
Select Start to record for 5 s with no weight on the force sensor.

00:00:36.020 --> 00:00:41.011
Hang a known weight (between 5 and 10 g) from the force sensor.

00:00:41.024 --> 00:00:47.016
Allow the weight to settle and keep recording
for another 5 seconds, then select Stop.

00:00:47.016 --> 00:00:55.004
Use the region selector to highlight a stable region of the recording
before the weight was added.

00:00:55.100 --> 00:00:59.017
Select the arrow next to Value 1 in the Units Calibration panel.

00:00:59.149 --> 00:01:03.629
This is your baseline value, which corresponds to zero millinewtons (mN).

00:01:03.720 --> 00:01:06.620
Use the region selector to highlight a stable region of the recording
after the weight was added.

00:01:06.660 --> 00:01:10.416
Select the arrow next to Value 2 in the Units Calibration panel.

00:01:10.920 --> 00:01:23.172
To work out the Force (mN) for Value 2 use the Conversion table.

00:01:24.160 --> 00:01:26.777
Enter the calculated value for your weight in
millinewtons (mN) into the box for Value 2.

00:01:26.895 --> 00:01:29.000
Select Calibrate.

00:01:29.048 --> 00:01:34.632
Now your Force channel should show the units mN, not mV.
