00:00:01.867 --> 00:00:06.312
You will need to set the baseline value to zero.

00:00:06.428 --> 00:00:10.476
If you are using the teaching force transducer or Bridge Amp:

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

00:00:14.862 --> 00:00:24.541
Select Start to check the baseline is now at zero.

00:00:25.901 --> 00:00:28.750
If you are using the Bridge Pod:

00:00:28.828 --> 00:00:33.489
Select Start to record in the data panel.

00:00:33.514 --> 00:00:39.088
Use the knob on the front of the Bridge Pod to zero the signal.

00:00:39.140 --> 00:00:42.056
Select Stop.

00:00:42.157 --> 00:00:46.437
Hang a known weight (between 5 and 10 g) from the force transducer.

00:00:46.489 --> 00:00:55.655
Allow the weight to settle and keep recording
for another 5 seconds.

00:00:55.786 --> 00:01:10.786
Use the region selector to highlight a stable region of the recording
before the weight was added.

00:01:11.370 --> 00:01:15.466
Select the arrow next to Value 1 in the Units Calibration panel.

00:01:15.682 --> 00:01:20.639
This is your baseline value, which corresponds to zero millinewtons (mN).

00:01:20.874 --> 00:01:26.369
Use the region selector to highlight a stable region of the recording
after the weight was added.

00:01:26.608 --> 00:01:30.040
Select the arrow next to Value 2 in the Units Calibration panel.

00:01:30.847 --> 00:01:38.504
To work out the Force (mN) for Value 2 use the Conversion table.

00:01:38.620 --> 00:01:43.530
Enter the calculated value for your weight in
millinewtons (mN) into the box for Value 2.

00:01:43.557 --> 00:01:45.327
Select Calibrate.

00:01:45.410 --> 00:01:48.994
Now your Force channel should show the units mN, not mV.
