6. Turn the "POT VOLTS" switch to On.
7. Start the calibration procedure:
a. For onboard control, touch Calibrate and then Consistency.
b. For software control, select Consistency from the Calibrate menu.
8. The screen will prompt you to add weights to the potentiometer. After
you add the weight, steady the cord to minimize the amount of swinging.
Firmly tap the surface of the calibration stand to settle the weights and
stabilize the potentiometer.
When adding weights, remember that the hook weighs 50 grams.
Therefore, to test the potentiometer at 200g, you only need to add 150g
to the hook.
9. Lift the weight about two inches directly upward and release it. Allow it to
fall straight down. When the reading stabilizes, touch the ">" button click
"Next".
10. Continue adding weights when prompted.
11. After all weights have been recorded, the results will display on the
screen.
The API specifies that each calibration point must be within 5 Bc of
the standard. If any calibration point is outside this range, the entire
calibration will fail.
