Creating a New Calibration using a Single Point

This calibration method defines a new y-intercept, leaving the existing slope unchanged.

Adjusting a barometer to match the local barometric pressure is a good example of using

the Single Point calibration. The example below is using a force sensor connected to a

LabPro.

1. From the EasyData main screen, select Setup, and

then select CH1: (or the appropriate channel).

2. Select

from the Sensor Setup screen.

3. Select

. A menu is displayed showing the different

4. Select Single Point Live….

5. Place your sensor into the necessary condition for the

calibration point (e.g. a force sensor with a known mass

hanging from it). Monitor the displayed Potential (V).

When the value is stable, select

6. Enter the known value for the calibration condition (e.g.

1.96 N for a 200 g mass), and select
