NI MAX software setup

NI MAX software acts as an interface between Hardware Setup and OM software. Here is where we set acquisition parameters for equipment test. Following are the instructions:

• Double click on NIMAX icon on Desktop or do it from start menu. Following window appears.

• Double click on Data Neighborhood in the window to the left shows NI-DAQms Tasks—> Create a new task with the mouse right click—> Add Acquire Signals, then Analog Input—> Choose Voltage—> under Supported Physical Channels use Ctrl or Shift to select the Hammer and the Accelerometer connected to NI Board (in the case of figure below, it was ai3 and ai7).

• Now, its time to set acquisition parameters for both the sensors and test them. Once MyVoltageTask window opens—> go to configuration—> Voltage_0(Accelerometer)

1. Signal Input Range—> Max: 10, Min: -10, Units: Volts
2. Terminal Configuration—> Differential
3. Custom Scaling—> No Scale
4. Acquisition Mode—> Continuous Samples
5. Samples to Read—> 800
6. Rate(Hz)—> 2000
7. Leave other options to default
8. Click on Save, to save this configuration

Note

Similar configuration may be used for Voltage_1(Hammer).

• Then, to test the Hammer—> Click on Run—> Gently strike the table with the hammer, spike should occur in the graph as shown in the following figure

• Similarly, to test the Accelerometer—> Click on Run—> Gently tap the beam with your finger—> Inspect the Accelerometer response in the plot window, oscillations should occur at the time points as shown in figure below:

Note

It is important to save the configuration as you change them.

That ends NIMAX software Setup
