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.

.. image:: /image/NIMAX(1).svg

* 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)

#. Signal Input Range---> Max: 10, Min: -10, Units: Volts
#. Terminal Configuration---> Differential
#. Custom Scaling---> No Scale
#. Acquisition Mode---> Continuous Samples
#. Samples to Read---> 800
#. Rate(Hz)---> 2000
#. Leave other options to default
#. 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.
