Download Hall Effect Sensor PCB Test Plan

Equipment Needed:
● DC Power Supply: HP/Agilent/Keysight - E3631A
● Oscilloscope: Tektronix - TDS 2012C
● Multimeter: HP/Agilent/Keysight - 34401A
● Magnet with known field strength
Drawings/Documentation Needed:
● Sensor Board Drawing
● Sensor Board Assembly Plan
Testing: (See Arduino pinout diagram)
● For a guide to how to wire the board properly see the assembly plan associated
with this part
● Note: Pins 3 and 4 on the INPUT block are not used!
1. Once the board is assembled properly, testing can begin
2. With the power supply turned off, connect the ground from the supply to the GND
input.
a. The GND input is the second pin on the input block “Inputs.”
3. Without any connections to the power supply, hit the limit button. This will allow
the voltage settings to be set, along with setting current compliances. With the ±6V
output selected, set the voltage to 5V and the current compliance to 0.100A.
4. Connect the 5V output of the supply to the VDD input.
a. The VDD input is the first pin on the input block, “Inputs.”
5. Connect one of the output pins (OUTPUTS Pins 1-4) to the oscilloscope.
6. Connect the multimeter to one of the pins on the corresponding test point (SV1-4).
a. Each of the test points has three pins.
b. One is connected to the ground, one is connected to the live, and one is
connected to the output
7. Turn on the DC supply voltage. The VDD LED should turn on.
8. Now monitor the output on the oscilloscope. If there is no output, troubleshoot using the
test points to find the failed component.
9. Move a magnet closer and farther from the sensor of interest. The output should change
depending on the magnets distance from the sensor.
10. Verify that the oscilloscope output matches the voltage output for the corresponding
magnet strength.
11. Test each of the 4 sensors on each board.
