Simple Probe Go/No-Go Testing.

Install the 2 AA batteries in the CCProbe Interface.

Test the probes by connecting them to CCProbe running on a Palm connected to the interface. Open the "CCProbe/Data Collectors" folder..

Force Probe
1. Connect the Force Probe to Port A of the CCProbe Interface
2. Open the "Force - 20" Data Collector
3. Zero the force probe using the Tools menu option "Zero Force Probe"
4. Start collecting data.
5. Pullling on the beam should make the plot go up, pushing should make the plot go down.
6. Hang a 1kg weight from the end of the beam. The force probe response should be aproximately 9.8 Newtons +/- 10%.
Temperature Probe
1. Connect the Temperature Probe to Port A of the CCProbe Interface
2. Open the "Temperature" Data Collector and start collecting data.
3. The temperature should be about room temperature.
4. Heat the temperatture probe by squeezing it between your fingers. The temperature should rise.
Light Probe
1. Connect the Light Probe to Port A of the CCProbe Interface
2. Open the "Light - 4000 Lux" Data Collector
3. Start collecting data.
4. Place probe 20 cm from 60 watt incandescent bulb.
5. Data should be aproximately 3000 Lux, +/- 1000 Lux.
6. Stop collecting data.
7. Open the "Light - 125000 Lux" Data Collector
8. Start collecting data.
9. Place probe 20 cm from 60 watt incandescent bulb.
10. Data should be aproximately 3000 Lux, +/- 1000 Lux.
VoltageCurrent Probe
1. Connect the Voltage/Current Probe to Port A of the CCProbe Interface
2. Test Voltage Measurement
  1. Open the "VoltageCurrent - Volts" Data Collector and start collecting data
  2. Connect the red and black wires together
  3. Measure the voltage, response should be 0 volts, +/- 0.2 V.
  4. Connect red wire to + terminal of 9V battery
  5. Connect black wire to - terminal of 9V battery
  6. Response should be 9 volts, +/- 5%
3. Test Current Measurement
  1. Open the "VoltageCurrent - Amps" Data Collector and start collecting data
  2. Without a current the response should be 0 Amps, +/- 0.1 A.
  3. Connect (-) terminal of 9V battery to yellow clip
  4. Connect (+) terminal of 9V battery to one lead of 10 Ohm heat cell
  5. Connect the other lead of 10 Ohm heat cell to green clip
  6. Depending on how charged up the battery is the esponse should be between 0.5 and 0.8 Amps.
SmartWheel
1. Open the "SmartWheel - Velocity" Data Collector.
2. Connect the SmartWheel to Port A on the CCProbe Interface.
3. Start the data collector.
4. Spin the smartwheel clockwize as fast as you can with a quick flip of the wrist.
5. You should see a spike to aprox 4m/s and a relatively quick ramp down to 0.
6. Spin the smartwheel counter-clockwize as fast as you can with a quick flip of the wrist.
7. You should see a spike to aproximately -4m/s and a relatively quick ramp down to 0.
8. There should be no noise spikes in the data larger than 0.1 m/s.
