Step
Set the power supply voltage at 15 to 16 V
9.1.5
Set the current limit on the power supply to 3.5 ± 0.1 A.
9.1.6
Set the timer relay to apply power for 1.40 ± 0.05 s.
9.1.7
If using the recommended Timer set it to 'D: One shot'.
Adjust Oscilloscope to properly capture all channels. Verify
9.1.8
1. Voltage scale (V/div) on Ch. 1 & 3
2. Current scale (A/div) on Ch. 2 & 4
3. Current probe scale matches oscilloscope (V/A) on Ch. 2 & 4
4. Current probes are zeroed
5. Vertical trigger level and channel (Ch. 1 recommended)
6. Horizontal trigger position
7. Horizontal time scale (s/div) will capture entire duration
Turn on the power supply output. Then activate the timer relay. Verify the
9.1.9
following:
1. Voltage and current were recorded per step 9.1.1
2. Measured voltage meets requirements in step 9.1.5
3. Measured current value is approximately 1/10
4. Timer relay applies power per step 9.1.7
5. Data saves and is readable on a computer
If any parameters are not met, make the required changes and re-run the test
circuit. Upon completion of this step, the 'Power and Measurement Circuit'
shall not be changed.
Remove the 'Test Circuit' and connect the Lightband to the 'Power and
9.1.10
Measurement Circuit' per Figure 9-2. Do not apply power to the Lightband.
