Appendix G: Functional Test for Cyclops with no Connector
To perform a functional check on the Cyclops, connect the Cyclops colored wires to
the power supply and multi-meter as shown in Figure 2 below.
No Connector Cyclops (P/N: 2110/2100-000-
“Identification Letter”-NC)
Additional Equipment required for functional tests:
DC Power Supply, 3 - 15 VDC, >100 mA
Multi-meter to read 0
– 5 VDC
Note: Supply voltages greater than 15 VDC will result in damage to the
sensor.
Figure 2.
With the Cyclops connected as shown in Figure 2 answer questions 1-3 by making
the following functional tests:
1. Is the LED on?
Hold a piece of white paper about ½ an inch in-front of the optical head to
ensure the LED is on.
Note: Cannot perform this test for Turbidity
sensors because they use IR which is not visible.
2. Is there voltage output?
The multi-meter should be reading some voltage >0 VDC
3. Does the voltage output change?
Move the light source closer to your hand or a surface and check if the voltage
output increases
