Street Light Shorting Caps

Testing a twist lock photocell with a multimeter involves a few straightforward steps to ensure the photocell is functioning correctly. First, remove the twist lock photocell from its socket and replace it with a twist lock photocell shorting cap or a twist lock shorting cap to maintain the circuit continuity. Set your multimeter to measure resistance (ohms) and connect the multimeter probes to the photocell’s terminals. In daylight or under a bright light source, the resistance should be high, indicating that the photocell is in the “off” state. Conversely, in darkness or when covered, the resistance should drop significantly, showing that the photocell is in the “on” state. If the readings do not change as expected, the photocell may be faulty. Using a photocell shorting cap or a street light shorting cap during this process ensures that the street light system remains operational while testing is conducted.
