## Questions & Answers

**Q: My normally closed sensor doesn’t appear to have power when there’s no current so relay doesn’t stay closed. Am I missing something?**
A: This is an electronic switch, using a multimeter to measure the on-off measurement can not be measured, you must connect the load test, such as current relays, LED lights to test the on-off

**Q: ordered 2 of the "NC" units niether one has continuity between the contacts when no currant is flowing. Did i get bad ones or is this somehow normal?>**
A: I purchased the Normally Open style, so this answer is not based on the exact same type of unit.  The device description states that the unit has a "solid state output", which may very well indicate that it is not a relay-style contact.  The output may be a triac device - similar to a lamp dimmer but either fully on or fully off.  Try the lamp test (using a lamp that draws less than the 0.3 amps rated) to make certain the unit(s) work as expected. A standard night-light (4 to 7 watts or so) would work fine.  (Caution - don't use more than about a 40 watt lamp for testing as you run the risk of exceeding maximum load current.)
