## Questions & Answers

**Q: Can you tell me how to place the battery and which direction the positive terminal is facing?**
A: Positive side up

**Q: How long does it take for the probe to be left in the fish tank to display the temperature? Why does it always show 24.3 degrees on your tape?**
A: It should start picking up the temperature straight away so after 5 minutes (probably very much less) it should be giving the correct temperature.
24.3 is just the temperature shown on the box, wouldn't make a lot of sense to show a blank screen 🤔
