## Questions & Answers

**Q: do you have one whit an *F reading capable of reading up to 800 *F ?**
A: Sorry, we don't have.

**Q: How do you get the display to show three digits?  The one I purchased only shows two.**
A: It should work fine right out of the box. Assuming you're trying to measure a temperature greater than 10 C, you should see two digits, a decimal point, and another digit. If that's not what you're getting then I'd say you should return it for one that works.

**Q: can you cut the temperature probe wire to add more wire**
A: While it is technically possible to extend the wire for the temperature probe, it is not recommended as it will affect the measurements and this unit does not have an easy way to recalibrate. It's best to buy a K type probe of the required length.

**Q: how long is the thermocouple cable?  Can the cable be extended without affecting the accuracy?**
A: Cable is 19.68 inches (50cm) long. Sorry we only provide this length currently,But this is very good customer requirement. We will forward your suggestion to our engineer. If we can provide a longer length, we will keep you informed.
