## Questions & Answers

**Q: Maximum voltage rating ?**
A: I have only used this on 24VDC systems.

**Q: Does this item come with test leads?**
A: No, just the box. It uses standard banana test ends.

**Q: How would you set this to, say, 350 ohms? Or any value containing a digit greater than 4? Just don't?**
A: The values are cumulative, to get 350 Ohms you would switch the 300, 40, and 10 OHM down. To get a greater the 4 value you would just switch the needed values on.  This item has a range between 1 to 11,111,110 Ohms

**Q: Will this unit  provide a stable  signal on automotive circuits?**
A: This is a typical decade box that will provide the resistance you need for testing purposes. I have used it to simulate different devices in the testing of DC control systems.
