## Questions & Answers

**Q: When the motor turns off, why does it show the max rpm of all time, not just the last time the motor was running? mine always says 27000 when off.**
A: Well I’m not sure why but don’t be concerned with it. Mine always says 6850 ? As long as it’s reading right when motor is running we are good and shows the hours we are good again. Good question but nothing to be concerned about. Take care !

**Q: do you have to use a wire to the sparkplug or not? Some say you can hold it close to the sparkplug and it will work and others say you need a wire?**
A: I just bought one of these. It does not read the proper rpm's without using the wire. It will get up to 6-7k then drop down to around 5600 when running at WOT. It is not what I was expecting and I didn't know that you needed to wrap the wire around the spark plug wire.

**Q: Did not come with operating instructions.  Anyone receive any with their package?**
A: RPM TYPE---- According to the gasoline engine with different power and speed range, there are 3 optional RPM types: 1P2R; 1P1R; 2P1R
It doesn't give a lot of options. But I found it works good on small engines. Rape the wire around the spark plug wire and secure. They provide a few small zip ties I used a little elec tape. 1P2R = 1 piston 2 revolutions and so on. It worked for what I needed after repairing a Gen set for both idle speed and Max RPM. One button does it all.
