## Questions & Answers

**Q: What's the max peak-to-peak voltage?**
A: Hi Jerry, it's 10Vp-p (into 50 Ohm load).  plus/minus 20% at max. position.  Below is the datasheet for your review.http://www.jameco.com/Jameco/Products/ProdDS/2160411.pdf

**Q: Can this work on 240V? as on the back it say 120V, but in the description and in the manual it say 120/110/220/240V?**
A: Back of my unit is labeled "120V". Its possible you can open it up and switch ranges, but its not a full range power supply.

**Q: is the square wave duty cycle adjustable?  if so what is the range?**
A: Yes, the duty cycle of the square wave (default is 50%) can be adjusted from 25% to 75% (See page 23 of the included user guide).

**Q: Does this include hand-electrodes (stainless steel)?**
A: This function generator comes standard with Probe-GTL-101 x 1, and yes, stainless steel.
