## Questions & Answers

**Q: how long will it run on 2 9 volt batteries?**
A: That will depend very much on the use you make of it; we have used the same batteries for several weeks now, but the use is intermittent and for testing or commissioning only.

**Q: Can someone please give a detailed explanation of how to use and generate a signal with this device?**
A: This is used to simulate either a 4-20ma or 0-10vDC signal in a test environment, selectable via on board switch. I have found that depending on the input resistance of your load using 9 volt batteries in series may not have enough capacity so I use a small 24vDC power supply to power the generator. Connect your generator power wires & appropriate output wires observing the correct polarity & you should be fine

**Q: I see there is a place on the pc board for an on off switch.  can this be added?**
A: Not sure.  When power is applied to the terminals, the meter comes alive.  Not sure if the printed circuit card pads will turn off the meter, as I do not see any jumper or other means that is completing the circuit.  I am just disconnecting the power to turn the meter off.

**Q: When providing power to this product, what is the input voltage?  does it accept a vdc voltage range?**
A: The input voltage to this device is 24VDC, and have an analog output 0-10Vdc or 0-20mA. Works really good.
