## Questions & Answers

**Q: Can i use this as a one pulse per second generator?  I don't see a way to adjust frequency**
A: Hi, this device is designed to simulate voltage and current signal, can't be used as a one pulse per second generator.

**Q: how do you install a battery?**
A: It does not come with a battery but you can buy a Lipo Rechargeable Lithium Polymer ion battery pack. The battery pack comes per-wired with the proper connector. Verify the connector pin polarity is correct before connecting. I just installed the YDL 3.7V 2800mAh 623360 (https://www.amazon.com/gp/product/B07BTRLKPT/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and it works fine. To disassemble

     1.  Ensure battery switch is in the OFF position.
     2.  Remove knob from dial encoder.
     3.  Remove nut from dial encoder.
     4.  Use small screwdriver to separate top from case (slots on one end to make this easy to do).
     5.  Remove 4 screws holding pcb in case
     6.  Remove pcb and flip over. Two pin JST connector on bottom for battery pack connection (polarity is marked)
     7.  Assuming polarity of battery pack connector matches pcb connector just plug the battery pack in.
     8.  Mound battery pack in case with double back tape or velcro pieces.
     9.  Reassemble in reverse order.
The unit should power up when battery switch is placed in ON position.

**Q: Can this output a current duty cycle?**
A: Not that I’ve found. Instructions a little sparse, Nicky made unit though, and reasonably accruate, certainly for the cost.

**Q: To the manufacturer...would you consider upgraded terminal block to the quality cam lever action terminal block instead of the screw block.**
A: If one is considering a high-current application, a Cam-Lever type terminal will not provide the compression needed over a wide area for a proper connection.
