## Questions & Answers

**Q: I have a toaster which occasionally trips my breaker. Will this respond quick enough to see amps drawn to determine if toaster problem?**
A: Thank you for your question.

You can get the below data with this watt meter:

Cumulative Value
√ Accumulated Time (only accumulate the time when the measured device is using power)
√ Electricity Consumption
√ Cost (need price setting)

Instantaneous Value
√ Watts
√ Amps
√ Voltage
√ Frequency
√ Power Factor

Peak Value
√ Max. Watt
√ Min. Watt

It doesn't record the instantaneous time so it doesn't work in your application.

Please feel free to let us know if you have more questions.

**Q: Can it read start up watts?  Up to 2000 W? Does it save the value?**
A: It does measure and track min and max wattage, but I'm not sure if it would read or track surge watts (as they are usually a fraction of a second)
Product description says the range is 0-3680W (30 amps at 120v), but after running my desktop computer (less than 700w) for a few minutes, it started to give off a burnt electronics odor.

**Q: Can I use to accurately measure inrush current? Does it register and save such brief spikes in current?**
A: Thank you for your question.
Here are some notices when using the watt meter.

1. This power monitor meter can measure 110-130 Vac & 200-240 Vac voltage; 0-16A AMP; 0-3680W wattage, and indicate overload when load up to 3680W, but the label on the product back only shows low volt range due to certification requirements.

2. This wattage meter only compatible with NEMA 5-15P plug & 5-15R outlet, so you will need an extra adapter to work with other plugs.

3. This wattage meter DO NOT work with AC inverter and solar panel inverter.

This watt meter is an improved version that can measure many data and has a class 1.0 accuracy standard. I hope you like it.
If you have anything questions, please feel free to contact us.

**Q: What values do I put in the “00.00” cost/kWh. I live in New York City. I am unsure what numbers go on the left side from the “.” & on the right side?**
A: You should check your electric bill to determine the cost of KWH in NY City. Whatever that cost is, this is what you will enter. If you unsure, contact your electric utility provider and ask them, as sometimes there are multiple billing plans that may exist within the same provider and depending on your location. As a rough approximation, you can also check your last bill and simply divide the total amount you paid by the total of KWH you consumed. This may not yield the exact cost of KWH as per your utility billing plan, but should be good enough an approximation to allow you to estimate costs with the Watt meter. As to what you should enter in the meter itself, let's say your local cost is roughly $0.14/KWH, so you would enter  "00.14" in the Watt meter.
