User questions & answers

Question:	Can I use it on a gas dryer that takes 30 Amps for a split second to start? I know it runs below 8 amps once started
Answer:	Its a crap shoot as to whether this meter can handle the surge current of start up. Maybe itll work once, twice, a few times. But eventually it WILL fail. Id recommend one of those add in power monitor displays with a split core transformer that is clamped around the input hot line to sense current. For example, a CrocSee CRS-022B. Much, much safer. And can sense up to 100A!
Question:	can be used connecting 220 Volts at 60 Hz
Answer:	Yes, this item is designed for 110-220v, 50-60hz, AC power.
Question:	Can you plug space heaters into it safely
Answer:	It depends, the max. wattage rating of the PN2000 is 1760w @110v or 2000w @125v (16 amps). As long as your space heater rating is lower than this, it should work. Most space heaters have a max. output of 1500W, so you should be good to go. Note: Due to the large start-up amps of space heater, though device has abilities to deal with it, we still recommend not to use the device near the max rated specs (in most cases, the true RMS Current will be around 15A) for a long time to avoid any unexpected damage or accident. And please kindly know that the inner and outer device material is fireproofing. If device is over used or exposure to excessive heat, it may cause a melt incident but it won't start a fire. Still, you need use this device carefully to avoid any fire hazard.
Question:	Does it tell you how much electricity has been used in 24 hours and the cost of usage
Answer:	Yes, it will give a total usage over any time period (loose power circuits will be fine, consumption kWh will be kept in memory). So you just need to let it run 24 hours and check the Electricity Consumption (EC). Regarding the cost of usage, you have to do the math. Here gives you an example: Let's say your billed KWH is 0.07 and the distribution charge is 0.04. Then the KWH charge $0.07 + distribution charge $0.04 = $0.11 per Kilowatt Hour(kWh) usage. So if your device is using total 2.4 kW-hrs(EC) per 24 hours (which is equal to 100 watts in one hour), then you are paying $0.11 per kWh * 2.4 kilowatts per day = $0.264 for each day of use. Hope this explains it better.

Answer:	Being drawn-instant reading
Question:	If it is plugged for 9 hours, and ct will tell me 9hr and kwh 0.25, does it means that in 9 hours it has used 0.25 kwh or i need to multiply 0.25 x
Answer:	Hello, it means it has used only 0.25kwh in 9h.

User questions & answers

Question:	Does it read the current amps being used
Answer:	No, I had mine on and off,and it kept the count.
Question:	Can I plug it into a 20 amp outlet
Answer:	Si funciona pero solo en una dirección. Si se trata de un inversor para sistema solar y requiere medir en las dos direcciones, no funciona, tenemos otros para eso, estos dos, el primero para 120V y el segundo sirve desde 120V hasta 480V, más flexible: 1) Smart KWh meter 120V USA Mkt. 100 Amps. Single phase 2 wires Energy anylizer with Modbus RTU Amazon.com/dp/B07D49N8FH 2) Smart Energy Meter 1 2 or 3 Phase 120V/480V. Modbus. Amazon.com/dp/B07V8LBLLJ
Question:	How does this calculate cost? I need enter the current rate of my utility provider
Answer:	I don't think this meter reads backwards. I would try this one for one phase: https://www.amazon.com/Smart-Single-Energy-anylizer-Modbus/dp/B07D49N8FH/ref=mp_s_a_1_2?ie=UTF8&qid=1548534471&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=120v+smart+meter+beyondtech&dpPl=1&dpID=41OYtQPoISL&ref=plSrch
Question:	Is there a limit to the environment used? For example, where the temperature is relatively high
Answer:	Yes, up to 100 Amps, so even if the water heater is 120V then 120 x 100 = 12000 Watts Max. Most likely your heater is for 240V then the max watts in that case would be 240 x 100 = 24000 Watt. So in either case the Amps will be within the meter's range of 100 Amps. In other words, what matters for the meter is the Amps. They have to be less than 100 Amps. In you case 4500÷120=37.5 Amps. Or most likely 4500÷240=18.75 Amps. Even better.

User questions & answers

Question:	Can you force the backlit to stay on all the time? (so I don't have to keep pressing a button
Answer:	It is an offline data logging tool. If you want remote logging, I would look at VeSync Voltson.
Question:	Can I plug A light into this and see what the wattage is? if I adjust the wattage while connected will the unit adjust and read the current wattage
Answer:	No. 120 V only. 1800 W max.
Question:	Could we use this for remote data logging of total watts/hours to a computer or cell phone
Answer:	Use the setting that reads (1.5 v or 10 v). It is accurate but be aware that rechargeable batteries are 1.2 volts and the reading won't match the scale. FYI, it will still be accurate .
Question:	Can this handle a 1200 watt 240 volt PSU
Answer:	There is a strut, if I remember correctly. I gave it as a gift
