## Questions & Answers

**Q: Am planning to use an external ct. what ct ratio should i use? any recommendations?**
A: hi, The CT is designed to built inside the product. you can't use external ct.  As you can see in the picture, there is a hole in the meter. The CT is built around the hole inside the meter. The wire go through the hole is equal to go through the CT.

**Q: Can the KWH be reset?**
A: yes， it can be reset.
When powered off, the meter can save the value of electric energy and electric energy of cumulative time, and go on cumulating data when the meter is powered on again. 
When the meter is displaying electric energy, you can press down SAM CK button to reset the electric energy and electric energy of cumulative time to zero.

**Q: Can i use this to monitor voltage, amperage from a conventional residential electrical panel to a standard 3-prong outlet?: 120v 50 amp breaker 60hz?**
A: Yes as long a it's single phase. The unit has two small screw terminals for power to the unit and voltage sampling. And a 3/8" hole through it top to bottom with an inductive ampmeter coil. You just pass your hot wire through the hole and it samples the amperage. It will easily fit a #6 wire.

**Q: What would be the connections for a US 240 V without neutral?**
A: You still have to run a neutral to it or a ground.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good, accurate little meter!
*by J***H on February 3, 2021*

Initial:This is a small DIN rail mountable multi power meter.Cosmetically, it looks pretty nice. The LED displays are bright and easily legible even through a smoked plastic cover, such as the one I will be installing it into for its final home.The lower wattage/kwh display is green, to make it visually distinct when glancing at the panel.The main power feed comes in to the two bottom terminals.The meter uses this both to power itself and to measure incoming voltage.Current measurement is accomplished using a current tap loading coil permanently installed in the meter. I see no provision to "upgrade" this.From there, the meter is able to calculate a diverse range of electrical device parameters.> Voltage: Line incoming voltage at the meter. Fixed point, XXX.X, ranges across the safe operating capabilities of the meter.> Current: Detected amperage through the current coil. Fixed point, XXX.XX, 0.1-100A.> Watts: Real power determined between the detected voltage and current values. XXXX.X, MAY be floating point but my test setup cannot pull that much power safely.** Press the front panel button to switch displays.> Power Factor: The meter is able to judge the phase relationship between voltage and current, and use this to determine the power factor of the load. Fixed point, X.XXX.> Run Hours: The meter uses the processor's internal clock to determine how long it has been running. Fixed point, HHH.MM. Parameter is saved on power down.> kWh: The meter uses real watts over load hours to accumulate kilowatthours. Floating point, KK.WWW to KKKKK. Parameter is saved on power down.** Press and hold the front panel button to reset kWh and load hours.Handily, the status indicator LEDs are red when in "standard" mode (V/A/W), and green when in kWh/hours/PF mode. As you become familiar with the meter, this indication will be easier to read - especially if the meter is partially obscured by a panel cover, or in a dark environment - than trying to make out the legend labels.Test Methodology:For testing, I placed the meter in series with my Hopi 9800 "kill-a-watt" digital power meter.Both meters were allowed to warm up for a little while. I took the pictures before this warmup, so it looks less accurate.The Hopi uses a digital KWH smart meter processor and a current shunt resistor that, while not calibrated, is known accurate within reason.The DIN rail meter is installed AFTER the Hopi.This is very slightly reducing the Hopi's accuracy.I did discover that the quality of the wiring to the meter matters greatly. Use at minimum 16awg for best accuracy.Test load is a desktop personal computer, booted to a steady state at BIOS.To test the clock, the meter's timer was reset on the second of a known time, and tracked using a quartz digital clock.To test the kWh, I reset both meters' kWh accumulators at the same time, and left the test load running for the duration of the clock test.The load posed by the DIN rail meter alone is below the Hopi's minimum, so to determine what its load is, I applied a light load (my PC "powered off") and then turned the DIN meter's fuse on and off to compare readings.While doing this, I went ahead and compared the readings of the light load between the two meters and found them acceptable. However, methodology was lacking to consider this test definitive.Speaking of methodology, as I was performing the final kWh and hour-meter testing, I realized that I could have improved my test accuracy further, however I didn't want to rebuild my test setup AGAIN, as it was getting late, and I was already 30 minutes into the rather long test.Just note that accuracy could be better than you see here.Accuracy Results:Voltage: 0.2v.Current: 0.02A.Wattage: 1W.Power Factor: 0.015.Time: Vs clock, 3 seconds in 1 hour; Vs Hopi, 3 seconds in 1 hourkWh: 1Wh in 1 hourMeter's power draw: At 121.7v, it draws 50mA, giving it 6.1VA, with a real power of approximately 300mW. This makes its calculated power factor 0.049 capacitive.

### ⭐⭐⭐⭐⭐ Use this for our Van
*by A***C on May 19, 2023*

The media could not be loaded. Very handy using this on our van to monitor usage. Very close to our inverter numbers, so when connecting to shore power or generator we have an idea how much amps we use. No complaints here!

### ⭐⭐⭐⭐ I got mine to work with modified sine by soldering two heat sinks to internal resistors to cool them
*by L***R on April 24, 2018*

Tell someone before they buy it that it does not work with modified sine wave inverters. I got mine to work with modified sine wave by soldering on two small heat sinks to two internal resistors to cool them down. I only draw 100 to 200 watts past it though
