What exactly is the procedure for adjusting the current consumption indicator? my meter overstates by 0.23A. when the potentiometer on the back adjusts to the appropriate value, then after disconnecting the current source, it does not show 0A, but just 0.23A. when the reset button is pressed, the measurement error starts to appear again.
What will happen to the power consumption if the current will flow in reverse? Thus it deduct from the previous consumption? Like if its used in a powerbank.
The meter that I have was intended to be used in a circuit requiring 50 100 amps however I want to use it for a circuit that is less than 10 amps I did notice that they didn't put a clamping resistor in the circuit that would be the resistor 00.05 my question is is without that resistor current will not pass that's an incomplete circuit if I use the shunt provided it is sizable I want to keep the installation small compact as possible
hello mate i just bought a keweisi 10a dc200 the keweisi cant turn on in my 4500 mah 7,4v 2 cell battery but in 100% the voltage can increase to 8,4v but dhe keweisi not turn on
if you reverse the current then zero current will be indicated reversing the big red and black wires will allow current to be measured you can add a dpdt switch with crossed connections to allow current to be measured without reversing the big red and black wires
I consider buying the *300V AC model* so it can be used on 230V Mains. I've found various models with same design concept... *KWS-AC300* 300V AC 10A shunt / 10A CT / 100A CT *KWS-AC301* like AC300 but also does Power Factor - also has Comms and more current *KWS-DC200* 200V DC 10A / 50A / 100A shunt *KWS-DC22* like DC200 but for electric vehicle? Similar front panels, but probably there is significant differences inside. Do you consider performing other reviews?
My 10A version can measure more than 10A . Today it showed 13,6A - charging current from FV pannel. The same value showed a PWM controller in serial connection. Have you tested max. value of current this measurement is able show correctly?
Hi sir!! I have an e scooter 72v 30a battery I connect the DC200 with the 100a version! All content as you say, before last picture! Connect all wires except the small black! The only thing i but more is a one-off switch! The measurement is Ok!! But after 2-3 minutes on off alone like it's overvolts and cut of power and give again!! I taught wires to understand overheating but No! Is any chance to make it from switch??? Either, did I make wrong to not conect the small black wire ( you in picture don't connect it) Thanks for the video my friend!!!🙏
Thanks for the video review. I just bought the larger meter that includes PF and frequency. My range says 85-250V not sure what the lowest will be since your version goes down to 8V. I wanted to use it to watch the output of a variable frequency drive at 220V, 60Hz, 1740rpm, 1hp, 3A, 3ph. Since the output is generated by PWM it may not work correctly. I will only connect to 1 phase. I'm not sure what to expect at say 10Hz speed and also the motor is rated for 120Hz inverter duty so 200% speed. Probably a good idea to try it out before I cut the hole in the front panel. I really like your electronic load. I'll have to look into one of those. Thanks again.
how to properly calibrate the current consumption indication? my meter is cheating. when the potentiometer on the back of the device sets the correct measurement values. then after disconnecting the load it does not show 0A. then i click the switch on the back and it resets. but after that the meter shows the current consumption again.
I have a 10A version meter. I also have a spare shunt from a 100A version. Can I safely use the 10A meter to measure high amperage with the help of the 100A shunt? Thank you.
this device has microcontroller and it is programmed to measure. The current is measured from the voltage drop of shun. Now if it received higher voltage first it might burn. if that does not happen, you will get 10 times higher reading and need to consider that.
Hi, I have explained all possible feature. except I couldn't find information as what was the job of the button at the time of recording and that is to press and reset the value.
Hello, If you live in Canada or USA, I am giving away this DL24P 180W load and energy meter. Make sure to sign up for it ruclips.net/video/-UblSfUEY-0/видео.html
I prefer these because I love their screens. Good to see you like the build quality as well. Thanks.
The button on backside is for resetting current to zero if it reports non-zero current reading even when there is no current through sense register.

What is the value of adjustable current resister.?current screw miss my module please value of screw?
When the current is reversed, does the cumulative aH/wH indication (on the bottom right side of the meter) deduct from the previous reading?
if you reverse the current then zero current will be indicated
reversing the big red and black wires will allow current to be measured
you can add a dpdt switch with crossed connections to allow current to be measured without reversing the big red and black wires
o modelo do meu é o ksw-dc200-10a mas a energia que sai dele, é metade da q entra, ja tentei de varias formas, oq pode ser? se entra 12v, sai 6v

If they manufacturer or reseller sends it for review, I will talk to them. WattHour.ca is our website

Hi, no image not. I simply respected the rating so the meter is not damaged.
The reset button is for correction voltage and amps that what they said on manual
Thank you.
The reset button is the menu key, I tried mine pressing for 3seconds and everything goes back to 0 except the voltage and temperature
Thank you.
Can it show the current direction
the button does work
if you press the button the meter will set whatever current is flowing to be indicated as zero on the display
thank you. I would have to test it and post the result in the resource page for this video.
It can b use as time relay or not ???

I wonder if a pair of these can be used with a dual polarity power supply. If this device will display negative voltages, it will work.
yes you can do that. each will word independently.
Dramatically fantastic. Greetings from Saudi Arabia. Thanks
Is it water proof ?
Of course not. That would have been huge advance and I would have mentioned it.
I love this keweisi, i have some of then. You can reset it on the front panel !
The reset button at the back is to reset the calibration modifications 👍👍
Muito obrigado pelas informações. 👏👏👏
Your title says "KSW" and I just bought the AC version and it says "KWS". I wondered if there is a typo.
Oh, thank you yes it was incorrect and I fixed it.
to reset measurments you need to hold the menu button 3 sec
Thank you for subtitles in Thai.
you are welcome. I am glad somebody acknowledges it
Hey mate! Is there a possibility to Set a Cut off voltage or to stop when a certain amount of Wh are reached?
Hi, I have explained all possible feature. except I couldn't find information as what was the job of the button at the time of recording and that is to press and reset the value.
you should collab with robojax. you both sounds familiar 😁
This is Robojax 😂and separated energy and power to this channel.
Can it measure power generation from solar panel?
My friend it just measure the voltage and current within the rage and does not mater where it comes from
Quite interesting!
Thanx a lot
Nice
Excellent video Thanks.
