- Hard to believe I know but in my last video I made a mistake. Thanks to my wonderful viewers however not only have I seen my mistake, I've learned from it!

Adam you are class act. Well done.
I am looking at getting one of those clamp meters. It will come in handy with my small solar set up. All the best Mike bkk
+Bangkok Homes You're too kind. Thank you.
Adam, a rather lovely response and beautifully explained. I like your teaching style. Keep on exploring I'm enjoying the journey
👍
+Dean Greenhough Many thanks Dean.
MrJohhnny isvery observant and resourceful person in this small electronics vlog viewers community.
Thank you for the vid - I almost bought AC current clamp meter to measure my car current usage - where in cars there is DC current ;) Perfect explanation
I missed that! A lot of folks don't "zero" when taking DC amperage readings too. However, you smartly did that! Great review.
Indeed, that's very important. It's also a good idea to perform the zeroing with the meter in a position close to (but obviously not already clamped on!) the conductor you are going to measure.
xanataph bro can u tell me that how does hi just switch Dc to Ac in same current? Without change the wire?
800mA ripple at what frequency? If it's too 50/60Hz that's fine, but if it's got high frequency components you might have EMI issues and need to put a filter on the inverter input.
Everybody makes mistakes, you learn much more from them than you do from a successful experiment. By the way, that waveform looks nothing like I thought it will :) Did you measure the frequency of that ripple? It may be 100 or 200Hz, not a 50Hz you would expect. Just curious
A low pass filter on a Hall effect clamp meter will filter out the AC ripple, giving you a better DC current reading.
we learn from mistake. good job!!
where can i fined this little oscilloscope?
I learned something today , does the meter has Max , Min memory?
+Hobbyandtech Nope. This one doesn't I'm afraid.
Would be to good to be true still looks really good and compact
Hi / Is this device very accurate or not accurate inAccurate or not measurements/Please reply and clarify
Where did you get the little yellow oscilloscope?
is it normal when i put it on dc amp my meter already show 0.5 amps on the display ?? is that normal ??
Bro plz can tell me in which cases the meter can be damage?? Like wrong selection of rotary switch? Does in such cases meter can be damaged if select the dial at diode registance and frequancy and measure the voltage and amps?
Hall sensors and opamps are attached to the clamp and the amplification is switched over.
More than 100 amps could be dangerous, and not just for the meter.
On the other hand are PTC and resistors. Voltages over 600 volts are dangerous.
For such high currents and voltages, however, I would not use the small meter with thin measuring cables.
The device is not suitable for voltages in household electricity or industry high voltage.
For the hobby sector, 60 amps and less than 250 volts are a lot for such a small meter.
Amigo. Hola
Cuanto vale ?
I've done exactly the same thing! bit embarrassing
