Q: Can it measure dc current with clamps? How low amps?
Preguntado por BG565338491 sobre 2021-10-15 09:53:21
rromano001 Low range has a full scale of 2A, instrument has 4 digit so it can display 1mA increment on both AC or DC measurement. AC is stable and measure current both AC (average value) or also average DC without sign detection. About precision and stability I report at almost is impossible to appreciate 1mA, zeroing instrument it has 2 3 mA dead band on short term. Measuring a small intensity like 10-20mA instrument is also non linear. Applied a measured DC current of 12mA DC: - on AC scale it measure 12mA stable regardless of current direction. - DC scale require zeroing instrument without current on clamp, just after zero display an offset of -2mA - immediate measure show values from 7 to 20 mA - reversing instrument the values are -10 -12 then continue changing. - In a few minutes offset raise from -2 to -12mA. IMHO on DC current not less than 50 mA can be measured without continous recalibration, may be you are more lucky and get a less noisy and lower drift one. Instrument is cheap and cannot ask them precision of expensive probes, I am very satisfied about performance

rromano001 Helloon September 2020 I left a request with same data your friend reported. not only theoretical max output but convertion rate prove is less than 21% as I argued for. 21% panel are double layer special. I suppose this is a stock low end performing less than 10% conversion of incident power.
Sykoma ihave one its about 20 watts max.

Preguntado por BG451516408 sobre 2021-07-31 03:14:42
rromano001 No laser included in this list. Controller has a port, motor support can hold it, so you can buy one.

rromano001 Aganlike the one I bough, they declare unreal IP grade. I don't see gasket nor protective shield so suspect this is no more than 41 42 and cannot be used outdoor. https://www.google.com/imgres?imgurl=https://atslab.com/wp-content/uploads/2018/09/ingress-protection-diagram-1.jpg

rromano001 Which model you bougth? Is your phone Full HD capable? App in general is poor but it display image at resolution of smartphone... when it work.

rromano001 No idea, I was unable to use. Put on recycle bin to do something in future or move to trash.

rromano001 Hello,I seen you pointed to AC only current. On text no DC current measurement is reported but at Base of Yaw on current appear the symbol of AC DC. I think one case is produced for cheap and DC. As you said good for price. Thank
Q: Hello, where can I get a user manual in Bulgarian?

Preguntado por jasonram1984 sobre 2021-02-13 12:59:06
rromano001 Hi, it is not specified but based on the one I received I see XL7005A as regulator, this is specified as step down regulator up to 80V with 85V absolute maximum rating. Capacitor is rated 100V 105°C, diodes are ss110 so 80V can be reasonable but IMHO 70V or less is more safe margin. Using a SEPIC module I decided for 24V input so not exercised @ top range.
