D: Can it measure dc current with clamps? How low amps?

Domandata da BG565338491 il 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

D: include laser ? how much power

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

D: why isn't there an option for a 1080p drone in my phone?

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.

D: why after some time for example 15 mins go offline by itself??

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

D: Hello, where can I get a user manual in Bulgarian?

rromano001 It's almost impossible IMHO, you had to translate himself from English still has taste of original Chinese languages.

D: what is the max input voltage for the fan board

Domandata da jasonram1984 il 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.
