Hey all, I have a load test of this type it and I wondered if I played my cards correctly with connections, I solder the two points for the''SSB''and place the meter on the resistance 1ohm. I measure voltage 1mV = 1mA Intencity or size?










Thank
 





Sorry... I don't understand your question...

If you are asking if the measured voltage drop across
a Test Load 1 Ohm resistor under load can me read as
1mV=1mA... then yes..

I weld the''Blu''for it is through the (-) for my driver with 2 ohm resistor I found a 530 mv multimeter to the means I have 530 ma ?

vous parlez français laserbee ?

flo.
 
Sorry.... I read and speak French but I do not write
French...


Jerry
 
shame because sometimes my translation is bad but if you read the french I could write twice
 
2Ω as the sense resistor should yield more like 625mA. Do you have enough supply voltage?
 

I find 530 mv to 2 ohms on a driver based LM337

this is normal?

According to the Rkcstr Test Load in your pic... there
is a 1 Ohm resistor on it [1R00]...

Not quite sure what you are measuring...:thinking:
I don't see a 2 Ohm resistor on the Test Load....:undecided:

I think he means 2ohm sense resistor on the driver, if your using an active current regulator like an op-amp CCR.
 
is exact, after the calculation of for my driver into 2 ohms and I will have no 625ma 430ma 530mv or when I pass the class ampere, the problem is that even with 4 ohms I have the same values: s my 7.2 v power supply

Good luck
 
Hey,
I tested with a groove which is limited to 500ma and I think 700 volts and amperage 400mA I find on my driver LM337 I put a 1 ohm, and I still have the same value with 2,3,4 ohms I know if I do it for the wrong test. help me plz

Thx
