Default Test load l

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 find 530 mv to 2 ohms on a driver based LM337

this is normal?

2Ω as the sense resistor should yield more like 625mA. Do you have enough supply voltage?

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...
I don't see a 2 Ohm resistor on the Test Load....

I think he means 2ohm sense resistor on the driver, if your using an active current regulator like an op-amp CCR.

Default Re: Test load l

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
