Sacramento, Ca My Country: Any idea why it’s not calibrating? Originally Posted by stj no, it’s a kit from ebay with a red pcb. It is not a 10ppm. Find More Posts by socketa.

And it was working fine.

But i can not find the chip at Conrad Elektronics. ESR meter upgrades that’s the part, i’ll take a foto later of how to fit it – because it’s not the same as the lm it replaces. Maybe someone here can take a look. The Programmer has arrived. All times vatasheet GMT Last edited by socketa; at If i did not miss anything. Originally Posted by stj which kit are you waiting for?

So, is this calibrated, or not?

The time now is Thanks that would be nice! ESR meter upgrades the test routines have been changed a few times over the past year.

Can someone check if i have found the right PMIC https: Page 35 of Dam the ebay seller is not shipping to Germany. It then visually flashes the capacitance measurement on the LCD for two or three minutes. And can you also help with the other chip. ESR meter upgrades Yeah, Strapped terminals 1, 2, and 3, and removed them when said to isolate. A friend works nearbuy this shop and can get it for me.

ESR meter upgrades use this programmer link http: Nuneaton Warwickshire My Country: Then i select “turn off” With no components inserted, i turn it back on It tests the battery correctly Then displays: ESR meter upgrades i recommend this at the moment. I think it was a 5V low dropout voltage regulator. West Sussex My Country: ESR meter upgrades The Programmer has arrived. So i do not have to pay for shipping.

Data Sheet Catalog: Begin marking SMD with 5

If i insert a capacitor, and push the button before it displays the “not calibrated! Then i test a few caps and it gives good readings.

ESR meter upgrades the actuually looks pretty impressive! Yes it is this one http: And i do not have the knowledge to check for a chip with similar characteristics. But maybe they have something similar that i can use. Then it asks for nf, so i give it 12nf It then displays the capacitance briefly. Find More Posts by stj.

Yeah, Strapped terminals 1, 2, and 3, and removed them when said to isolate. ESR meter upgrades Thanks that would be nice! But i thought that it tested voltages; so bricked the chip. ESR meter upgrades Thanks bud That fixed it. And then it displays “Test end” And then returns to the menu.
