ESR-micro v 4.0 (снят с производства) / Re: problem after a measure of a capacitor charge!!

« : 14 Июнь 2012, 22:02:49 »

sorry i didn't know there were holidays in Russia! :-)

ok..i will insert 10ohm resistor into socket and tune R15 ,but before to insert the resistor i have to do always the calibration with a wire or not?

here the read of capacitance:


1000uf 16v

with multimeter: 992uf  with esr meter (right soket): 1007uf  with esr meter  (probes): 975uf

470uf  16v

with multimeter: 425uf  with esr meter (right soket): 420uf with esr meter  (probes): 406uf

330uf  25v

with multimeter: 321uf  with esr meter (right soket): 318uf   with esr meter  (probes): 307uf

220uf 35v

with multimeter: 202 uf  with esr meter (right soket) : 198 uf  with esr meter (probes): 192uf

3.3uf 450v

with multimeter: 3.61 uf  with esr meter (right soket) : 3.83 uf    with esr meter (probes): 3.83uf

4.7uf 350v

with multimeter: 4.98 uf  with esr meter (right soket) : 5.30 uf    with esr meter (probes): 5.28uf

2.2uf 100v

with multimeter: 2.02 uf  with esr meter  (right soket) : 2.18 uf    with esr meter (probes): 2.18uf

i done these measure with right soket and with the probes the measure are different for the high capacitance!

i noted that the calibration of probes are wrong!!

if i put the probes in the left soket after the calibration i read:

1 ohm: 1.15
10 ohm: 11.7
100 ohm: 125



i repeat..until i broken the esr meter the read of capacitance between multimeter and esr meter were similar!
now i see some difference and i don't know if the esr is affidable!

after when i will come back at home i will tell you the capacitance.


thx always for your excellent support!!

please help me!   

now i am not using the esr meter because it's not affidable!

thx for the manual!
i sent you the english version ;-)

but i have some problems again!!!!

the capacitance is wrong!!!

i will explain how i tune it!

with esr meter switched off i put a wire in the right soket,switched on and waited for calibration;after i put a capacitor of 470uf and i tuned R9 until i read the correct capacitance.
i pulled out the capacitor and switched off the esr meter.
after i put again the wire in the right soket with esr meter switched off,after i switched on the esr meter and waited for calibration;after i put a capacitor of 1000uf and i tuned R9 until i read the correct capacitance.
i pulled out the capacitor and switched off the esr meter.
after i put again the wire in the right soket with esr meter switched off,after i switched on the esr meter and waited for calibration, i put again the capacitor of 470uf but the read was wrong!!! it strange..it seems that when i put a capacitor and tune R9 and after i put another capacitor and tune again R9 seems i lost the tune i did before for the other capacitor..then the capacitance is never correct!
did you understand?
is it possible the diodes of protection are broken or not or other components for the read of the capacitance?

P.S  if i do the calibration with the probes on the left side and after i read with the probes on the left side 1-10-100 ohm, i read 1.25 ohm - 12.5 ohm - 112 ohm !!!

no i received only the esr micro without the manual at my home!

can you send me this russian manual in email with all these explanation?

ok thx!! 
can you tell me where i can find the picture you told me?
i didn't find on the russian manual!

yes it's true!   

sorry for my incompetence!!   

then i have to use a wire to do the jumper on the soket!
then first i tune the capacitance and after the esr,always with the wire! 

thx for all!
today i will do the tune!

thx for the manual. but is it the same i find on the site in pdf?

i have bought a normal resistor of 1 ohm to change the broken resistor and soldered in the esr meter: i read it with multimeter and it's of 1.14 ohm. is it good or not good for precision?

after i did all the tune but i don't have the correct values..i explain you what i have done:

with esr meter switched off:

i put the capacitor of 470uf in the right side soket,i switched on the esr meter and i waited for calibration done and after i tuned the R9 until i read the correct capacitance and after i switched off the esr meter.
after i put another the capacitor of 1000uf in the right side soket,i switched on the esr meter and i waited for calibration done and after i tuned the R9 until i read the correct capacitance and after i switched off the esr meter.
i put again the capacitor i calibrated before of 470uf and the measure now is not correct.

after i tried to tune the esr:


with esr meter switched off:
i put a resistor of 10 ohm in the right side of the soket, i switched on the esr meter and on the display i read 10 ohm.
after i switched off the esr meter and i put a resistor of 0.22 ohm in the right side of the soket, i switched on the esr meter and waited for calibration and i read a wrong value of resistance,then i tune the R15 until i read the correct value.
i switched off the esr meter and i put a resistor of 0.33 ohm,i switched on the esr meter,waited for calibration and i read a wrong value of resistance,then i tune the R15 until i read the correct value (about 0.33).
after i switched off the esr meter i tried to put again the resistor of 0.22ohm,switched on the esr meter,waited for calibration and now the value was again wrong and not 0.22 ohm.

it seems the values not are registered in the esr meter when i go to tune the r9 or r15 for othe measure.

i have to check other components?

YOU NEED TO INSERT RESISTOR INTO RIGHT SIDE OF SOCKET (INSTEAD OF CAPS) NOT LEFT!

now i read!

i have to do the calibration with the resistor on the right side of the soket to tune capacitance and esr and not in the left side of the  soket.
is it correct?

then the left side of the soket..what's his use?

ok thx :-)

then i need of some low resistors for example 0.22 ohm 0.33ohm 0.50 ohm and 1 ohm.
tomorrow i will buy it!  if i will find it!!  lol  ;-)

but if i try to do the calibration with the lead in the left soket where i read "1 ohm" and i read on display 1 ohm, i don't need to tune R15!
is it correct or not?

« : 03 Июнь 2012, 22:56:20 »

perfect!!
now i have understood!  lol

then i need of a resistence of 10 ohm to put into left soket where there is wrote "10 ohm" and after i tune the R15 until i read 10 ohm.
do you think i have to tune also with a resistance of 100 ohm in the left soket where i read "100 ohm"?
then i need also of a resistance of 0.22  0.33 etc etc.. and 1 ohm to put always in the left soket where i read "1 ohm" and after tune by R15.
is it correct?

thx for your great support!

ok thx a lot!
sorry for my poor english..in your last post you tell me to put a resistence of 1 ohm with max 5%of tollerance and after i have to put a capacitor in the right socket of esr meter and then tune the left potenziometer until i read the correct value of the capacitance..is it correct?
left potenziometer is R9?
and the right potenziometer R15 what's his use?

« : 03 Июнь 2012, 12:33:48 »

can you tell me the tollerance for the resistance?
because that i have put is a smd resistance of 1 ohm but if i read the value with multimeter i read about 1.20 ohm.

thx
