EPE resistivity logger

[Carl-NC]

Non not a single answer to max instead of 0A indication there are people here who had the same problem in the past i saw it in posts and i did not get a single answer .

They may not on the forum any longer, or not paying attention to this thread. If you see someone you want to ask in particular, try PMing them.

OK, thanks for the info. One day I hope to build this myself.

Carl dont hesitate to pm me for any problem on the epe logger.

Sorry for not answering in time.....Im very busy at the moment. I got your pm and wanted to answer as Im back from work. But now you found this modification from the second part of the everyday electronics magazine by yourself. .I had to go through some problems in building the epe logger by myself in the past...... Good to hear that you solved the problem...;-)

Problem of MAx in the display is the version hex of you used try other hex it will gone.

For those who are going to build this ERM logger in the future they and will face the same problem that i face on the display getting Max indication instead of getting the right one which is 0A you will have to perform the next modifications in order to fix it .

1. Cut the track between R16 And pin7 of IC4 (as it is mentioned in the part 2 on the epe magazine ) i am showing with an arrow in the picture .

2. Connect the now-open end of R16 to the pole of Switch S2
(in the picture i have place a red dot from where you are going to solder the wire )

3. After you do that and track is cutted R16 and S2 pole connected Turn on the erm press first and hold S6 (mode) and then while you are pressing and holding S6(mode) Press and hold also S8(Save) and the message (Ref saved will appear)
as you hold and press those two buttons release first S8 and then S6 .Then the value from Max will go to 0A .

Quote make sure the wires of the output are separeta and are not very very close .

This is the solution to AMAX value .
