Title: Knick JS3010 Documentation needed
Post by: Aheld on November 05, 2024, 06:48:15 pm

Hi Forum,
I have a Knick JS3010 DC calibrator which is slightly out of spec. I didn't find any variable resistor etc. for fixing.
So I'm wondering how to calibrate this device? (Equipment for calibrating this device is available)

Badly, I have no documentation for this device.

Is there any body who can help me?

Thanks
Axel

Does anybody know the calibration unlock code of the JS3010?

Probably Knick can provide them.
Some years ago while doing some EPROM Backup etc of my Knick Stuff (J152 S252 JS3010) and repair of a J152 I was curious about the Z80 system. I needed to do a calibration so I tried to find the "PASSZAHL" myself. There is actually a second passcode which grants some sort of full access. But I'm not sure anymore what you could do with that.

It looks that the passcode is the same for all of the models from this series J152 S252 ans JS3010

I don't want to share it publicly, but can provide them via PM.
