Hameg HM8012 ''OFF"
giannisv:
Hello all,
I have been using HM8012 for several years but suddenly the OFF indicator appeared on the screen. Is there any opinion on this problem?
F64098:
There seems to be a problem with the Cal-EEProm 93C46. Reject it and try to switch on.
Best regards
Frank

Dear Frank,
Fisrt of all thank you for answer but the eeprom 93c46 in a socket it's easy to removed and appeared on display CAL E (calibration error), the problem remains.
Best Regards,
Giannis

You can find the service manual here: https://sm5cbw.se/hameg/hm80/hm8012-serv.pdf
The display of 'OFF' is not mentioned in it and i never saw it on my 3 units.
So i have no further idea, what happened to your unit.
Best regards
Frank

Dear Frank,
You were absolutely right as soon as I replaced the eeprom 93c46 it works and you need calibration.
Thank you very much
Giannis
