| Avo Megger BM80/2 beeping and shows E44 on display. |
| (1/1) |
| Paceguy:
I have an Avo megger model BM80/2 that when powered up beeps and shows E44 on the display no matter what position the function switch is in. I looked online to try to find the service manual with no luck. Help would be greatly appreciated. Thanks in advance. |

I have schematics for BM80-400 Mk2 - PM me. I have progressed some repair of my BM81/2, that also showed an E44. So far I had to replace an LM324 to recover a bad 2.5V reference line, and replace an LM339 to recover its nominal input node voltages, but BATTOK line is still pulled low when I think it should be nominally hi, so WIP but I last had this on the bench last year. Ciao, Tim |

Thanks Trobbins, I will check that out. |
