Documentation, for Stabilock 4013, anyone?

[OZ4ACL]

Hi!

Have been using a few hours, trying to get Service manual or similar for the Stabilock 4013.
Unfortunately with no luck.

The closest, is a Servicemanual for the 4010, 4011, 4020 and 4022.

But there's a few differences between these, and the 4013. It seems the 4013 is a modified 4011.
Maybe mostly converted to dB/µV? This as the front type number, is a sticker atop the 4011 number.

Anyone know more?

Best regards
Tonni
