Weir 413D linear PSU: usage?
eti:
I've just bought this beautiful Weir (Farnell?) 0-30V (-15-0-+15) linear PSU, fully working and in beautiful condition. However, the button in/out combinations are a bit cryptic; does anyone know what this all means, and what the top two button do? (to the right of the meter) - thank you.
The image is the correct orientation here, but sideways on the forum; apologies.
Refrigerator:
The two combo switches on the top set the meter range, 30V or 10V, 2A or 6A range.
The switches below look like they just select transformer taps.
Here's the manual, i've haven't yet read through rather than just glanced at the schematic at the end of it.

Also i think this thread belongs in the test quipment section.

Thanks ever so much. Yes, I didn't put it in the "Test equipment" category, however, as I didn't think a PSU was a device which tests anything, in itself.
Neomys Sapiens:
I read it as follows:
The lower group of switches selects the actual power supply range, the upper switches select the range of the meter.
In itself, a strange unit.
Gyro:
Yes, Weir liked their multi output voltage range switching (I used to have a Weir Maxireg 761 with 15V/30V range switch). Just take extra care not to push the wrong range button with a circuit connected!
Good solid PSUs though, I never even changed a cap.
