TG210 2MHz Function Generator

[tmcw]

Wasn't sure where was the most appropriate forum to post this, but since it's test equipment, I thought here...

Anyway, I got donated one of these boxes today, it's blowing fuses.

Anyone familiar with these instruments, and might be able to provide me with some starting points for testing?

Thanks.

EDIT: Also, does anyone know what the thing in the photo is called/used for? It was in a kit, and has thin bits of metal at both ends, which don't seem to be connected.

This is about the tool .
A picture of the TG210 2MHz Function Generator and who made it would be helpful.

Thanks for the link about the tool.

I've attached a photo of the front and inside of the instrument. Made by Thurlby Thandar Instruments. Voltage is selected (230V/115V) by flipping the fuse holder, and was set correctly for our 230V here.

From the power connector, I guess the fuse position directs the juice either through the red or orange wire. Blue comes from the on/off switch. Then from the other side of the windings to the board on the 3-wire connector. The 2 fuses there are still intact. With a good fuse in, power momentarily gets to the power LED, but the fuse blows pretty quick.

Disconnect the 3 wires that come from the secondary of the mains transformer (red-black-red) and see if the fuse burn again.

That way you can, or not, put the transformer out of the equation...

Re: TG210 2MHz Function Generator

Here is the manaual. Does it have the correct fuses(see pg-8)?

Re: TG210 2MHz Function Generator

Thanks, yes, both fuses were the correct rating (125mA), the connected one was blown, the spare blew when I swapped it in, I have no more fuses of that type. I'll get a box of new fuses, and see what happens when I disconnect the board from the transformer. If it doesn't blow the fuse, I guess the transformer should be good?

Make sure you get the time-lag fuses (T125mA).

Re: TG210 2MHz Function Generator

Ok, got the T125mA fuses, disconnected the 3-wire connector, and the fuse gets blown.

I guess this means the transformer is bad.

The label in the transformer reads as follows:

22115-0180/3/3
19.10.:5

The plastic moulding has some markings that can be seen highlighted in the composite photo of both sides. I also tried to highlight what I think is the manufacturers logo (CVP or CVD, maybe).

Anyone know how to interpret these numbers so I can get a replacement.
