Brown & Sharpe 99-1033 digital indicator

Hi. Just received the B&S digital dial indicator that I won on EBAY. Didn't know much about it, but now I see it requires an AC power adapter/battery charger, which of course, were not included in the sale.

Looks like it uses a standard coaxial power plug. I have searched the WWW, but no mention of the specs of the power adapter. Can anyone help here?

It's also missing the tip of the plunger, but I can get or make one of those.

TIA

These were typically 5VDC with + in the center. If you don't have a variable power supply to experiment with, you might get one of the switch- configurable ones from Radio Shack and step it up until it works.

Thanks, Richard. I will try that when I get to the plant tomorrow.

Well, no luck with the power adapter. So, I disassembled the unit. Front half comes off easily after removing 3 microscopic screws! All looks ok until I finally spotted the battery. Has lots of gray hairs all over one end.

I let my general manager continue the disassembly, appropriately ESD protected, and he pulled a circuit board and the battery. A 4 cell NmH unit from Varta. It had only a single operating cell. The rest were dead short. A google search turned up the Battery Station with the replacement for $10.00. Should have a new battery by next year. Then we can move on to the next step to see if it still will work.

Will let you know the result.
