Vetronix Tech 1A - Cartridges Required to Use

[chesnut]

Bought a 1992 ZR-1 last year.

So far, no problems, but want to be prepared.

Someone offered me a Vetronix Tech 1A to purchase.

Have some questions about cartridges:
- exactly what cartridges are required to trouble shoot anything?
- important things I need to know about the Tech 1A?

Thanks in advance.
