Scored a cool transistor checker I think

Snipped it just now.

These seem to sell for much more but pic does look pretty dusty and stated as untested. However the seller listed it as a Precision 530 rather then B&K precision 530 and I thinks that's why it went under the radar.

I found a free PDF manual on-line and it uses very conventional cmos digital ICs and analog op amps so any repairs should be easy as long as the meters are functional. I used one of these for a short time very long ago and it seemed to be a very comprehensive tester. You can can clip the three test leads to the transistor in any random manner and it will tell you if it's a NPN or PNP and what the pin assignments are, then you can proceed to further test gain, leakage, etc. A seperate section will test for Ft value.

Has anyone used one of these testers?

It got under my radar because he both skipped the B&K and also transistor.

he used semiconductor.....


I have a 501 curve tracer
a 510 portable battery operated checker
and a 520 line operated checker.

very nice for quick go/no-go checking and lead identification.

and the curve tracer is a bit too much at times.
 
I have a 530, a 520b and a 510 that has become less than reliable. The 530 is huge but it was the totl B&K transistor tester. I mostly use the 520b. It's quick and easy and doesn't take up half the bench.
