Ebay IC Tester Instructions

The ubiquitous IC/Component tester found on Ebay usually comes without any instructions or documentation:

The unit I purchased came with a one page, 2-sided photocopy instruction sheet, so I thought I would share it here:

As far as I can tell, this unit will identify and test the following:

Common linear and logic IC’s
Some transistors; seems to be limited to bipolar
Zener Diodes

It does not appear to identify:

LED’s
JFET’s
Three terminal regulators

Thanks for reading,
