Details:

On the model number id plate, I can defiantly make out T-101R/4v part but end is very faint. The unit comes with test leads and a compressor block. The scr gating test checks gate control characteristics and provide a means of matching scars according to their gate-current. This test is also monitored by a dc voltmeter and ammeter.

An easy-to-use instruction plate is included inside the front cover. This is for a, Cehco scr diode tester T-101R/4v, it comes as pictured in good overall condition. This test shows if the diode or scr will break down under operating conditions and is monitored by a peak reading dc voltmeter ammeter. It comes with everything pictured, if it is not pictured included.

The t101r/4v diode and scr tester puts the sophisticated testing capability of high-priced, specialized units into a portable package that is economically priced easy to use. It includes provisions for checking diodes and scars including axial leads, stud mount, flat packs opens, shorts, leaks, breakdowns under actual operating conditions. It looks like a 3 to me. I will picture the model id.
