how to test a quadrac out of circuit?

[Bill Sanderlin]

I have a 6015LT-ND quadrac that I would like to test out of circuit. Is
this possible and how would I do it with a simple DVM?

Thanks,
Bill

How thoroughly do you want to test it?

You would need the spec's on the unit.

in short, you have M1, M2 and T legs.

I don't know what your devices pin configuration is
how ever, I'll guess it to be M1,M2 and T as in 1,2,4
reading left to right while looking at the front side
of the package.
M1,M2 should not read anything on your DVM in diode
mode either way. It should be in the infinite reading of
your meter.

T (trigger) should also not read anything related to any
of the M1,M2 legs. That leg requires a minimum level of
voltage before the internal diac breaks over to bias the
TRIAC.

If you're getting any form of low reading with any combination
of this device, I consider it to be defective.

It might be best to actually test this in circuit using a
Volt meter..

The T leg should have around 30..50 volts AC before it can
trigger. The M1/M2 should have AC constantly there at all times.
The remaining M1/M2 will be on the load side..
