The new firmware also allows loop/continous testing.
So this might be useful for display testing. The higher levels are 
faster so the counting will not be visible any more.

>>> yes, the DL2416 is the same as the HP and I checked the tester works fine with that display.... well almost, for some reason the display needs to be installed upside down??.  fortunately it doesn't hurt the display to have power / gnd put onto pins 1&18 rather than 9&10
>>> a couple of suggestions on displays.... it would be handy if maybe the tester could repeat the display output until stopped, it is difficult to check each segment / dot so slowing down or speeding up the test would be useful.  since they are just a 'pass' anyway, just a continuous run through of the outputs would be useful.  On the HPLG-2416 especially ( as well as the DL2416 but to a lesser degree) doing the full illuminated all-on character would be useful.
