No. The A-119 has a AC coupled input. You have to short the capacitors C3
and C4 (the two large 100u types) to process DC signals with the input
amplifier.

Should be no problem after the C3/C4 mod. But I haven't tried it.

But we have the comparator module A-167 that can do this job without
modification.
