[Amps] AL80B power meter not working

[Steve Thompson]

A minor point, not really relevant to your test - 1N914 is a 
'regular' diode like 1N4148 except that 1N4148 has lower leakage.

I mention it only to avoid disappointment should someone grab a 
1N914 for a situation where a shottky is essential.
