Yes, I am certainly no photographer. To be honest, some of the marking on the sot23 packages are almost impossible to read regardless. You need the exact angle of lighting to read the markings, or a much better camera than my phone has.
The sot23 nearest to the inputs and connected to the 2 NAIS black relays are "LY" ,"EY", marked as Q1xx (FET's or BJT?), "A1" and "30Z" marked as Dx (diodes?). There are also sot23's on the underside.
All I have done at this stage is remove the big green varistor and it measures open or very high ? as does AG1 which is a "spark gap" or "gas tube" that also measures open/very high. I put 4.5V into the 2 NAIS relays and they do still appear to latch.
Just to recap, the meter is all but functional (ie boots, responnds to rs232 commands) except it does not display any readings on the large LED segment display and I do not hear the relays switching back and forth like normal ?. The front panel buttons work and I can switch between DCV , ACV, OHMS etc and the relevant units are illuminated etc.
