Verifying Voltages

Post by amb »

I have just assembled the kit version of this meter and am at the point of checking voltages.

Most are okay but I'm unsure about V- and VS-. I have:-
V- = -4.58V
VS- = -4.54V

Are these okay? The table doesn't have a minimum or typical value for these two voltages.

Edit: Having taken a look at the schematic I think V- and VS- should be pretty much negative versions of V+ and VS+ as they are generated by an ICL7660. As such I think my values are okay.
