Re: 497p front panel cal failure (CF and Ref Lvl)


Well, it did it once, then repeated attempts failed. Would bad power supply bypass caps on the PC boards cause problems? I have a few caps that are open or high ESR, all are decoupling caps on the power supply rails on various boards. Parts on order, but won't be here until next week from Mouser. Power supply voltages are good, and I don't see appreciable noise or ripple.
