Just a quick question on the high and low limit LED operation. As I
read the schematic both U1B and U1D would light if the voltage to the
meter exceded the reference voltages set by the R11-R12 and R13-R14
voltage deviders as the measured signal is applied to the + (non
inverting) input of both comparators.

Am I right in assuming the connections on U1D should be reversed so
the LED lights when the measured signal is LESS THAN the reference??
