i planning to make a voltmeter and ammeter for this power supply, i will step down the output voltage from the power supply and step up the voltage from the shunt resistor using two opamps configured as differential amplifier.
is the -1.3v from the power supply enough for the meter opamps?

i will use tle2141 for the meter.
