f. With output 1 set to 15 V, lower the voltage on the external power supply until the external (3458)
DMM reads −4.5 V.
g. Record the external (3458) DMM reading and the internal DVM reading. The difference should be
within the negative limits specified for the DVM in Table A-2.
h. Set output 1 to zero volts and repeat step g.
