3-11. DC Volts Calibration (AUX Output)

To calibrate the auxiliary dc voltage function, use the same technique as previously
described for the normal dc voltage output, except use the AUX HI and LO terminals on
the UUT. Table 3-12 lists the calibration steps for AUX dc volts.

3-12. AC Volts Calibration (AUX Output)

To calibrate the auxiliary ac voltage function, use the same technique as previously
described for the normal ac voltage output, except use the AUX HI and LO terminals on
the UUT. Table 3-13 lists the calibration steps for AUX dc volts.
