calibrator/amplifier must all be powered up for a minimum of one hour before calibration
 The Agilent 3458A “Auto Cal All” procedure must be performed prior to calibration.
 The 5700A’s “Cal Zero” procedure must be performed prior to calibration.
 Ensure that the “I FUSE” is installed in the EX1200 DMM.
