3-4. Starting Calibration
From the front panel, you start calibration by pressing the S key, followed by the
CAL softkey twice, then 5500A CAL. The CALIBRATION SWITCH on the 5500A rear
panel can be in either position when you begin calibration. It must be set for ENABLE to
store the correction factors into nonvolatile memory.
3-5. How the Calibration Procedure Works
The calibration procedure is self-prompting, with a chance to ABORT and DISCARD
any changes after each function is calibrated. After you press the 5500A CAL softkey,
the procedure works as follows:
1. The 5500A automatically programs the outputs listed in the following tables and
prompts you to make external connections to appropriate measurement instruments.
2. The 5500A then goes into Operate, or asks you to place it into Operate.
