Warmup
Make sure the 5730A Calibrator is warmed up before use. The environmentally-
controlled components inside must be stable to meet or exceed the specifications in
Chapter 1. Sufficient warmup times are:
• If the Calibrator has been powered off for 1 hour or more, allow at least 30 minutes
of warmup time.
• If the Calibrator has been powered off for a length of time less than 1 hour, allow it to
warm up for at least twice the length of time it was turned off. For example, if it has
been powered off for 10 minutes, allow at least 20 minutes of warmup time.
Product Use
Touchscreen navigation is used to move throughout the 5730A Calibrator user interface
(UI) and menus.
