Warm up the Calibrator
When you turn on the Calibrator, let it warm up for 30 minutes to let the internal
components become stable. Specifications given in Chapter 1 apply to a Calibrator that
has completed its warm-up procedure.
If you turn off the Calibrator after warm up and then on again, give it a warm-up period of
no less than two times the length of time it was turned off (maximum of 30 minutes). For
example, if the Calibrator is turned off for 10 minutes and then on again, give it a warm-up
period of no less than 20 minutes.
Use the Softkeys
The five keys to the right of

are called softkeys. Softkey functions come from the
name that shows directly above the key in the Control Display. Push a softkey to change
a value or cause a submenu with new selections to be shown on the Control Display.
Softkey menus are put in different levels, as given in the “Softkey Menu Tree” section in
Chapter 3. You can move back through the menu selections with

. Although

will return you to the top-level menu, it will also reset all volatile settings and return the
Calibrator to 0 V dc in the standby mode. Use

as your main navigation tool to move
through the menu levels.
Use the Setup Menu
Push the front-panel

key to access various operations and changeable parameters.
Most parameters are nonvolatile. This means they will be stored during reset or when you
turn off the power. Chapter 3 shows a map of the menu tree, the parameters, and has a
table of factory-default values.
When you push

from power-up, the display changes to:

This is the primary instrument setup menu. The list below tells you about the submenus
that available through each softkey and tells you where you can find more information in
the manuals.
