Operators Manual
After self-test, the control display shows the reset condition (below).
For a discussion of the softkey selection shown above (auto/locked), see "Auto Range
Versus Locked Range" later in this chapter.
Warming up the Calibrator
When you turn on the Calibrator, allow a warm-up period of at least 30 minutes for the
internal components to stabilize. This ensures that the calibrator meets or exceeds the
specifications listed in Chapter 1.
If you turn the Calibrator off after warm-up and then on again, allow a warm-up period of
at least twice 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, allow a warm-up period of
at least 20 minutes.
How to Use the Softkeys
The five keys just to the right of the P (Previous Menu) key are called softkeys.
Softkey key functions are based on the label that appears directly above the key in the
Control Display. Pressing a softkey either changes a value or causes a submenu with new
selections to appear on the Control Display. Softkey menus are arranged in varying
levels, as described in "Softkey Menu Tree" in Chapter 3. You can move backwards to
previous menu selections by repeatedly pressing P. Although pressing R will also
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 the P key as your main navigating tool
for moving around the menu levels.
How to Use the Setup Menu
Press the front panel S key for access to various operations and changeable
parameters. Most parameters are nonvolatile, meaning they will be saved during reset or
when power is turned off. Chapter 3 shows a map of the menu tree, lists the parameters,
and has a table of factory default settings.
When you press S from the power-up state, the display changes as follows:
