CAL Menu and Passcode Entry

The CAL menu is accessed by pressing the

CAL

key in the default display

mode (see the Operations section for an introduction to keying data). The
CAL menu first requires that the user enter the 4-digit calibration
passcode recorded in the first page of this manual. Key in the calibration
passcode and press

ENTER

. Note that the passcode is not displayed during

entry, but asterisks (*) are displayed indicating entry of each digit as
illustrated below.

Note

All measurements continue when the CAL menu has been entered
(including the passcode entry screen). Selections of an option within
menus, such as the active calibration, are immediately valid and
will impact operation.

After the correct passcode is entered and the

ENTER

key is pressed, the

CAL menu tree will be available to the user. Each menu item is discussed
in the following paragraphs.

3.3.2

Sensor Input Selection

The sensor input selection menu allows the operator to choose the desired
sensor input for calibration. The selected sensor input then applies to all
subsequent menus in the calibration menu tree. The selected sensor input
will also be displayed in all subsequent calibration menus. Use the

OPTION

key to move the cursor. Use the

key to proceed to the next

menu.

3.3.3

Action for Selected Input

The action menu chooses between selection of a previously performed
calibration, or actually performing a calibration. At least one calibration
must be performed for the selected sensor input before the

Select

option

is available. Use the

OPTION

key to cycle between menu options. Use the

key to proceed to either the “select” or “perform” sub-menus.
