5.5 Alarm Menus
The NORTEC 600 instrument’s alarm options include BOX, SWEEP, SECTOR, or
POLAR. Up to three alarms may be used at any time. You can define the size, shape,
position, and polarity of each alarm. Owing to the number of alarm options, the alarm
definitions are grouped into submenus in the definition menu (DEFINE). There is a
submenu for each alarm that is enabled (ALARM 1, ALARM 2, and ALARM 3).
5.5.1 Alarm DEFINE Menu
The DEFINE menu is used to enable alarms and to set alarm polarity, the length of
time an alarm is active, and whether or not an alarm is audible. The DEFINE menu’s
available controls are ALARM 1, ALARM 2, ALARM 3, DWELL, and HORN (see
Figure 5-240 on page 293). Control functions for single frequency instruments
(NORTEC 600, 600C, and 600S models) are described below. Additional details for
alarms in dual frequency mode (NORTEC 600D) are detailed in “Dual Frequency
Menus” on page 109.
