Meter Update Frequency
The Meter Update Frequency settings control the regularity with which the meter is
updated.
While the instrument is in a Normal status condition, the meter will update at the
interval specified by the Normal setting. Units are in seconds. Default is 1 second.
Any Abnormal condition will cause meter updates to occur at the more frequent interval
specified by the Abnormal setting. Default is 1 second.
User Options
The Use password security option provides a method of disabling certain calibration
and configuration functions unless the user has entered an acceptable password. Two
password levels are supported: calibration and configuration. The calibration level
allows access to all menus and features, while the configuration level provides access
only to alarm settings and other non-calibration-related functions.
Default passwords are:
calib
for calibration, and
config
for configuration.
The Alarm Silence by menu only check box, when checked, required that alarms are
acknowledged from the Monitor – Acknowledge Alarm menu selection. When unchecked,
alarms may be silenced either from the menu, or by pressing the Alarm Ack button on
the face of the Model 334A. When paired with the Use Password Security option, the
user must have at least a config-level password in order to acknowledge and silence the
alarm. Default is unchecked .
The Disable buttons when logged out setting prevents the use of all three front panel
buttons by unauthorized users (not just Alarm Ack). It is only available when Use
Password Security is checked.
Default is unchecked .
The Skip Response Check on startup option allows startup and use of the unit
without performing a response check. When this setting is active, the Response Check is
only performed from a menu command. When unchecked, after a startup, the user is
prompted to perform a Response Check. Default is unchecked .
The Backlight incremental scroll bar controls the level of light provided to the LCD
screen. To achieve the 8-hr battery runtime, the unit should be set to the lowest setting.

the dialog from the menu by tapping
Monitor – Instrument Options… The dialog consists of at
least four tabs of settings and information: General, Logging, Isotope 1 and 2, Flow, and
