5.5. RATE MODE

25

Both the alert and the alarm are automatically re-armed when the readings fall below their
respective thresholds.

OK button: When a new alert and/or alarm is tripped, a press of the OK but-
ton will acknowledge the alert and/or alarm to silence the audio instead of the
normal mode specific function.

• An ALERT will flash the orange LED and sound a tone. An alert can be silenced.

• An ALARM will flash the red LED, sound a tone, and flash the ALARM icon. An alarm

can be silenced.

• A FORCED ALARM will activate when the reading exceeds the user configured maxi-

mum display. A forced alarm is similar to an ALARM with the addition of the maximum
value or 888 flashing on the display. A FORCED ALARM CANNOT be silenced.

Figure 5.1: Alert example in rate mode.

Figure 5.2: Alarm example in rate mode.

5.5 RATE Mode

In RATE mode, the current count rate is displayed. The rate is averaged based on the re-
sponse rate setting.

OK button:

Toggles click audio (or other activity indicating audio). If there

are alerts/alarms, the alert/alarm acknowledgement takes precedent and will
register the button press instead (see Alerts and Alarms on page 24).
