2.8 RATE Mode Operation
In RATE mode, the current count rate will be displayed.
If an alarm is not in progress, a long press of the ON/AUD button will reset the averaged rate
before releasing the button. The Reset feature must be enabled through Lumic 2.0 Calibra-
tion software and will be disabled when Sigma Audio is enabled.
A short press of the UNITS button will switch the displayed value between the Primary and
Secondary Units (also Tertiary Units if the detector is configured for alpha/beta).
A short press of the ON/AUD button will cycle through the “click” audio volume levels. When
Sigma Audio is enabled, a short press of the ON/AUD button will toggle the Sigma Audio
volume levels. If multi-level audio is disabled, a short press of the ON/AUD button will toggle
audio between Off and On.
If an alarm condition is present, a short press of the ON/AUD button will acknowledge and
turn off the continuous tone alarm audio. Under an alarm condition, the ALARM display
indicator will remain on as well as the alarm level icon. Alarms are non-latching in RATE
mode. When Sigma Audio is enabled, and an alarm condition is not present, a long press
of the ON/AUD button will reset the Sigma Audio alarm level. The Sigma count can only be
reset in RATE mode. If sigma audio and device rate reset are both enabled, the device rate
reset will automatically be disabled.
A short press of the LOG button, if datalogging is enabled, will log the currently displayed
rate.
