6.7.1 Background Colors
The DRM-3000 provides a number of background colors on the display to help users
identify the radiological conditions and reasons for the audible alarms.
Each of the four display segments shows its own individual color, while the external LED
shows the color reflecting the worst case scenario as follows:
Green from background to first threshold
Yellow from first threshold to second threshold
Red from second threshold upwards or User Threshold (Alarm).
Blue Shows a Lost Contact condition between detector and Meter
6.7.2 Confirming an Alarm (TBD)
Clicking on any of the buttons on the Control Panel resets the Alert condition, silences the
buzzer and deactivates the solenoid. The background color remains either yellow or red as
long as the dose rate exceeds any of the thresholds.
The DRM-3000 provides both an audible and visible alarm when the following occurs:
Over threshold condition: There are two internal thresholds for dose rate. The background
color will change from green to yellow if the first dose rate threshold is breached and from
yellow to red if the second dose rate threshold is breached.
User Alarm threshold condition: This internal threshold is set via the RMVC software or
WebiSmarts Software and activates an audible alarm, changes the background color to red
and activates the internal solenoid: Clicking on any of the buttons confirms this alarm and
mutes the audible alarm.
