2.2 WEARING THE TRACERCO PED
The TRACERCO PED is worn on the users upperbody.
Note that the calibration will be invalid if the TRACERCO PED is not worn
!
on the upper body. The TRACERCO PED must not be used as a handheld radiation monitor.
The clip may be used to fix the TRACERCO PED to the users belt or some other area of work clothes. The TRACERCO PED must be worn with the screen facing outwards. It is best to wear the TRACERCO PED on the outer layer of clothing for easy readings and to make sure alarm lights are visible.
The clip may be removed by simply pulling one side of the clip saddle away from the TRACERCO PED. The clip is reinstalled by pushing the clip saddle fixing points into the small cavities on either side of the rear of the TRACERCO PED.
To offer additional security a lanyard may be fixed to the clip hinge section.
2.3 START UP AND SHUT DOWN
To turn the TRACERCO PED on, press & hold the button for a few seconds until the status bar says 100%. During start up a screen showing the assigned user is displayed, assuming there are no alarms or warnings present. This screen is followed by a button operation message. The alarms are tested when the TRACERCO PED is starting up, so the device should flash and make a load beep sound.
The readings screen is automatically displayed after start up.
If the dose stored on the TRACERCO PED is higher than the dose alarm level the TRACERCO PED will bypass the start up screens to go straight to the readings screen and sound the alarm and beep.
The TRACERCO PED is turned off by entering the main menu and selecting the “switch off” option. See section 2.5 for menu navigation.

2.6 TRACERCO PED FUNCTIONS
2.6.1 Alarms
The TRACERCO PED has two adjustable alarm levels for both dose and dose rate. The alarm levels can be set using the DoseVision software.
The LEDs for dose and dose rate alarms will flash amber when the first alarm is reached and red for the second alarm. See section 2.1 for how the dose and dose rate alarm LEDs are positioned.
The TRACERCO PED will make a loud beeping noise for the audio alarm.
The dose rate alarms will continue until the dose rate drops below the alarm level. The dose alarm will continue until the total dose history has been transferred to the PC using DoseVision.
If the TRACERCO PED button is pressed during an alarm the audio alert will be silenced and the vibrate alert will stop. The relevant LED will continue to flash.
Dose and dose rate alarm levels are checked every second.
The TRACERCO PED alarm settings may be viewed in the alarm levels screen. See section 2.5 for navigation to this screen. The alarm settings may only be changed via the DoseVision software.
2.6.2 Tasks
A special function of the TRACERCO PED is the capability to allow users to monitor dose and peak dose rate over particular time periods or tasks. Tasks are started from the Task Menu screen. See section 2.5 for navigation to this screen. Tasks will continue to record, until stopped by the user.
8
Current tasks are highlighted by a green light. A trefoil/stop watch icon shows completed tasks. Current and completed task details may be viewed by selecting that task.
It is possible to record up to 9999 tasks on the TRACERCO PED. The four most recent tasks may be reviewed through the task details screen. Note;all task data logging periods may be displayed when data is viewed in DoseVision.
Task details may be cleared from the TRACERCO PED after data has been transferred to the PC using the DoseVision software.
2.6.3 Flip screen function
To aid the user in viewing readings during operations the TRACERCO PED has the special capability to flip the orientation of the screen. See section 2.5 for navigation to this function.
2.6.4 Screensaver
The TRACERCO PED screensaver is a blank screen. The screensaver can be switched off by pressing the TRACERCO PED button. The user may select the time period before screensaver activation. See section 2.5 for navigation to this screen.
9
TRACERCO recommend that the time period before screensaver activation should be kept
!
as low as practical. Long periods of screen activity will reduce the lifetime of the PED screen and deplete the battery more quickly.
2.6.5 Power status
The remaining battery capacity may be viewed in the power status screen. This screen also provides the user with an estimate of the run time left, both with the screensaver on or off. See section 2.5 for navigation to this screen.
The estimates run time are based on a battery monitoring algorithm and are therefore only approximate. The accuracy of the estimated run time also depends on the ambient temperature.
2.6.6 Monitor details
The monitor details screen shows various useful pieces of information about the TRACERCO PED and its status. Calibration contact details can also be found here. See section 2.5 for navigation to these screens.
10
2.6.7 Time zone
To make sure the dose history data is secure, it is not possible for the user to change the time and date stored on the TRACERCO PED. However, it is possible to change the displayed time to current local time through the time zone selection in the time zone screen.
The time zone screen displays the current time, date and time zone. See section 2.5 for navigation to this screen.
Note that the time and date stored on the TRACERCO PED can be set via the DoseVision software to the time (GMT) stored on the PC DoseVision is installed on.
2.6.8 Language selection
A unique feature of the TRACERCO PED is the capability to change the displayed text language. See section 2.5 for navigation to this function.
2.6.9 Activity Sounder
An activity sounder can be activated in this screen. Typical background radiation will produce approximately 12 counts per minute. The divide options allow the user to manage the ‘click’ event interval.
Selecting ÷ 1 means that a ‘click’ is generated every time a radioactive particle is detected. Selecting ÷ 30 will give a ‘click’ interval of about 2.5 minutes.
