Tracerco PEDs
Tracerco’s Personal Electronic Dosimeters (PED2s) measure
and record both accumulated dose and dose rate. PEDs
measure the equivalent dose Hp(10), accumulated due to
gamma and X-ray radiation, which is the equivalent dose at
10 mm below surface of the upper body. Therefore, PEDs
must be worn on the upper body.
PEDscanbeconguredandmanagedusingTracerco’s
purpose built, cloud-based software, DoseVision2™,
referred to as DoseVision in this document. Data is then
automatically uploaded from the PED to DoseVision using a
Universal Serial Bus (USB) connection. DoseVision displays
data graphically and allows users to set alarm levels and
other settings on PEDs.
Attention: PED2 devices can only be used with
DoseVision2™ software.

PEDs measure dose rates in the range 0 to 100 mSv/h (0
to10 rem/h), with extended range calibration option for
all variants available to measure dose rates in the range
0 to 1.0 Sv/h (0 to 100 rem/h). The Tracerco PEDs are as
follows:
PED2
The PED2 is our standard personal dosimeter packed with
features as standard.
PED2-IS
The PED2-IS is an intrinsically safe version of the PED.
PED2+ and PED2-IS+
The PED2+ and PED2-IS+ range have additional features
such as:
• Built-in Global Positioning System (GPS) monitoring
for logging location information along with dose data
• Pop-up alarm messages which are customisable for
individual user scenarios
• Handheld mode, which allows both the PED2+ and
PED2-IS to be used as portable survey meters
measuring H*(10) dose rate

Warning - Risk of explosion
PED2-IS and PED-IS+ models must not be charged or have the battery cover removed in a
potentially explosive atmosphere.
Please read the Essential Safety Information document MN1021 for safety information.
Incorrect operation or maintenance may result in an explosion.
The equipment screen and case are conductive; however, it is advisable to limit the
possibility of static charge build-up by cleaning only with a damp lint-free cloth. Do not
exceedtheambienttemperaturerangestatedonthecerticationmarklabel.

MD1328-A PED2 User Manual

PEDs operate accurately for dose rates up to 100 mSv/h (10
rem/h), or 1 Sv/h (100 rem/h) for the extended range. The
accuracy of measured dose rates cannot be guaranteed above the
dose rate limit. Therefore, there is the potential for inaccuracies
in subsequent accumulated dose values from the time of overload
until the data has been cleared and a new accumulation started.
Attention: The actual measured dose rate values are still
recorded and readable when transferred to DoseVision.
Alarms alert to dose rate overload as follows:
• Onthehomepage,thedoseratewillashredandaDetector

• Alarm sounds continuously until the button is pressed
Oncethedoseratefallsbelowthemaximumspeciedrange,
the top of the screen returns to the standard display and the dose

Setting up the PEDs
Before using your PED, set the alarm levels, logging
options, units and, if required, manage users using the
DoseVision software.
Start up and shutdown
To start the PED, press and hold the PED button for a few
seconds.
During startup, the screen shows the assigned user,
assuming there are no alarms or warnings present,
followed by a button operation message. The alarms are
tested when the PED is starting up, so the PED should

screen is displayed after startup.
Attention: If the PED is not set to zero dose on startup, and
if the dose stored on the PED is higher than the dose alarm
level, the PED bypasses the startup screens to show the
