Bq, Bq/cm², cps), a time-averaged exposure or dose (R/h, Sv/h,
Rem/h), or an integrated exposure or dose (R or Sv)
.
DOSE mode allows the user to view a real time integrated dose (R or
Sv) with the possibility of continually monitoring the integrated dose
during other modes of operation.
The standard handle includes three pushbuttons: the LOG button that
allows the instrument to log up to 1000 data points when activated with
the optional Lumic Datalogging Kit, an ACK/Reset button for
acknowledging alarms and resetting readings, and a PRG button for
entering setup mode and activating additional features.
The display will be automatically backlit if light levels are low or can be
set to a user-defined light level. The display backlight can also be
configured for “Continuous On” operation. RATE, MAX, COUNT,
and DOSE modes can be silent or utilize a “click” audio; the “click”
audio is always silent during COUNT mode by default. A "sigma" audio
mode can be enabled (disabling the "click" audio) in RATE and MAX
modes when scintillator detectors are used, and this mode makes it easy
for the user to find small increases above the background radiation
level. In this mode, the instrument measures background for 8 seconds
after power-up, and then beeps whenever the rate increases by a small
amount. Users are freed from watching the numeric value to "find"
something. They can simply listen for multiple beeps.
Setup of the instrument is accomplished through the front-panel
buttons, or through Lumic software available from Ludlum
Measurements.
Front-panel setup can be disabled via the internal switch on the Model
3003 in order to protect settings from inadvertent changes. When the
settings are protected, the user can view the settings or modify a limited
number of settings as defined with the Lumic software. Using the
Lumic software, the Model 3003 can be configured to allow changes to
the alarms and/or count time even when in protect mode.
The unit is operated with four alkaline AA batteries for operation from
-20 to 50 °C (-5 to 122 °F). Battery life is approximately 200 hours
under normal usage. A low-battery indicator on the LCD warns when
less than 16 hours of battery life remain.
The Model 3003 may optionally be provided with a 1/8-inch stereo
headphone jack that would allow for headphone use for audio output. It
is located to the left of the detector connector.
