1. INTRODUCTION
1.1 GENERAL
The AccuMAX™ XRP-3000A advanced digital
radiometer/ photometer features a microprocessor-
controlled readout unit with a dual-sensor detector to
accurately measure both ultraviolet and visible light. It
is specially engineered for nondestructive testing
(NDT) applications. The UV-A/VIS sensor connects
directly to the readout unit or via a USB cable with a
water-resistant sensor adapter. A visible luminance
sensor is available as an optional accessory.
The XRP-3000A provides black light (long wave UV)
readings from 0-100 mW/cm
2
, and visible light
readings from 0-5,300 lux, (0-500 fc). See Table 2-2 for
specifications. The XRP-3000A has an overall
accuracy of better than ±5% with reference to NIST
standards and conforms to black light and visible light
MIL and ASTM specs for FPI and MPI in NDT
applications.
The sensors are loaded with low electrical impedance,
making their linearity vastly superior to that of any
other comparably priced radiometers. The sensors
are provided with a special diffuser-sensor window that
helps prevent filter degradation and ensures accurate
lambertian or cosine response.
The XR-1000 readout unit has a maximum 4-digit
autoranging, monochrome LCD display and is protected
by a rugged rubber boot. Additional features of the
electronics include excellent temperature coefficient and
over-ranging characteristics and built-in autozeroing.
1.2 FEATURES
The XRP-3000A is compact, lightweight and battery-
operated for convenient use in the factory, field or any
other location where measurements need to be taken.
A slide-out panel allows easy replacement of the unit's
9-volt batteries.
•
Menu-driven functions provide multifaceted light-
level readings.
•
Functional features embedded within operational
modes further clarify the type of data desired.
•
SETTINGS buttons provide user-selectable display
parameters at any operational level.
•
Intuitive screen prompts provide main operational
functions (normal, autozeroing and integration).
•
BACK button repeats information from previous
screen.
•
Microprocessor-controlled readout unit with dual-
wavelength sensor detector.
•
Superior band-pass interference filter.
•
Choice of direct connection or USB cable with
water-resistant adapter between sensor detector
and readout unit. Standard, commercially available
USB cables can also be used.
•
Excellent cosine response.
•
Automatic shutoff.
•
Large, easy to read LCD screen.
•
Sealed sensor housing.
•
Press and hold ON/OFF button prevents accidental
shutoff.
1.3 PRECAUTIONS
•
This radiometer is carefully designed to prevent
accidental shock to the operator when used properly.
However, no engineering design can render safe an
instrument that is used carelessly. Therefore,
recommendations presented in this manual must be
read carefully and thoroughly understood before any
measurements are made.
Failure to follow
directions could result in serious adverse effects.
•
The UV-A sensor is designed for use in regions of
the spectrum, notably the ultraviolet range, which
may be hazardous to the eyes and/or skin of
individuals. Ultraviolet protective eyewear and
facewear are available from Spectro-UV for instances
when UV exposure is unavoidable.
•
Do not leave the exposed sensor head under the
light source any longer than necessary to take
measurements. Prolonged exposure can result in pre-
mature aging of the sensor, necessitating more fre-
quent recalibration to maintain accurate readings.
•
See Section 10, Warranty, Maintenance and Battery
Replacement, for more information.
