The PR-524 is the next generation in portable, hand-held photometry. It combines
illuminance and luminance measurement capabilities with cutting edge technology
by featuring a 1.5" x 2.3" back-lit touch screen display, USB interface, Secure
Digital (SD) card slot for measurement storage, multiple measuring head capability
and rechargeable Li battery. The only button on the PR-524 is the Measure button. |

Features
|
|
Back Lit / Touch Screen Display
|
|
All instrument set-up, measurement setup and file operations are performed via menus
on the touch screen display. The built-in back light makes it convenient for working
in dark ambient environments. |
|
USB Interface
|
|
The PR-524 can be controlled from a PC over the built-in USB interface. We've also
included an ASCII based Remote Mode control language and driver that emulates a
serial (COM:) port. For example, the PR-524 you can control using Windows HyperTerminal. |
|
Secure Digital Storage
|
|
Over 50,000 measurements can be stored on the 32 MByte Secure Digital (SD) card
supplied with the PR-524. |
|
Multiple Measuring Heads
|
|
If your application requires a multi-spot measurement such as projector uniformity,
the PR-524 can be fitted with up to 15 remote measuring heads - all under the control
of a PC communicating with the base unit over the USB interface. Each remote detector
is individually addressed. |
|
AutoSync® Source Rate Synchronization |
|
For the measurement of non-DC sources, the PR-524 will automatically determine the
source refresh or update rate and automatically adjust the PR-524 measurement parameters
insuring accurate and repeatable measurements.
|
|
Remote Trigger |
|
When it is necessary to either perform a hands off measurement or to measure a flashing
source such as a camera flash, the PR-524 can be triggered remotely, and once triggered,
will send a pulse to the remote source. Or, it can be used simply as remote trigger.
|
|
Luminance Measurements
|
|
For luminance measurements, the optional PR-522 SpotMate replaces the standard illuminance
accessory. The PR-522 features true Pritchard Optics for unambiguous target alignment
capability and can be provided with one of four measuring fields (apertures )- 2°,
1°, ½° or ¼°. For luminance measurements that are inaccessible
to line-of-sight measurements, an optional fiber probe accessory can be utilized
and for applications where it is necessary to make measurements of self emissive
devices in an environment where the ambient light cannot be extinguished, a contact
measurement Micro Reader Probe accessory can be employed. The PR-524 and the PR-522
can be ordered as a system, the PR-520 |
|
Remote Mode |
|
If you need to include the PR-524 into an ATE environment, we provide software that
creates a COM port when the PR-524 is connected to your PC using the USB interface.
Simply send a command string to the virtual COM port using ACII characters and the
PR-524 will perform the measurement and return the data requested in the command
string. This capability, unique among hand held portable photometers, gives you
complete control of the instrument and data returned from the measurement. |
