INTRODUCTION

Thank you for purchasing General Tools & Instruments’ HHUV254SD UVA and UVC Light
Meter

with Datalogging SD Card. Please read this user’s manual carefully and thoroughly

before

using the instrument.

Many industrial and commercial applications require or can benefit from measurement of
the intensity of UVA and/or UVC light. Among them are welding (to minimize exposure to
“blue light” radiation), UV
electri

cally programmable read-only memory (EPROM) chips, production of graphic arts

products, exposure of photoresists, and curing of inks, adhesives and coatings.
The HHUV254SD has the performance and features needed to satisfy the most demanding

aspects of these applications. For example, it combines the capabilities of UVA (black light
in the long-wa
in on

e instrument. The meter also can measure surface temperature, if mated with a Type K

ve 365-nm band) and UVC (short waves in the 254-nm band) measurement

or Type J thermocouple. A UVA probe and a UVC probe are supplied with the instrument.
Because it is microprocessor-based, the HHUV254SD can make full use of the portability,

reliability and large storage capacities that SD memory cards offer. Measuremen
inten

sity or temperature can be made automatically at any of 11 sampling rates between
one second and one hour. After time-stamping and storing the measurements on an SD
card plugged into the instrument (a process called datalogging), the user can remove the
card and transfer the measurements to a laptop or desktop computer either directly or via a
USB card reader.

The HHUV254SD has a backlit 2-1/2

MAINTENANCE & TROUBLESHOOTING TIPS

Keep the UV light probes clean and their sensors under their protective covers when not in use.

When the icon appears in the left corner of the display, it’s time to replace the six
“AA” batteries that power the instrument (although measurements will remain valid for
several hours after the low-battery indicator first appears). Replacing the batteries requires
removing the two screws that hold the battery compartment cover in place, as explained in
Step 1of the setup procedure on page 5. After inserting fresh batteries in the correct
orientation, tighten the screws to secure the cover.

10

If the meter “freezes” (like a computer) and buttons become unresponsive, try resetting the
instrument by pushing the RESET button on its right side (callout 1-11 of Fig. 1) with the
end of a paper clip.

Remove the batteries when storing this product for an extended period of time.
Do not drop or disassemble the instrument or immerse it in water.
