The SPR-365 is a Longwave Ultraviolet (UV A) LED Flash Light (Torch) designed for
Magnetic Particle Inspection. The unit should be used within the parameters as set out in the
specifications outlined in this Manual.
1. Push Button Switch – The Push Button Switch was designed for comfort and safety, but
should only be considered water resistant. Push the button once and the lamp turns on,
pushed a second time and the lamp turns off.
If the lamp fails to turn on, the Battery may be installed backwards, so try turning the battery
end for end. If that fails, try the spare battery included in the kit. If the second battery fails to
turn on the lamp, charge the battery for about 10 minutes, then try the light again. If again the
lamp fails to turn on, repeat the procedure with the first battery. If this fails to work
either the switch or LED are damaged and must be returned to an authorized repair depot.
For short periods of time, the SPR-365 can be operated from the charger.
2. Battery Replacement – The Battery is Charged Externally in the supplied charger
Housing. The Lithium Ion Battery is charged with either the 115/230 VAC Charger or the
12 VDC adaptor. Attention must be paid to the Positive End and Negative Ends of the Battery,
where standard conventions are agreed by making the Positive End a button (or small

diameter) and the Negative End flat (larger diameter). There is a legend inside the Charger
Housing, which shows the positive end out. If the battery is positioned wrong, the charger will
not start.
3. Reflector Replacement - The SPR-365 is supplied with 2 Reflectors, to permit Focusing
or Defusing the light. The Focusing Lens in smooth inside, while the Defusing Lens is
pebbled. The Reflectors are changed by carefully removing the Lens Bezel, being careful to
prevent the lens from dropping. The existing Reflector is then simply remove the other
Reflector is installed. Operators should try both reflectors for particular inspections that may
iffer from background light, part geometry, etc.d
4. Operational Parameters –The SPR-365 is intended to be turned On and Off very
regularly to save on battery life. To be more specific, do not leave the unit turned on when it
is put aside. The operator should get in the habit of turning it on when inspecting the
workpiece, and off when not. This practice will prolong the charge in the battery, so a fully
charge battery can last a half day of inspection, and the spare for the balance of the day.
The SPR-365 can be left on for prolonged periods of time (45 minutes), but the Lens
Housing should be felt to ensure it does not get excessively hot. High power LED’s do not
tolerate heat well, so turning the unit on when in use, and off when not, will ensure a long
service life of the LED Assembly (LED, Printed Circuit Board and Heat Sink).
Over time, the Lens/Filter may become clouded do to the intense UV light. When Clouded
the Operator may notice a reduction in UV Irradiance, but this will become evident with
checking the unit with a Longwave UV Radiometer. Replacement Lens can be ordered
separately, but are not considered a consumable item.
5. Field Characteristics – The SPR-365 produces an intense UV illumination area of
approximately 5” (or 120 mm) at a distance of 15” (38cm). The average intensity over this

area is 5,000 цW/cm², however the area just outside the center of this area will be higher
than 10,000 цW/cm².
6. Maintenance – After extended use the SPR-365 should be cleaned with a mild soap
solution and thoroughly dried. The unit should be visually inspected for any damage that
could cause harm to the operator, or the material being inspected. Special attention should
be paid to the Push Button Switch Cover, to ensure its fit is acceptable and it is not cracked
or failing in any way.. The most important item is to ensure Oil is not allowed to soak into the
rubber switch cover, which will cause it to harden and crack.
Whether industrial specifications are being observed or not, the LED Flash Light should
be tested periodically, using a calibrated Longwave UV Radiometer to ensure it continues
to have a minimum output of 1,500 цW/cm² at 15” (38cm). If the unit fails such a test, first
inspect the Lens to ensure it is not clouded or dirty. If the unit continues to fail, contact
the Distributor or Western Instruments for instructions on corrective action.
7. Battery Charging – To charge a SPR-365’s Lithium Ion Battery, it must be
installed in the Charger Housing, with the End Cap securely tightened to the Body. First
Plug in the charger’s voltage adaptor (115/230 VAC or 12VDC) to the electrical power
source. When the 12VDC Adaptor is plugged into an Accessory Outlet the LED will be
Red and will remain Red after charging. When the 115/230 VAC Adaptor is plugged into
mains power, the LED will be green, and when it is plugged into the Charger Housing the
LED will change to Red.
The 3.7 Volt / 2600 mAmp-Lithium Ion Battery will take approximately 6 hours to fully
charge. The batteries can be charged at any point of their cycle, but should
not be left on the charger for more than 12 hours at a time. It is recommended the
operator start his day, or an inspection cycle, with both batteries charged., which will take
a little ‘battery management’ on his part.
8. Safety - When operating the SPR-365 the operator must wear protective eyewear,
either the type included with the kit, or others that provide a reasonable level of
Longwave protection from the intense UV irradiance. The level of irradiance from the
SPR-365 is about 100 times more intense than the sun on a clear day! Do not point the
SPR-365 at anyone’s eyes as Retinal damage is virtually assured. Short exposure to
indirect irradiance of from the SPR-365 should be kept to a minimum, but acceptable eye
protection is appropriate industrial practice..
