SPR-365 Operating Instructions

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, try the replacement 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 End Cap is simply turned clockwise to remove it.

The special Nickel–Metal Hydride battery has a unique ‘Double Contact End’, so it can be
placed in the housing in either direction.. To screw the Battery End Cap back on, rotate it
counter clockwise, but ensure it is threaded on straight so the threads are not damaged.

3. 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.

4. 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.

5” or 120mm

5. 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.

6. Battery Charging – To charge a SPR-365’s Nickel–Metal Hydride Battery, it must be

installed in the Housing, with the Battery End Cap securely tightened to the Body. First
Plug in the charger (100 to 240 VAC / 50 to 60Hz) to mains power. When this is done,
the Red LED will illuminate. When the Charger Connector is plugged into the Battery
Charger Receptacle, the Red LED will turn off and the Green LED will come on. If there is
a fault in the charging system, the Red LED will flash.

The 3.7 Volt / 2600 mAmp-Hour Nickel–Metal Hydride Battery will take approximately 3 ½
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 3 ½ 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.

The SPR-365 can be operated with the charger plugged in, however the battery should
have at least 20% of its capacity in reserve. The SPR-365 should not be used

indefinitely with the charger plugged in, and should only be used as a ‘stop gap’ measure.

6. 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..
