Sensor/Detector
GaP Photodiode packaged in hermetically
sealed UV glass window cap.
Schott color glass filter to narrow response
as shown on spectral response graph.
Operation
Press and hold push-button switch on face
of unit. Aim sensor window in top panel
of meter directly at blue light source.
Note reading on LCD and record if desired.
Battery operation voltage is 9V down to
6.5V. Below 6.5V the LCD numbers will
begin to dim, indicating the need for
battery replacement. Under "typical"
service load, the battery should last
about 2 years.

Proper
Usage of Solarmeter ® Ultraviolet Radiometer
for Lamp Aging Tests
- Wear actinic eye protection when checking
blue lamps.
- Allow lamps to warm-up prior to taking
readings (at least 5 min).
- Hold meter integral sensor close to source
to measure individual lamp or LED intensity.
Hold sensor at working distance from source
for effective intensity.
- When checking aging of lamps, keep measuring
distance and locations constant.
- Lamps should be replaced when output drops
to about 70% of their original (new) readings.
- If unsure of what new values were, replace
a lamp with new one and compare old one.
- Do not subject the meter to extremes in
temperature, humidity, shock or dust.
- Use a dry, soft cloth to clean the intrument.
Keep sensor free of oil, dirt, etc.
