Silicon Carbide
(SIC) Photodiode packaged in hermetically sealed UV glass window
cap.
Interference filter coating (Metal Oxide) blocks most UVA from
response
Operating
Press and hold
push-button switch on face of unit. Aim sensor window in top panel of
meter
directly at UV source. Note reading on LCD and record if desired. For reptile
lamps
also check at "basking" position.
Battery
Battery
operation voltage is 3V down to 2.5V. Below 2.5V the LCD numbers will begin
to
dim, indicating the need for battery replacement. Under "typical" service
load, the battery
should last about 1 year.

Proper Usage of RGM-UVB meter for Lamp
Aging Tests
- Wear eye protection when checking UV lamps
(UV-block wrap around glasses).
- Allow lamps to warm-up prior to taking
readings (at least 5 min).
- When checking aging of lamps, keep measuring
distance and locations constant.
- Lamps should be replaced when output drops
30% to about 70% of their original (new) readings. Take overall reading at
exposure distance, or check individual lamps close to surface. Keep track of
hours vs. readings on a chart.
- If unsure of what original new values were,
replace lamp(s) with new ones of the same kind and compare to old ones.
-
When checking UVT acrylic transmission, take reading through acrylic; then
remove acrylic and hold meter sensor at approximately the same distance from
lamp as the acrylic shield was located. If acrylic blocks much UVB it should be
replaced.
- When using this meter to compare different type lamps, due to
their different spectral power distributions, the readings should be considered
relative rather than absolute. Although higher output lamps of similar SPD's
will generally read higher than lower output lamps, ones that peak near 290-300
nm (as does the meter response) will read higher than ones peaking near 313 nm
even if the total UVB output of both is the same.
- 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.
