Symptom Probable Cause Comments
Noisy readings (fast
fluctuations). Target moves more than 95%
out of field of view. Conveyor
type applications will also cause
fluctuations as targets move by
the field of view.
Application may require
Maximum to be stored. Apply
t
clear
settings. See section 4.6.2.
Target may be changing
temperature quickly.
(Thermocouples do not respond
as fast as the ISR 6). Speed of response may be
slowed down
Apply t
90
settings. See section
4.5.
Target may be reflecting nearby
objects that have fluctuating
temperatures.
Loose connection in wiring.
Electrical noise lead wires caused
by intense magnetic fields,
improper selection of inter-
connecting cable.
Noisy readings (fast
fluctuations).
Cable run into in same conduit as
AC power lines.
Improper grounding of cable
shield and/or ISR 6 housing.
Flame or reflections of flame
may be entering the field of
view.
Extremely dense steam, smoke,
thick dust, personnel or moving
machinery intermittently
blocking 95% of optical path of
ISR 6.
Non-uniform emissivity of large
moving targets. Slower response speed is
required.
Faulty ISR 6. Contact LumaSense. See section

fails The instruments internal
temperature is higher than 55°C. Use cooling jacket.
