Troubleshooting

•

Symptom

Probable Cause

Comments

Noisy readings (fast

fluctuations)

Improper grounding of cable shield and/or

ISR 320

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 320

Non-uniform emissivity of large moving targets Slower response speed is

required.
