Warning - MSA Sirius Manual De Operación

NOTE: After set-up, the instrument will display:
"Warning - 100 ppb increments - see manual".
Press the ON/OFF button to acknowledge the warning and
to continue.
The VOC Auto-range displays readings in increments of 100
ppb from 0 to 9900 ppb. Do not rely on the value of the last
two digits (00). Failure to correctly interpret the reading
could result in VOC over-exposure.
• Display reading will flash between the reading and
"ppb" for readings less than 9900 ppb (9.9 ppm).
• Select OFF for PPM
• Response Factor Page (turns the RF Page ON or OFF)
• Response Factor Save (if OFF, instrument always returns to
Isobutylene at turn-ON)
• Response Factor Favorites:
• Select the five favorite VOC gases for quick selection when
changing response factors (See Chapter 3, PID Setup)
• Response Factor Change (see Chapter 3, PID Setup).
NOTE: Alarm values for PID have limits based on sensor
performance. The Low alarm, STEL, and TWA cannot be
set below 2.0 ppm and High alarm cannot be set below 10
ppm.
It is very important to have an understanding of PID basics
when changing your PID settings. Failure to properly identi-
fy the VOC gas being measured and/or failure to select the
correct Response Factor alarm values (exposure, STEL,
TWA) that match your desired Response Factor and/or the
correct bulb, will result in erroneous readings that could
lead to serious injury or death.
