3. Select the electron voltage of the desired bulb.
• If instrument is setup for use with a bulb other than the default 10.6
one, current bulb voltage will be displayed at turn ON.
It is very important to have an understanding of PID basics
when changing your PID settings. Failure to select the cor-

that match your desired Response Factor, and/or the correct
bulb, will result in erroneous readings that could lead to
serious injury or death.

(only if equipped with 9.8 eV lamp)
When used on the Sirius PID with a 9.8 eV lamp, the MSA Benzene
scrubber tubes will:
• scrub most other background VOCs from benzene
• allow for a benzene specific reading with an average accuracy of
20% (0-100 ppm).
Conditions of use:
• temperature range of 5°C to 40°C (41°F to 104°F)
• RH of up to 30g/m³ at 104°F .
1. turn unit ON.
2. Mount the tube holder with quick-connect fitting on the Sirius
