Use of the fibrous dust filter or the incorrect paper filter for
the measurement of reactive gasses could cause
erroneous readings.
Place the new paper-like filter into the recess in the back of the
instrument. If it is to be used, place the fibrous dust filter into the
clear filter cover.
5. Replace the O-ring in the recess.
6. Re-install the clear filter cover on the back of the instrument.
4.6 Cleaning the Instrument
Clean the exterior of the instrument regularly using only a damp cloth.
Do not use cleaning agents as many contain silicones which damage
the combustible sensor.
4.7 Storage
When not in use, store the instrument in a safe, dry place between
65°F and 86°F (18 °C and 30 °C). After storage, always recheck
instrument calibration before use. If not to be used in 30 days,
remove battery pack or connect it to a charger.
