12.1 CLEANING
CAUTION: Do not use polishes containing silicon or
solvent to clean the instrument as these may
damage the flammable gas sensor. Do not use
abrasive materials or strong volatile chemical
solutions as these could damage the impact
resistant casing.
The outer, impact resistant casing of the GT series
instrument may be cleaned using a non-abrasive moist
cloth. Rub the cloth over the outer casing to remove any
dirt and grime.
In extreme cases, a mild soap solution may be used with
a non-abrasive cloth to remove more stubborn marks.
12.2 FILTER REPLACEMENT
The instrument has a hydrophobic type filter protecting
the instrument sensors. The filter is located in the probe
and should be inspected periodically for signs of
contamination and / or damage.
