1.1 INTENDED USE
The Impact/Impact Pro has been designed to alert the user to
potentially hazardous atmospheres whilst carrying out his/her
normal duties. Therefore, the instrument must be kept
switched on and worn as close to the breathing area as
possible, and several accessories are provided to allow the
instrument to be worn in a number of different ways:
a. On the chest
b. On a belt
c. Attached to a body harness
The instrument is provided with various methods to enable the
user to comply safely and easily with confined space
regulations.
CAUTIONS
Hand aspirated remote sampling only provides continuous
gas readings as long as the bulb is being operated.
Zellweger Analytics recommend that the instrument be
calibrated at least every 6 months or in accordance with
customer site procedures, whichever is sooner. Correct
operation of the instrument should be confirmed with test
gas of known concentration before each use.
The use of Enforcer calibration accessory is strongly
recommended as it enables this to be performed quickly
and easily.
WARNING
A sensor which cannot be calibrated or which is found to
be out of tolerance should be replaced immediately. For
the disposable cartridge a replacement cartridge must be
fitted.
