3.1 
Operating Precautions  
(Please Read) 
 
To ensure that the gas sensors are properly zeroed at startup, the Hi 
Flow Sampler must be turned ON in clean air (free of combustible gases 
or vapors). 
 
Calibrate the instrument about every 30 days to assure its accuracy. The 
frequency of calibration, however, may change depending on how often 
the instrument is used and the amount of gas that was sampled. Create 
a maintenance log to keep track of when an instrument was calibrated, 
and then use this log to help develop a calibration schedule. For 
example, an instrument that fails its calibration after only being 
calibrated a single time should be calibrated more often. 
 
Important:
 Avoid sampling leaded gasoline vapors, or gases or vapors that 
contain silicones or sulfur compounds. Tetraethyl lead, silicones, and 
sulfur compounds can form contaminating compounds on the sensor 
element (poison the sensor), with resulting loss in sensitivity.
 
 
Always purge the instrument with clean air after testing. This removes 
combustibles from the sensor chambers and prolongs the life of the 
sensors. 
 
3.2 Battery 
Connection 
 
WARNING:
 Explosion hazard! DO NOT connect or disconnect the battery in 
an unsafe atmosphere. 
 
The instrument’s power cord is located inside the backpack’s right-side 
pocket. Insert a battery pack into this pocket and connect it to the power 
cord.
