OPERATION 

1.  Before using instrument, the battery must 

be installed.  This is accomplished by 
sliding the battery cover on the back of the 
instrument (near the bottom) away from the 
case.  Once battery compartment is opened, 
a 9-volt battery can be clipped to the 
battery strap.  (

WARNING

: Use one of 

the types listed on page 11 to maintain 
intrinsic safety.

) Once properly seated, the 

battery cover is replaced using the opposite 
sliding motion used to remove it. 

2.  Slide probe from inside case by grasping 

the finger grips on the top of the probe.  
Once fully extended, the probe can be 
rotated 180 degrees to allow the meter to 
be easily read in air flows coming from 
various directions.  When in use, the probe 
must be turned so that the air flow is in the 
same direction as the arrow on the top of 
the probe.   

3.  Slide switch on the top of the instrument to 

the battery position.  Note the position of 
the needle on the instrument face.  It 
should be in the dark battery zone on the 
right hand side of the meter.  The further to 
the right the needle moves, the longer the
