Telescoping Handle 
Congratulations on your purchase of this Extech Telescoping Handle. This accessory can be used 
with several Extech meters to enable measurements in areas normally unreachable. 
Operation 
The meter sensor is attached to the top of the pole using the tripod screw. 
1.  Release the head cover (3) by pressing the two release 
latches (1). 
2.  Secure the meter to the head tripod screw (2) and replace the 
head cover 
3.  Adjust the head to the needed angle and tighten with the 
locking screw (4) 
Extend the pole sections by twisting the locking nuts as shown and then securing at 
the desired length. 
NOTE: The extended pole should only be used in the vertical position. If 
used in the horizontal position with the pole extended the meter’s weight 
will damage the mechanism.
