User Manual 

Press the Select Button to Hold the 
Measurements 

 

When the measurement results stabilize, press 
the Select button to “hold” the measurement 
results. 

¾

 

Keep the instrument motionless 

when pressing the Select button to 
hold measurements, movement will 
cause readings to fluctuate.  Note 
that using the external sensor with 
magnet attachment provides more 
stable measurement results. 

¾

 

It is recommended that you take 

infrared temperature measurements 
with the instrument’s probe tip 
pressed against the machine, and 
never from more than 4” (10 cm) 
away from target. 

 

Measurement results freeze, HOLD appears on the 
display, and alarm indicators appear for the overall 
vibration and bearing vibration measurements if their 
measurement results exceed limits for the specified 
machinery classifications.
