Battery Replacement

Always use a fresh replacement battery of the specified size and type. 
Immediately remove the old or weak battery from the meter and 
dispose of it in accordance with your local disposal regulations. Old or 
defective batteries can leak chemicals that corrode electronic circuits.

            

WARNING!

To avoid electric shock, be sure to turn off the meter’s power and  
disconnect thermocouples from any equipment before you remove  
or install batteries.

 

To install a new battery, follow these procedures:

    1.  Remove the screws from the battery compartment cover on the  
    back of the meter and lift the cover (Fig 1).

    2.  Remove and discard the old batteries. Always dispose of old  
    batteries promptly in a manner consistent with local disposal  
   regulations.

            

WARNING!

Under 

NO

 circumstance should you expose batteries to extreme heat 

or fire as they may explode and cause injury.

    3.  Place a fresh batteries in the compartment.

NOTE:

 

If you do not plan to use the meter for a month or more, 

remove the battery and store it in an area that won’t be damaged by 
a leaking battery.

    4.  Reattach the battery compartment cover to the meter and  
    reinstall the screws.

These guidelines will help you attain long and reliable service from 
your meter:

    1.  Calibrate your meter annually to ensure it meets original  
    performance specifications.

 
    2.  Keep your meter dry. If it gets wet, wipe it dry immediately. Liquids  
    damage electronic circuits.

 
    3.  Whenever practical, keep the meter away from dust and dirt, which  
    can cause premature wear.

  
    4.  Although your meter is built to withstand the rigors of daily use, it  
    can be damaged by severe impacts. Use reasonable caution when  
    using and storing the meter.

Cleaning and Decontamination

Periodically clean your meter’s case using a damp cloth. 

DO NOT

 use 

abrasives, cleaning solvents or strong detergents, as they may damage 
the finish or affect the reliability of the structural components.

Storing the Thermocouples

The thermocouples with wire spools can be stored in the back of the 
thermometer.

    1.  Wind the wire around the wire spool.

    2.  Thread the end of wire through a hole of the wire spool. 

    3.  Thread the end of wire through the other hole of the wire spool.

    4.  Insert the end of wire under the loop and pull the end of wire.
