

Do not

 use the calibrator if it is damaged. Before you use the 

calibrator, inspect the case. Look for cracks or missing plastic. Pay 
particular attention to the insulation surrounding the connectors. 



Select the proper function and range for your measurement. 



Make sure the battery cover is closed and latched before you 
operate the calibrator. 



Remove test leads from the calibrator before you open the battery 
door. 



Inspect the test leads for damaged insulation or exposed metal. 
Check test leads continuity. Replace damaged test leads before 
you use the calibrator. 



When using the probes, keep your fingers away from the probe 
contacts. Keep your fingers behind the finger guards on the probes. 



Do not

 use the calibrator if it operates abnormally. Protection may 

be impaired. When in doubt, have the calibrator serviced. 



Disconnect test leads before changing to another measure or 
source function. 



To avoid false readings, which could lead to possible electric shock 
or personal injury, replace the battery as soon as the battery 
indicator appears. 



To avoid personal injury or damage to the calibrator, use only the 
specified replacement parts and do not allow water into the case. 

 

 

 

Caution…

 



Disconnect the power and discharge all high-voltage capacitors 
before testing resistance or continuity. 



Use the proper jacks, function and range for your measurement or 
sourcing application. 



To avoid damaging the plastic lens and case, 

do not

 use solvents 

or abrasive cleansers.
