IMPORTANT SAFETY WARNINGS

 

 

WARNING

Read entire Safety Notes section regarding potential hazards and proper 

instructions before using this meter. In this manual the word “

WARNING

” is 

used to indicate conditions or actions that may pose physical hazards to the 

user. The word “

CAUTION

” is used to indicate conditions or actions that may 

damage this instrument. 

 

 

WARNING

To ensure safe operation and service of the tester, follow these instructions. 

Failure to observe these warnings can result in severe injury or death.

 

 

WARNING

•  Before each use, verify meter operation by measuring a known voltage  

  or current.
•  Never use the meter on a circuit with voltages that exceed the category  

  based rating of this meter. 
•  Do not use this meter during electrical storms or in wet weather.
•  Do not use the meter or test leads if they appear damaged. 
•  Ensure meter leads are fully seated and keep fingers away from the    

  metal probe contact when making measurements. Always grip the leads  

  behind the finger guards molded into the probe.
•  Do not open the meter to replace batteries while the probes are  

 

 connected. 
•  Use caution when working with voltages above 60V DC or 25V AC RMS.  

  Such voltages pose shock hazards.
•  To avoid false readings that can lead to electrical shock, replace  

 

  batteries if a low battery indicator appears.  
•  Unless measuring voltage or current, shut off and lockout power before  

  measuring resistance or capacitance.
•  Always adhere to national and local safety codes. Use proper personal  

  protective equipment (PPE) to prevent shock and arc blast injury where  

  hazardous live conductors are exposed.
•  Always turn off power to a circuit or assembly under test before cutting,  

  unsoldering or breaking the current path. Even small amounts of current  

  can be dangerous.
•  Always disconnect the live test lead before disconnecting the common  

  test lead from the circuit.  
•  In the event of electrical shock, ALWAYS bring the victim to the 

 

  emergency room for evaluation, regardless of victim’s apparent recovery.
   Electrical shock can cause unstable heart rhythms that may need  

 

  medical attention.
•  If any of the following occur during testing, turn off the power source to  

  the circuit being tested: arching, flame, smoke, extreme heat, smell of    

  burning materials or discoloration or melting of components. 

 WARNING

Higher voltages and currents require greater awareness of physical safety 

hazards. Before connecting the test leads, turn off power to the circuit under 

test, set meter to the desired function and range, connect the test leads to 

the meter first, then connect to the circuit under test. Reapply power. If an 

erroneous reading is observed, disconnect power immediately and recheck all 

settings and connections. 

 WARNING

This meter is designed for trade professionals who are familiar with the 

hazards of their trade. Observe all recommended safety procedures that 

include proper lock-out utilization and use of personal protective equipment 

that includes safety glasses, gloves and flame resistant clothing.
