CAUTIONS

 

Improper use of this meter can result in damage, shock, 
injury or death. Read and understand this instruction manual 
before operating the meter. 
Always remove the test leads before replacing the battery. 
Inspect the condition of the test leads and the meter itself for 
any damage before operating the meter. Repair or replace 
any damage before use. 
Use great care when making measurements if the voltages 
are greater than 25VAC rms or 35VDC. These voltages are 
considered a shock hazard. 
Remove the battery if the meter is to be stored for long 
periods. 
Always discharge capacitors and remove power from the 
device under test before performing Diode, Resistance or 
Continuity tests. 

  Voltage checks on electrical outlets can be difficult and    

misleading because of the difficulty of connecting to the 
recessed electrical contacts. Other means should be used 
to ensure that the terminals are not "live". 

  If the equipment is used in a manner not specified by the  

manufacturer, the protection provided by the equipment 
may be impaired.
