CAUTIONS 

  Improper use of this meter can cause damage, shock, injury or death. Read and understand 

this user manual before operating the meter. 

  Always remove the test leads before replacing the battery or fuses. 

  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. 

  Warning! This is a class A equipment. This equipment can cause interference to devices in the 

home; in this case the operator can be required to carry out adequate measures to prevent 
interference. 

  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 uncertainty 

of connection 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. 

  This device is not a toy and must not reach children s hands. It contains hazardous objects as 

well as small parts that children could swallow. In case a child swallows any of the parts, 
please contact a physician immediately. 

  Do not leave batteries and packing material unattended; they can be dangerous for children. 

  In case the device is going to be unused for an extended period of time, remove the batteries 

to prevent them from draining. 

  Expired or damaged batteries can cause cauterization on contact with skin. Always use 

suitable hand protection. 

  See that the batteries are not short-circuited. Do not throw batteries into fire.
