  Do not exceed the maximum allowable input range of any function. 

  Do not apply voltage to meter when resistance function is selected. 
  Set the function switch OFF when the meter is not in use. 
  Remove the battery if meter is to be stored for longer than 60 days. 

  Set function switch to the appropriate position before measuring. 
  When measuring volts do not switch to current/resistance modes. 
  Do not measure current on a circuit whose voltage exceeds 600V. 
  When changing ranges always disconnect the test leads from the circuit under test. 

  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. 

  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.
