WARNINGS

Check the meter before use to make sure there was no damage during 

   transit.

Check that the insulation on the test leads is not damaged and/or wires 

   are not exposed.

If any faults or abnormalities are observed, the meter should not be used 

   and should be checked out prior to use.

Never exceed the protection limit values indicated in specifications for 

   each range of measurement.

Always be careful when working voltages above 60V DC or 30V AC rms, 

   keep fingers behind the probe barrier while measuring.

Make sure the rotary switch is in the correct position before measurement.
Never use the meter in an environment with explosive gas, vapor or dust.
Always keep fingers behind probe barriers when making measurements.
When connecting test leads to a circuit, connect the black test lead first, 

   then the red lead.  Disconnect in the opposite order.

Turn off power and discharge all capacitors first before measuring 

   resistance, continuity or diodes.

Failure to follow safety guidelines could compromise the safety features 

   of this meter.

Do not use the meter without the battery cover in place.
Replace the batteries as soon as 

 

  “       ” to avoid 
  false reading that could lead to electric shock and injury.

Remove test leads from all circuits before opening the battery cover.
