  Disconnect circuit power and discharge all high-voltage capacitors before

     testing resistance.

  Replace the battery as soon as the battery indicator  

 appears or no display

     when turning on the Meter.  With a low battery, the Meter might produce
     false readings that can lead to electric shock and personal injury.

  Before carrying out any measurement, make sure the Meter is in good

     condition after turning it on.

  When servicing the Meter, use only the same model number or identical

     electrical specifications replacement parts.

  The internal circuit of the Meter shall not be altered at will to avoid damage

     of the Meter and any accident.

  Soft cloth and mild detergent should be used to clean the surface of the

     Meter when servicing. No abrasive and solvent should be used to prevent
     the surface of the Meter from corrosion, damage and accident.

  Turn the Meter off when it is not in use and take out the battery when not

     using for a long time.

  Constantly check the battery as it may leak when it has been using for some

     time, replace the battery as soon as leaking appears.  A leaking battery will
     damage the Meter.
