flammable gasses, fumes, vapor or dust. Otherwise, the use of the 

instrument may cause sparking, which can lead to an explosion. 

The  transformer  jaws  are  made  of  metal  and  their  tips  are  not 

insulated. 

 Where  equipment  under  test  has  exposed  conductive  parts,  be 

especially  careful  about  the  hazard  of  possible  shorting.  Not 

following this instruction may can danger to the user. 

Never attempt to use the instrument if its surface or your hand is wet.

Never  open  the  battery  compartment  cover  when  making 

measurement.

Never try to make measurement if any abnormal conditions, such 

as broken Transformer jaws or case is noted.

To avoid electrical shock by touching the equipment under test or 

its surroundings, be sure to wear insulated protective gear. 

The  instrument  is  to  be  used  only  in  its  intended  applications 

or  conditions.  Otherwise,  safety  functions  equipped  with  the 

instrument  doesn't  work,  and  instrument  damage  or  serious 

personal injury may be caused. 

#

 WARNING 

Adhere  to  local  and  national  safety  codes.  Individual  protective 

equipment must be used to prevent shock and arc blast injury where 

hazardous live conductors are exposed.

Never  attempt  to  make  any  measurement,  if  the  instrument  has  any 

structural abnormality such as cracked case and exposed metal part. 

Do  not  turn  the  Function  Selector  switch  with  test  leads 

connected to the instrument. 

Do  not  install  substitute  parts  or  make  any  modification  to  the 

instrument. Return the instrument to your distributor for repair or 

recalibration.

Do not try to replace the batteries if the surface of the instrument is wet. 

Always  switch  off  the  instrument  before  opening  the  battery 

compartment cover for battery replacement. 

Always be sure to keep your fingers and hands behind the Safety 

barrier. 

 (see 

 of 

4. Instrument Layout

) Otherwise, user may be exposed to 

the danger of electrical shock.

Always attach the Cap onto the tip metal parts when using the test lead 

in the Measurement Category III. (CAT. III) or higher environments. 

   When  the  test  leads  are  connected  to  the  instrument,  the  lower 

category (voltage) either of them belongs to is applied.
