2. DESCRIPTION 
-  This  meter  is  a  portable  professional  measuring 
instrument  with  large  LCD  to  show  three  lines  of 
readings, as well as back light for easily reading.   The 
‘single-hand  operation’  design for  the  range  switch 
makes  measurement  simple  and  easy.    Overload 
protection and low battery indication are provided.    It 
is  an ideal multi-function instrument with scores of 
practical  applications  for  professional,  workshop,

prevent  misconnection  of  test  leads  and  provide 
additional  protection  against  damages  caused  by 
improper operation. 
- The  5 in  1 digital  multi-tester  has  been  designed  to 
combine  the  functions  of  sound  level,  luminance, 
humidity and temperature meters, as well as a digital 
multimeter. 
- The  sound level function is applicable  to measuring 
noise level in factories, schools, offices, airports and at 
home,  and  for  checking  the  acoustics  of  studios, 
auditoriums and hi-fi installations.   
- The luminance function is applicable to measuring field 
luminance  with  full  cosine  correction  for  angular 
incidence of light.
