    Electrical Specifications: (23℃±5℃)    
    The following accuracy is specified for one single channel (channel 1 or channel 2).   
     If dual channels are used at the same time, additional % of accuracy should be added to the listed accuracy.  
    Please refer to the supplemental dual channels specification.      
    The following accuracy is also specified for the ZEROED (relative) value.   
     The accuracy is given as ±% of reading ± number of least significant digits.
