Digital Multi-Meter

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.
