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.
