76 SDM3055 Digital Multimeter

Statistics Function:



In statistic function, the first reading is usually set to the maximum or

minimum value. When getting more readings, current displaying value
is always the maximum/minimum reading among all the measured
values.



The maximum, minimum, average and reading quantities are stored in

volatile memory.
