Detailed Product Description

  72*72 Digital DC ammeter ampere meter

This series instrument is divided into the direct current ammeter and alternating current ammeter according to the different input signal type, direct
input and accessory device input according to the different input ways of measurement wiring.  When direct input, the instrument specification is
AC0~5A or DC0~5A and measurable any current value within the range of 0~5A. When accessory device input, the instrument specification is respectively
AC0~1999A, 0~1500A (accessory transformer) or DC0~1999A, DC0~1500A (accessory electrical shunt). Through setting the interior measuring range
switching device of the instrument, it can expand more specifications on these four kinds of specification foundation. The switching device for measuring
 range is on the display function panel of the instrument. It is made up of altogether 18 pins and divided into 9 groups. Each group is assigned the
corresponding serial number and then arranged according to a certain order (The arrangement ways of instrument with different shape are maybe
different, but their serial number is corresponding.) When shorting on every group of pins according to a specific rule, it can realize the switching on
instrument display measuring range. Below is the instrument specification tabulation which the jumper position corresponds (The instrument is altogether
divided to five kinds of specifications respectively, user may choose any one among them and others not included need custom-made according to
special specification)
