Digital process meter DMP 11 provides physical value measuring with
displaying it within -60000 to +60000 digits range. Internal analogue
sigma-delta converter offers resolution of one digit even in full scale
range. Device provides adjustable input signal scale, output signal
scale, decimal point and etc. to fit any kind of application. User can even
set his own calibration for current, voltage (low, high) and potencimeters
signals. Potencimeter measuring is based on the ratio measurement,
slow changes in total potentiometer resistance do not affect
measurement accuracy. Device has implemented NAMUR NE43 input
current loop 4-20mA checking, with defined behaviour in case of current
loop error.
