u Sensor parameter function description

pour1．（Sn）Set the corresponding code based on the sensor model. See (Table)1）↑

pour2．（dot）Set the decimal point position of the measured value, and the parameters that change with the decimal point are as followsPVL、PVH、OBL、OBH、PbIA、AL1、HAL1、AL2、HAL2

pour3．（PvL）Set the corresponding display value when the sensor has zero input

pour4．（PvH）Set the corresponding display value when the sensor is fully input

pour5．（Pb）Used to correct the zero point error of the sensor, the relationship with the displayed value is as follows: current measurement current value=Actual measured display value*K1+Pb

pour6．（K1）Resignation is used to correct the slow point error of the sensor, and its relationship with the displayed value is as follows: the current measured display value=Actual measured display value*K1+Pb

pour7．（InPL）Set the minimum value of the input signal only whenSn=16perhaps17It needs to be set only when a millivolt signal or resistance signal is input.

pour8．（InPH）Set the maximum value of the input signal only whenSn=16perhaps17It needs to be set only when a millivolt signal or resistance signal is input. Peijie's remote transmission pressure gauge0~375Set Ω input as an example:InPH=375，InPL=0

pour9．（FILT）The larger the filtering coefficient, the more stable the display, and then it becomes larger.

pour10．（DISP）Set the instrument to display in the measuring state againSVshow contents

pour12（obL）Set the measurement value corresponding to the zero point of the transmission output.

When settingobLgreater thanobH, can display inverse ratio transmission20~4mA.

pour13（obH）:Set the measurement value corresponding to the output slow point for a hundred years.

pour14（PEAK）：PEAK=0When, use the measured value as the transmission output.

PEAK=1At this time, the peak value is used as the transmission output.
