This series products have adopted surface packageing technology, which has greatly improved anti-interference capability, and have display, control, transmision communication functions and universual signal input. Through changing inner parameter can realize the switch of any signal type in table 1. They are widely used in many fields such as electric power, metallurgy, chemicals, petrochemicals, papermaking, printing and dyeing, brewage, tobacco, and space base and so on.

When the sensor was disconnected, displays OH means transmitting output maximum or displays OL means output minimum.3.4.10 Set Upper and lower limit of light column display: See table 4 for user parameter PVL and PVH.3.4.11 Set measured small-signal removal: in the field of measuring flow, when flow is smaller, measured value undulation is bigger, and error is bigger. the usual method is small signal removal. User parameter (table 4) SLU meanings shows % of range, that is, when (measured value =range) X % ≤ .SLU setting value, the instrument shows 0. Instrument has small signal removal function only when it with evolution function.3.4.12 Methods to return to measure state:•Manual return: Under parameter setting mode, pressing SET key for 5 seconds the instrument will automatically return to measured value display state.•Automatic return: Under parameter setting mode, does not press any key for 30 seconds, the instrument will automatically return to measured value display state.•Reset return: Under parameter setting state, pressing RESET key, the instru-ment will enter measured value display after self-check again.3.4.13 Display content of thermo-resistance, thermocouple disconnection instru-ment: when the ten’ s place of SL8 parameter is 0, instrument display OL or OH; when the ten’ s place of SL8 is not 0, instrument display Err.

Calibration of display transmit measure
6.1 Calibration of display range: When error exists between H/L limit display range and actual range, range can be adjusted by modifing Pbl and KK1, the details are as the following method:ICIC1= scheduled range ÷ display range X initial Kk 1 (scheduled range: SLH-SLL)Pbl= lower limit of scheduled range—lower limit of display range X KU +initial Pbl
For example: a DC current 4-20mA input instrument, measuring rang is200-1000Kpa, while calibration, find that when input 4mA, displays-202, when input 4mA, displays 1008. (Initial Pb171, initial KK1=1)
According to the formula:KK1=scheduled range ÷ display range X initial KK1= [1000- (-200)] ÷ [1008+202)] X 1= 1200+1210 X 1 0.992
Pbl= lower limit of scheduled range-lower limit of display range X KK1+ initial Pbl= -200- (-202 X 0.992) +0=0.384≈0.4Set: Pb17,1.4, KK1 .992
6.2 Calibration of transmission range: When error exist between H/L limit transmission output and actual range, range can be adjusted by modifying Pb3 andKK3, the details are as the following method:KK3= scheduled output range ÷ actual output range X initial KK3 (Scheduled output range: OUH-OUL)Pb3 = scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3
For example A DC current signal 4″-20mA input instrument, measuring range is -200-1000Kpa, transmission output is 4-20mA; While calibration, find that the instrument display is very accurate; when input 4mA and 20mA, the instrument output 3.9mA and 20.1mA respectively, set initial instrument Pb3=20.0, KK3=1.000.
According to the formula:KK3=scheduled output range ÷ actual output range X initial Kk3= (20-4) ÷ (20.1-3.9) X 1.000= 164-16.2 X 14.988Pb3= scheduled lower limit output-actual lower limit output X Kk3 + initial Pb3= 4-3.9 X 0.988 +20.0 =20.1Set: Pb3=20.1, Kk3=0.988
Note: Before calibrating transmission output, first ensure that the display is correct or not, Pbl, Pb3 modified value precise to one digit behind decimal point.
