If pressure range is -760mmHg to 3kg/cm
2
, pressure transmitter outputs 4 to 20mA, and it
displays -760mmHg for 4mA input and 8mA is unit changing point. For 20mA input, it displays
3kg/cm
2
.
Unit changing point = (
16
X+1.033
× Y) + 4
16 4-20mA output interval
X Max. value of pressure range (E.g.: For -760mmHg to 3kg/cm
2
, it means "3")
1.033 Converted value from 760 mmHg to kg/cm
2
unit value (same unit)
Y Use pr 1.033 (E.g.: used pressure is ‘0’, it is 1.033)
4 Min. value of output (when output is 0) 4.00mA

When fixing low-limit scale value and high-limit scale value and set gradient, input range is 0
to 10V, low-limit scale value is 0.00, high-limit scale value is 10.00, the display values are as
below by changing gradient as 0.500, 1.000, 1.500.

When fixing low-limit scale value and high-limit scale value and set gradient (subtraction
gradient), input range is 0 to 10V, low-limit scale value is 10.00, high-limit scale value is 0.00,
the display values are as below by changing gradient as 0.500, 1.000, 1.500.
