Signal Input
INPT:
Select the sensor or signal type for the desited signal input
Range:
(Thermocouple) J_TC, K_TC, T_TC, E_TC, B_TC, R_TC, S_TC, N_TC, L_TC
(RTD) PT.DN, PT.JS
(Linear) 4-20, 0-20, 0-60, 0-1V, 0-5V, 1-5V, 0-10
UNIT:
Select the process unit
Range: °
C, °F, PU (Process unit). If the unit is neither °C nor °F, select PU.
DP:
Select the resolution of process value.
Range:
For Thermocouple and RTD Signal NO.DP, 1-DP and For Linear Signal NO.DP, 1- DP, 2-DP,
3-DP
INLO:
Select the low scale value if using a linear input.
INHI:
Select the high scale value if using a linear input.
How to use INLO and INHI:
If 4-20mA is selected for INPT, let SL represent the low scale of the input signal (i.e. 4 mA),
let SH represent the high scale of the input signal (i.e. 20 mA). S represents the current input signal value;
the conversion curve of the process value is shown on the following page:
