Retransmission base scale (Setting range: 0.0 to 100.0%) (Option)Retransmission span scale (Setting range: 0.0 to 100.0%) (Option)[Description]• The retransmission base scale and span scale can be setas shown below. Unit for the setting is %. PV/SV/DV Percentage of input measurementrange (Note 1)MVOutput valueNote 1: Calculate the set value by using the following formula(refer also to the setting example shown below).Set value (%) = (A ÷ B) × 100 [%]A = Temperature to be set – Set value of parameter "P-SL"B = Set value of parameter "P-SU" – Set value of "P-SL"• When the value of retransmission output (example: SV)becomes equal to the set value of Ao-L, the retransmissionoutput becomes 0% (output).• When the value of retransmission output (example: PV)becomes equal to the set value of Ao-H, the retransmissionoutput becomes 100% (output).Related parameters: (page 67)[Note]• Be sure to always set smaller than .[Setting example] At K thermocouple input of 0 to 400˚C, make the setting so that the PV (valueof retransmission output type) becomes 0% at 100˚C, and 100% at 300˚C.Since the measurement range is 0 to 400˚C, P – SL = 0 (lower limit value of measurement range), and P – SU = 400 (upperlimit value of measurement range). So, from the formula shown above,A = (100˚C – 0) or (300˚C – 0), B = 400 – 0 = 4001) Setting Ao-L : What position is 100˚C in the temperature range from 0 to 400˚C ? = 25% (=(100 – 0) ÷ 400 × 100 [%]) Ao-L = 25.0 (%)2) Setting Ao-H : What position is 300˚C in the temperature range from 0 to 400˚C ? = 75% (=(300 – 0) ÷ 400 × 100 [%]) Ao-H = 75.0 (%)DisplayPV indicationSV indicationPV indicationPress and hold the SEL for five seconds.will be displayed.Press the key to display .Press thePress the or key to flicker and to display .Press the SEL key once. will be displayed and will be registered for the retransmission base scale.(Repeat the procedure from 3 to 5 to check the set value.)Press the key to display .Press theOperating procedureSEL key once.
