Loop check (3)
(1) The decimal point position is fixed for each differential pressure range. (Refer to section 10, Power-on Message).
The max. differential pressure can be set from the value which is 25%F.S above the minimum differential pressure.
The values under 25%F.S. cannot be increased or decreased by T, S key.
(2) For setting zero point and span point of the analog output, input the percent value over the maximum display span
(between OFFSET and FULL SCALE). Its decimal point position can be set up to one digit after the decimal point
(xx.x).
(3) Regardless of whether pressure is applied or not, the loop check can be activated which links the display and the
output allowing the operator to arbitrarily adjust the output to check the system, troubleshoot etc (using the T, S
keys), ref section 14.4. This example shows the display set to the span point.
