Figure 3-10 Off-line calibration wiring diagram
The current and voltage are the basic wiring connection. When the measuring and control
unit/RTD is binary output, the dotted line with arrowhead in the left will be connected with binary.
While calibrating power transmitter, the dotted line with arrowhead in the right will be connected
with DC.
3.11.2 Calibration Operation
1. Entering into calibration function interface
In the main interface, select function unit by rotary encoder and enter into function unit interface.
2. Setting parameters
Select parameter setting by rotary encoder in function unit interface.
Press encoder and adjust the current parameters. While adjusting, press function key 5
and switch the adjustment speed (coarse/fine/micro adjustment)
Setting different parameters, the soft keyboard in the below of the screen might remind
certain special operation.
