Figure 5.22 Current calibration tab
The current calibration steps are as follows:
(1) Connection circuit, need to be connected to the device output circuit in series with more than five and a
half precision ammeter;
(2) Set the device's polling address to 0, refer to basic information configuration, if the polling address is 0,
skip this step;
(3) Enter the current calibration tab;
(4) Select "current value" as 4mA, after the ammeter is stable, enter ammeter reading in "adjust value" text
box, click "apply";
(5) Select "current value" as 20mA, after the ammeter is stable, enter ammeter reading in "adjust value"
text box, click "apply";
(6) Select “current value” as blank so that the output current of the device is calculated according to the PV
value.
Configure current fixed output:
The user can configure the fixed current output in the current calibration tab, enter the output fixed current
value in the “fixed current value”, and click “enter/exit fixed current mode” to enter or exit fixed current output
mode. The title of the button alternately displays "enter fixed current mode" and "exit fixed current mode" to
prompt the user to operate.
Notes:
The calibration current and fixed current output function can only be processed t when the polling address of
the device is 0, and the other polling addresses are in full digital communication mode, which will prompt the
error message "command execution failure ".

Variable monitoring
The primary function of the variable monitoring tab is to regularly refresh all the dynamic variables of the
selected device and display the trend curve of the current device main variable. the variables currently refreshed
