must set a different address.If the devices are with the same address, it may not
be found by communicator,then a separate connection is required to modify the
polling address of the device.HART protocol defines the communication mode of
multiple devices connected in the same loop as multi-point communication mode.
The current of the loop is no longer 4-20ma, but the sum of the output current of
these devices.

Battery Power

Select the third item from the item menu to enter the display battery power

function, which will detect the remaining battery power in the current
communicator.When the battery power is too low, please replace the battery as soon
as possible, otherwise, it will affect the use of commnunicator.

Instrument Information

The fourth item in the project menu can enter the local information

interface.This interface can view the local version number and serial number

information.
