The BATDT-M has a battery monitor feature which illuminates when the lithium battery voltage approaches its end

of life. A descriptor, “BAT”, illuminates when the battery voltage falls below this predetermined value. The low bat-

WIRING

A 10 point linearization table is used to construct a curve describing the relationship of K-Factor and input frequency.

The measured input frequency is used to access the table. A linear interpolation of adjacent point pairs is used to

arrive at the K-Factor at that input frequency. The ﬂ ow rate and total are then computed based upon the K-Factor

for that measurement sample.

For best performance and resolution choose as many decimal places as possible in the K-Factor.

Example: Enter a K-Factor of 1 as 1.000.

Apendix A: Modbus RTU Protocol

When the BATDT-Millennium is equipped with the Modbus option, the protocol it uses is the Modbus RTU pro-

tocol. This protocol deﬁ nes a message structure that hosts and clients will recognize and use on the Modbus

access to another device (BATDT-Millennium), how it will respond to requests from the other devices, and how

errors will be

detected and reported. It establishes a common format for the layout and contents of message ﬁ elds. During

communications on a Modbus RTU network, the protocol determines how each BATDT-Millennium will know its

device address, recognize a message addressed to it, determine the kind of action to be taken, and extract any

data or other information contained in the message. If a reply is required, the BATDT-Millennium will construct the

The BATDT-Millennium with Modbus communications option supports the Modbus RTU (Remote Terminal Unit)

character density allows better data throughput than ASCII for the same baud rate. The Modbus RTU uses a Mas-

ter-Slave Query-Response Cycle in which the BATDT-Millennium is the slave device.

The BATDT-Millennium with Modbus communications option supports the following function codes:

01 Read Coil Status Reads the status of a coil (ON or OFF)

03 Read Holding Registers Reads the value in a holding register

05 Force Single Coil Forces a single coil (0x reference) to either ON or OFF

06 Preset Single Register Presets a value into a single holding register (4x reference)

15 Force Multiple Coil Forces each coil (0x reference) in a sequence of coils to either ON or
