Rounding Feature (round)
The rounding feature is used to give the user a steadier display with
fluctuating signals. Rounding is used in addition to the filter function.
Rounding causes the display to round to the nearest value according to
the rounding selected. This setting affects the last two digits, regardless
of decimal point position.
Modbus RTU Serial Communications (serial)
The meter is equipped with serial communications capability as a
standard feature using Modbus RTU Serial Communication Protocol.
To communicate with a computer or other data terminal equipment, an
RS-232, RS-485, or USB adapter option is required; see Ordering
Information on page 7 for details.
Warning!
Do not connect any equipment other than Precision
Digital’s expansion modules, cables, or meters to the
RJ45 M-LINK connector. Otherwise damage will occur
to the equipment and the meter.
Note: More detailed instructions are provided with each optional serial
communications adapter. Note: Refer to the ProVu® Modbus
Register Tables located at www.predig.com for details.
Note: Changes made to the Serial menu are initialized after the menu
key is pressed or after navigating through the remainder of the
serial parameters (i.e. pass the t-byte parameter).
When using more than one meter in a multi-drop mode, each meter
must be provided with its own unique address. The meter address
(Slave ID) may be programmed between 1 and 247. The transmit delay
may be set between 0 and 199 ms. The parity can be set to even, odd,
or none with 1 or 2 stop bits.
Changes made to the Serial menu are initialized after the MENU key is
pressed or after navigating through the t-byte parameter.
