Time Settings and Data Logging
Instrument Clock
Note: The real-time clock is part of the advanced option package.
The instrument has a real-time clock for recording logged events. The clock
displays the time and the date. The date format can be set to European
format (day/month/year) or American format (month/day/year). The time
clock uses the 24-hour format.
The clock will continue to operate for up to 5 years (typically) on the
internal battery if there is no power connected to the instrument. Therefore,
after an interruption to the power supply, the instrument recommences
normal operation although there will be no data recorded during the period
without a power supply.
RTU DATA The Modbus RTU data format for the 2-register (4-byte) values can be
set as either floating point or long integer values.
Use or to select FLOAT or INTEGER.
RTU ADDR The Modbus RTU protocol address must be in the range of 1 to 247.
When multiple instruments (slaves) are connected to one communication
device (master), each assigned address must be unique.
Note: The master device uses the RTU address 0 (zero) for broadcasting
to all connected slave units.
ASCII ADDR The ASCII protocol address identifies each communicating device.
The address must be in the range of 1 to 255. When multiple instruments
(slaves) are connected to one computer (master), each assigned address
must be unique.
FLASH PORT The Flash Driver Port assignment defines the communication port for
downloading software into the instrument.
The default setting of this assignment is the RS-232 port. The Ethernet
port, if fitted, can not be used as the Flash port.
Press or to select RS-232 (COM-1), RS-485 (COM-2) or
NONE.
