Contrec 515 FA01, Operation Manual

Introduction
515 FA01 - 29 August 2021 5
Software Configuration
The instrument can be programmed to suit the particular application needs
and the flexible I/O can be assigned as required. Program settings can be
changed either via the front panel (depending on assigned access levels) or
via the 500 Series Program Manager (500-PM software).
The 500-PM software is a free comprehensive configuration tool and
resource centre that can be used to further tailor an instrument to suit
specific application needs including units of measurement, custom tags and
text, access levels and more.
The software is a Windows based program that is freely available from the
download section of the Contrec website. The program can be used to create
a custom version of an existing application to be saved for backup purposes
and/or to generate a PDF of configuration report for record keeping.
The instrument stores all set-up parameters, totals and logged data in non-
volatile memory with at least 30 years retention.

Limitations of Use
Negative Resultant Flow
In subtraction mode the instrument is capable of calculating and displaying
a negative resultant flow when Flow 2 is greater than Flow 1. However it
can not represent this with a retransmission output pulse. The pulse output
will only represent positive resultant flow, i.e. Flow 1 > Flow 2.
