: For some PLCs and systems using Modbus RTU, you may need to offset the register by 1. For
example, 3300 would become 3301.

Output Rate
The CheckPoint makes a TOC measurement every 15 seconds. The output rate can be changed to
select longer intervals between measurements, either by averaging the measurements that have
been taken in the last interval or by the last measurement for that interval. The output interval can be
set from 15 seconds to 8 hours.
Set the output rate as follows:
1. On the
Setup
screen, use the
Vertical Scroll
bar to highlight
Output Rate
, and then press
the
Enter
key.
