Setting a User TOC Offset
At extremely low TOC concentrations, very small changes in water system conditions
may make it difficult to use the TOC Autozero procedure for the purposes of achieving
instrument-to-instrument agreement consistent with the stated analyzer specifications.
If the TOC Autozero procedure does not yield acceptable agreement between multiple
instruments, use this manual
User TOC zero offset
adjustment to adjust the TOC
reading to match a known accurate reference value.
To set a user TOC offset
1. Navigate to the
Analyzer Settings
panel (
Settings
s
screen >
Instrument
Settings
tab).
2.
In the
User TOC Offset
area, click inside the
Offset
field and use the numeric
keypad to enter a ppb value between
-5.00
and
5.00
and click
OK
to save.
