NOTE
2. After the zero is complete, view the HOME screen and observe the
analyte output concentration changes. Observe and record the time it
takes the analyzer to display the first reading after the analyzer Sys-
tem State switches from “ Zero ” to “ Measure ”.
It is important to record the response time only after performing a
manual Zero function to simulate the same conditions during the
original recordings.
3. If the sample response time is adequate (first reading after a Zero
function and after the analyzer System State switches from “ Zero ”
to “ Measure ” is less than 30 seconds to T90), no further adjustment is
necessary.
The sample response time may vary, depending on Sample Line
length.
4. Record these signals in a log book every month.
