4.7 Set the measurement logging interval (1-channel analyzers)
Set the measurement logging interval. Measurements are saved to the data log at the measurement
logging interval. In addition, the relays and analog outputs are updated at the measurement logging
interval.
Note: This procedure applies to analyzers that can only be plumbed to one sample source. For analyzers that can
be plumbed to more than one sample source, go to
analyzers)
on page 10.
1. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > MEASUREMENT >
SET MEASURE CYCLE > CYCLE TIME.
2. Enter the measurement logging interval (default: 10 minutes).
Note: The analyzer measures the sample continuously during the CYCLE TIME selected. The measurement
shows on the display. At the end of the CYCLE TIME, the analyzer saves the average measurement for the last
minute to the data log. In addition, the analyzer updates the relays and analog outputs so they represent the
saved measurement.
4.8 Set the measurement logging interval (2- or 4-channel analyzers)
Set the measurement logging interval. Measurements are saved to the data log at the measurement
logging interval. In addition, the relays and analog outputs are updated at the measurement logging
interval.
1. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > MEASUREMENT >
SET MEASURE CYCLE.
2. Select and configure each option. Select SEARCH STABILITY first.

Description
SEARCH
Between channel measurements, the analyzer rinses the measurement cell with sample
STABILITY
from the next channel to be measured for a set time interval (or until the measurement is
stable).
NO (default)—Sets search stability to off. The analyzer rinses the measurement cell for a set
time interval. As a result, the measurement logging interval is constant.
When SEARCH STABILITY is set to NO, the settings to configure are CYCLE TIME and ON
LINE MEASURE time.
YES—Sets search stability to on. The analyzer rinses the measurement cell only until the
measurement is stable, which minimizes the rinsing time. As a result, the measurement
logging interval is variable.
When SEARCH STABILITY is set to YES, the settings to configure are MAX CYCLE TIME
(maximum measurement logging interval) and ON LINE MEASURE time.
