Set The Measurement Logging Interval (1-Channel Analyzers) - Hach NA5600 sc Na+ Operations

c. For each channel, record the pH of the sample while the measurement status bar shows on
the display.
d. If the pH of a sample(s) is not between 11.2 and 11.4, set the Tgas/Twater setting for the
channel to a higher (or lower) percentage as necessary. Then, after 1 hour of operation, do
step c again.
e. If the pH of a sample(s) is not between 11.2 and 11.4 when the Tgas/Twater is set to the
maximum value, refer to "PH TOO LOW" in the troubleshooting table of the maintenance
manual to identify the problem.
7. When the conditioned sample pH of each channel is between 11.2 and 11.4, install the sodium
electrode back in the middle chamber of the measurement cell.

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 11.
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.
