Set The Signal Average - Hach NA5600 sc Na+ Mode D'emploi

4.9 Set the reactivation schedule
With time, the sensitivity of the sodium electrode decreases because of the very low levels of sodium
in the sample water. Auto reactivation adds a small quantity of reactivation solution to the
measurement cell at regular intervals (e.g., 24 hours) to increase the sensitivity of the sodium
electrode. Auto reactivation increases the accuracy of the analyzer measurements.

4.10 Set the measurement units
Set the measurement units that show on the measurement screen.
1. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > MEAS UNITS.
2. Select the measurement units (ppm, ppb, mg/L or µg/L).

4.11 Set the signal average

Set the number of saved measurements the analyzer uses to calculate an average measurement
(1–5). At the end of the measurement cycle, the analyzer saves the average measurement to the
data log. In addition, the analyzer updates the relays and analog outputs so they represent the saved
measurement. The signal average setting decreases variability in measurements.
1. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > SIGNAL AVERAGE.
2. Push the UP or DOWN arrow key to set the value. The default is 1 (no signal average used).

Description
YES (default)—Sets auto reactivation to on. NO—Sets auto reactivation
to off.
Note: If reactivation is off, a reactivation is only done before a calibration.
DAYS—Sets auto reactivation to occur on selected days at a selected
time (e.g., daily at 9:00 am). HOURS (default)—Sets a time interval
between reactivations (e.g., 24 hours).
Note: The WEEK DAY option only shows when TIME BASE is set to DAYS.
Sets the days of the week that a reactivation is done. All of the days of
the week are selected by default. The default setting is recommended.
Note: The TIME option only shows when TIME BASE is set to DAYS.
Sets the time a reactivation is done in 24-hour format (default: 12:00).
Note: The SET INTERVAL option only shows when TIME BASE is set to HOURS.
Sets the time interval between reactivations (2 to 168 hours). The
recommended time interval is 24 hours (default).
