Calibration
N O T I C E
The manufacturer recommends calibration of the analyzer after 1 day of operation to allow all system components
to stabilize.
The automatic calibration uses the installed known standards to calibrate the analyzer. Calibration
can be done manually or scheduled to occur automatically. Use the calibration menu to view
calibration data, start or cancel the auto calibration, override the auto cal settings, calibrate manually
or to reset to the default calibration.
1. Push cal to display the calibration menu.
Option Description
START MANUAL CAL Refer to Start a calibration manually on page 19.
SET AUTO CALIBRATION Refer to Schedule automatic calibrations on page 19.
CALIBRATION DATA Displays data from the last calibration and the due date and time of the next
scheduled calibration.
OVERRIDE CALIBRATION To calibrate the slope value, refer to the concentration value from the user
input. When override calibration is selected, the automatic calibration is
disabled.
OUTPUT CALIBRATION Select a 4-20 mA output and enter the output values to be sent.
RESET DEFAULT CAL Reset calibration data to default values and disables automatic calibration. On
completion, perform a new calibration.
Schedule automatic calibrations
1. Push cal, then select SET AUTO CALIBRATION.
2. ENABLE AUTO CAL>YES.
3. Select STD SOLUTION and enter the standard value in ppm.
4. Select a schedule option for calibration.
Option Description
TIME BASE Sets the interval between calibrations. Options: DAYS or HOURS.
WEEK DAY Selects the day or days of the week for calibration when TIME BASE is set to DAY.
TIME Sets the time of day for calibration when the TIME BASE is set to DAY.
SET INTERVAL Sets the interval between automatic calibrations in hours when the TIME BASE is set to
