The CALIBRATION option is available for viewing the calibration parameters. Scroll
through the list of parameters as they are displayed.
1. From the PROGRAMMING menu, select CALIBRATION with the scrolling keys and
press Enter.
Option Description
MANUAL CAL This calibration requires two laboratory prepared calibration solutions with
known concentration.
PROCESS CAL This calibration uses the process solution, with known concentration, as
the calibration solution.
AUTOMAT. CAL This is only available if this option has been installed.
1. Select MANUAL CAL and press Enter. The measurement chamber is then cleaned
in preparation for a calibration.
2. FILL BUFFER 1 is displayed. Pour the first calibration solution into the measurement
chamber and press Enter.
3. CONC 1 XX.XXEXX is displayed. Enter the calibration solution concentration and
press Enter. The solution is then measured before the measurement chamber is
cleaned in preparation for the second calibration solution.
Description
From the list available, select YES for those additional options that have
been installed and NO for those not installed. For correct operation of
the analyzer, any hardware installations must have been completed
before setting the option to YES.
1. AUTOMAT.CAL - Automatic calibration. Define if the automatic
calibration is a 1 point or 2 point calibration. If set to 1 point, no
further input is required. For 2 points, set PULSE PUMP to YES if a
pulse pump has been installed or NO if a micro piston pump has
been installed and define the flow rate for the type of pump
selected. Next define the volume of the measurement cell and if
the calibration solution (STD ADDITION) is of known concentration
(YES or NO).
2. CLEANING - Chemical cleaning
3. SAMPLE COND. - Sample conditioning
4. MANUAL - External sample. Set the injection time (in seconds) of
the external sample
5. HEATING - Sample heating before measurement. Set the sample
temperature required
6. DILUTION - Sample dilution before measurement
7. 2 CHANNELS - Additional sample channel. If this option is
installed, measurements are taken alternatively on each channel
but calibrations are always made on channel 1
