The process for a
PRIMARY
or
SYSTEM
calibration is the same.
1.
From the
CALIBRATION
menu, select
PRIMARY CAL
or
SYSTEM CAL
with the scrolling keys
and press
Enter
.
Option
Description
MANUAL SYS CAL
This calibration requires a laboratory prepared calibration solution(s) with known
concentration.
PROCESS SYS CAL
This calibration uses the process solution, with known concentration, as the
calibration solution.
AUTO SYS CAL
This is only available if this option has been installed.
Manual calibration
1.
Select
MANUAL SYS CAL
and press
Enter
.
2. FILL CAL SOL.
is displayed. Pour the calibration solution into the measurement chamber and
press
Enter
.
3. CONC SOL: XXXXX
is displayed. Enter the concentration as a five digit number with no decimal
point, or a four digit number with decimal point. Press
Enter
to confirm.
4.
If the
2 INDEP PTS
or the
TWO REAGENTS
option has been selected, the second point
concentration is required. Enter the concentration of the second solution and press
Enter
.
Process calibration
1.
Select
PROCESS SYS CAL
and press
Enter
.
2. CONC SOL: XXXXX
is displayed. Enter the concentration as a five digit number with no decimal
point, or a four digit number with decimal point. Press
Enter
to confirm.
3.
If the
2 INDEP PTS
or the
TWO REAGENTS
option has been selected, the second point
concentration is required. Enter the concentration of the second solution and press
Enter
.
Automatic calibration
This is only available if the analyzer has this option installed. It allows for an automatic calibration at
pre-programmed intervals, using a calibration solution of known concentration.
Note: If this is the first time this option is being selected, select NO to IMMEDIATE at step 3 in order to input
required additional parameters.
1.
Check the content of the calibration solution cannister. One calibration uses 250 to 300 mL of the
calibration solution so the capacity of a standard canister will allow 30 to 40 calibrations.
2.
Select
AUTO SYS CAL
and press
Enter
.
IMMEDIATE
is displayed. Select
YES
or
NO
followed
by
Enter
. If
YES
is selected an automatic calibration will start immediately. No more input is
required.
3.
If
NO
is selected, enter the
FREQUENCY
of calibrations. This is the number of titrations between
each automatic calibration.
4. CONC SOL: XXXXX
is displayed. Enter the concentration as a five digit number with no decimal
point, or a four digit number with decimal point. Press
Enter
to confirm.
5.
If the
2 INDEP PTS
or the
TWO REAGENTS
option has been selected, the second point
concentration is required. Enter the concentration of the second solution and press
Enter
.
6. INJ. TIME
is displayed. Enter the injection time of the calibration solution in seconds and confirm
with
Enter
.
ELECTRODE calibration
The electrode calibration requires two buffer solutions of known concentration to effect a 2-point
calibration. The buffer solutions should have different pH concentrations of between 1 and 9, or close
