10. SOFTWARE VERSION 3.0 COM-
PARED TO VERSIONS 1* AND 2*.
In 1994 the software of EXA SC200 has un-
dergone a major update as result of user
feedback. New features are made accessi-
ble by additional Service Codes to avoid
programming conflicts with users of pre-
vious versions.
10-2.Matrix compensation
ACCESS CODE : 13
Display : *MATR
Adjustment:
0 Only linear compensation (see access
code 10)
1 HCI pure water (0 - 100 °C)/CATION
2 Ammonia
3 Morpholine in pure water
4 Hydrochloric Acid (1-5%)
5 Nitric Acid (1-5%)
9 User adjustable matrix (see access code 15
NOTE:
Access to this routine is only possible when
manually set temperature compensation
factor (α) is selected in §4-4.
Explanation:
The SC200 is equiped with a matrix type
algorithm for accurate temperature compen-
sation in various applications. Select the
range as close as possible to the actual
temperature/concentration range. The
SC200 will compensate by interpolation and
extrapolation. Consequently, there is no
need for a 100 % coverage.
If 9 is selected the temperature compensa-
tion range for the user adjustable matrix can
be set in access code 15. In access codes
16 and 19 the specific conductivity values at
5 different temperatures is entered.
The new features are:
10-1. Cell constant
ACCESS-CODE : 05
DISPLAY : 1.00xC
Adjustments:
1. Select multiplying factor
2. Adjust the required cell constant
1. Select multiplying factor with keys
YES and NO.
2. With keys > and ^ any cell con-
stant between 0.01 and 50.0 cm
-1
can be selected.
Explanation:
1. Multiplying factor
- The multiplying factor is confirmed after
pressing the YES key.
- Change multiplying factor to 1.0-10-
10-0.01-0.1-1.0 by pressing NO key
and confirm selection with YES key.
2. The value of the cell constant is indicated
in the specifications of the cell and/or on its
identification plate.
Adjust the required value of the cell after
pressing the YES key to confirm the multi-
plying factor.
Select the digit to adjust with key > (digit
flashes).
With ^ key the value of the selected digit
can be changed.
Example: Cell constant = 0.00985
a. Select multiplying factor 0.01
b. Adjust the value to .985
