FOR WATER QUALITY ANALYSIS SET: PURIFICATION (WQAS-P)
DESCRIPTION AND USE OF CONTROLS AND INDICATORS FOR ULTRAMETER 6P
There is a separate calibration for each of the 4 solution types. Note that calibration of a 442 solution does not effect the
calibration of a NaCl solution. For example: Calibration (ref. Conductivity or TDS Calibration) is performed separately
for each type of solution one wishes to measure.
D.
Procedure to Select a Solution
NOTE: Check display to see if solution displayed (KCL, NaCl, 442 or USER) is already the type desired. If not:
1.
Press <COND>, <RES>, or <TDS> which determines which
parameter is having its solution type changed.
KCL
SEL
NaCl
2.
Press and hold <CAL/MCLR> key about 3 seconds to make
442
"SEL" appear (see figure to the right). For demonstration purposes, all 4 solution types are
User
shown simultaneously.
Use < /MS> or < /MR> key to obtain type of solution desired. (ref. Solution
3.
Characteristics). The selected solution type will be displayed: KCL, NaCl, 442 or User.
4.
Press <CAL/MCLR> to accept new solution type.
E.
Application of USER Solution Type
1.
User Programmable Tempco
This feature allows you to change your Ultrameter's temperature compensating factor to another factor between 0-
9.99%/C (ref. Temperature Compensation). This feature does not apply to pH or ORP.
a.
As in Procedure to Select a Solution, select "USER" mode.
b.
With "USER" mode now selected, press <CAL/MCLR>. You may now adjust a
temperature compensation from 00%/C to 9.99%/C, by pressing < /MS> or < /MR>. See example in figure to the
right.
c.
Press <CAL/MCLR> twice to skip calibration
.13%/C
adjustment and accept the new tempco (3 times if in TDS mode). You are now ready to
User
measure samples with your new temperature compensation factor.
COND
2.
Disabling Temperature Compensation
a.
As in Procedure to Select a Solution, select "USER" mode.
b.
With "USER" selected, press <CAL/MCLR>.
If the display does not show 0.00%/C, hold < /MR> down long enough to bring the
.00%/C
tempco to 0.00%/C (See figure to the right.)
User
c.
Press <CAL/MCLR> twice (3 times if in TDS
COND
mode). Temperature compensation is now disabled
(=0) for measurements in USER mode.
3.
User Programmable Conductivity to TDS Ratio
This feature allows you to select a custom conductivity to TDS conversion ratio for USER mode requirements. For
example: The conversion ratio range is 0.20-7.99 (i.e., if conductivity is 100 S and TDS is 75 ppm, you would adjust to
0.75). (ref. Conductivity Conversion to TDS).
