Myron L DS-1 - Manual (Page 3)

USING YOUR METER
1. Rinse the cell cup three times with the sample you want to test.
(For very hot or very cold samples see TEMPERATURE
COMPENSATION below.)
NEVER FILL THE CELL BY DIPPING THE METER INTO WATER!
2. Fill the cell with another sample to at least
1 /
4
" (6mm) above the
upper electrode.
3. Press the black button.
4. Read the dial value indicated by the pointer to determine parts
per million (ppm) Total Dissolved Solids.
5. If the pointer goes off the scale to the right, try diluting your sample
so it can be measured:
A) Pour distilled or deionized water into a separate container until
it is exactly half full.
B) Complete the filling of the container with your sample.
C) Test the diluted sample in the normal way described above.
D) Multiply by 2 the ppm value indicated on the dial. For Example:
A sample reading 900 after dilution would actually have a TDS
value of 1800 ppm.
NOTE:
When you are finished with the meter, RINSE THE CELL CUP
with clean water, preferably distilled or deionized.
TEMPERATURE COMPENSATION
For very hot or very cold solutions let the three rinse samples
each remain in the cell for several seconds, then immediately fill the
cell with the sample you want to test (step 2 at left). This allows the
automatic temperature compensation feature time to work properly.
CAUTION
DO NOT use with samples hotter than 160
°
F (71
°
C). The readings
WILL NOT be accurate
DO NOT splash solvents such as lacquer thinner, acetone, benzene
or chlorinated solvents on the plastic case.
DO NOT fix or modify the meter. That will void your warranty. See
SERVICE for details or consult Myron L Company.
DO NOT DIP THE INSTRUMENT INTO WATER. If water does get
inside the instrument, see MAINTENANCE for instructions on drying
it.
