Myron L D-2 - Manual (Page 3)

USING YOUR METER
NOTE: Before measuring dialysate samples, check the calibration
of your meter using Myron L Company 14.0 millimhos
Standard Solution (see CALIBRATION).
1. Select the appropriate range for the dialysate to be measured
(0-10 for prefinalized bicarbonate,0-20 for acetate/bicarbonate
final dialysate).
2. Fill the cell cup to just above the top electrode with a sample of
the dialysate you want to test. The dipper end of the cell plunger
will deliver just the right amount. Be sure hands are clean and
dry to avoid contamination of the sample.
NEVER FILL THE CELL BY DIPPING THE METER INTO
SOLUTIONS!
3. Drop the plunger into the cell cup. Lift it about half way out of the
cell and drop it back in three or four times. Discard the sample.
NOTE: This procedure must be conscientiously performed for
samples at working (body) temperature to avoid artificially
high readings.
4. Repeat steps 2 and 3 at least three times.
5. Take another sample, drop in the plunger, and press the black
button. When the pointer stops, IMMEDIATELY read and release
the button.
6. Repeat step 5 twice and record the last reading.
7. When you are finished with the meter, RINSE THE CELL CUP
with clean water, preferably R.O., distilled, or deionized.
CAUTION:
DO NOT use with samples hotter than 104
°
F (40
°
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 SOLUTIONS. If liquid does
get inside the instrument, see MAINTENANCE for instructions on
drying it.
