calibRation / acceSSoRieS
StanDaRD Solution:
Myron L company standard
solution has a known conductivity and concentration
of sodium chloride (nacl). Your Dialysate meter was
calibrated at the factory using our 14.0 millimhos (7.86
grams per liter nacl) standard solution. You can keep
your meter accurate by using this same standard
solution.
checking calibRation:
1. test a sample of Myron L company 14.0 millimhos
standard solution.
caution:
throw the standard solution away as you
use it. Don’t put the used samples back in the bottle.
2. if the D-1 Meter does not indicate the 14.0 millimhos
shown on the Standard Solution bottle’s label, first
clean the cell. For directions on how to do this, see
ceLL cup opposite. rinse the cell thoroughly and
test the standard solution again. if the D-1 Meter still
does not indicate the correct value, recalibrate it as
described below.
to RecalibRate the MeteR
1. Remove the bottom cover using fingernails or a small
screwdriver to loosen the front or rear edge. identify
the calibration control (see photo below) so you can
find it by touch while calibrating.
2. test another sample of the standard solution (be
careful to not splash solution inside the meter).
3. adjust the calibration control until the meter pointer
indicates 14.0.
iMpoRtant
the plunger enclosed with your Dialysate meter has
been calibrated specifically for this instrument. If a
different plunger is used, the Dialysate Meter Must
be recaLibrateD with standard solution. Make
sure the plunger is completely seated in the cell cup.

StanDaRD Solution
Your D-1 Meter has been factory
calibrated with Myron L type 14.0
millimhos standard solution. Myron L
company Dialysis standard solution is
made with deionized water and reagent
grade sodium chloride, and is within
1.0% of sodium chloride reference
solutions. solutions are sold in quart
and gallon sizes. 12.5 and 13.4
millimhos values are also available.

note:
before measuring dialysate samples, check the
calibration of your meter using Myron L company 14.0
millimhos standard solution (see caLibration).
1. 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.

2. 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 per-
formed for samples at working (body) temperature to
avoid artificially low readings.
3. repeat steps 1 and 2 at least three times.
4. take another sample, drop in the plunger and press
the black button. When the pointer stops, iMMe-
DiateLY read and release the button.
5. repeat step 4 twice and record the last reading.
note:
if using the “safe zone” color band and the
reading is not within the band, immediately confirm the
calibration of your D-1 with 14.0 millimhos standard
solution (see caLibration).
6. When you are finished with the meter,
rinse tHe
ceLL cup with clean water, preferably r.o., dis-
tilled, or deionized.
caution:
Do not
use with samples hotter than 110ºF (43ºc).
the readings WiLL not be accurate.
Do not
splash solvents such as lacquer thinner, ace-
tone, 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 Mainte-
nance for instructions on drying it.
