Specifications subject to change without notice
Myron L Ds Meters have a limited two year warranty. if your
instrument fails to operate properly, check the batteries and
calibration. if it still fails to function properly, return it prepaid to
the Myron L company.
Faulty instruments may be returned to us without prior
permission.
meters within two year warranty period:
Failures due to materials or workmanship will be repaired or
replaced (our option) without charge if returned freight prepaid.
if failure is deemed by the factory to have been caused by
abuse or tampering, the following procedure will apply.
instruments/controls out of warranty:
Diagnosis will be made and repairs completed, providing the
repair charges are $70.00 or less.
note: actual repair charges may be less than this amount.
we will diagnose (but not repair) a returned meter and mail
an estimate of charges if anY of the following apply:
1. repair charges will be more than $70.00.
2. You specifically request an estimate of required repairs and
charges.
3. the cost of required repairs exceeds one-half the list price of
a new instrument.
4. the instrument is over ten years old. Because of component
changes and improvements, such instruments may no longer
be repaired.
note: unrepaired meters are discarded unless you want them
returned to you. if so, there is currently a $35.00 charge per
unrepaired instrument to cover diagnosis and handling.
this warranty is limited to the repair or replacement of the
Myron L Ds Meter only. the Myron L company assumes no

range extender
the re-10 range extender is a useful accessory for
testing high conductivity/ppm solutions beyond the normal
range of your Ds meter (except 512t10). inserting the re-
10 into a sample-filled cell cup increases the maximum
range ten times. use the range extender whenever the
reading is off the scale.
using the re-10
1. Fill the cell cup three times to rinse it, but each time
insert the range extender to rinse it also.
2. Fill the cell cup with your sample. push the range
extender into the cell cup, seating the o-ring seal.
3. use and read the Ds Meter in the normal manner.
Multiply the reading by 10.
4. For best accuracy, repeat the complete test with a fresh
sample.
5. when you’re done testing, remove the range extender.
thoroughly rinse the cell cup and extender with clean
water (preferably distilled or deionized) to eliminate
dried salts build-up. this is extremely important when
the instrument will be used to test high purity water.
calibrating the re-10
1. calibrate the meter (without re-10) using the standard
solution.
2. Fill the cell cup with appropriate high conductivity
standard solution (442-15,000 or 442-30,000).
3. insert re-10 and press the black button. Multiply the
reading by 10 and compare it with the value on the
standard solution label. it they are not the same the
re-10 must be recalibrated.
note: do not adjust the conductivity calibration
control.
4. adjust the white insert of the extender as follows:
if the reading is too high – push or tap inward.
if the reading is too low – twist or pull outward with
pliers.
note: the range extender is factory calibrated to a
particular meter. it should be recalibrated if it is to be used
with another meter.
