range extender
The RE-10 Range Extender is a useful accessory for
testing high conductivity solutions beyond the normal
range of your EP meter. 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 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 your meter (without RE-10) using Standard
Solution number 442-3000 (EP) or KCL-7000 (EP10).
2. Fill the cell cup with 442-30,000 high conductivity
Standard Solution.
3. insert RE-10 and press the 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 Calibration Control in your
meter.
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: Each Range Extender is calibrated to a particular
meter. it should be recalibrated if it is to be used with
another Myron L meter.
